Decisions often have far reaching effects. When Buell crushed the Blast, it caused a bit of collateral damage to the Mac Motorcycles plan of basing their new bikes on the Buell sourced 500cc single. After retiring to the pub for a “what now?” session, the boys at Mac came up with some alternative ideas and sent over this reworked image of the Spud with an engine from the Yamaha XT660.
A quick comparison of the specs shows a jump from 34 to 48 horsepower, a nice bump in a bike this size. The Yamaha single, in contrast to the Blast, is fuel injected and water cooled while offering parts and service from your nearest Yamaha dealer, not a bad thing. According to Mac, the pricing is expected to stay the same.
The Yamaha engine requires a frame change with an extra tube or two to mount the engine and radiator. It doesn’t have quite the clean look of the original air cooled single but remains far better than most (all?) of the other liquid cooled choices. Come to think of it, what would those choices be?
I assume there’s a weight penalty with the switch, they didn’t give any details, but it’s probably small and the extra power makes up for it in any case.
So, is this a good choice to replace the Blast engine? Does the look still work? Is this something you would want in your garage? Let’s hear your ideas.

Love the frame design and concept…pity they’re on the opposite side of the pond from me.
As for engine choices, I’d like to see something that’s easily tuned via aftermarket, and readily available for customers who’d prefer to roll their own to some degree (if sales of frame kits were even in the plans). Perhaps a somewhat generic frame with several different mounts for assorted singles/parallel twins? I’d like one with a RD/RZ/Banshee lump or the ability to fit one after registration 😉
"W" says
This is what the Blast should have evolved into under Buell.
Tom says
Big improvement. I’m doubtful there’s any significant weight increase, since the Blast! motor came with a 1952-technology Sportster transmission.
Joe says
What about a Suzuki Savage/LS650/S40? Granted the horsepower would drop even lower than the blast motor, but it would have great low end grunt, and you’d retain the cleanliness of the air cooling.
PaulN says
I think it looks better with the Yamaha power plant. I still can’t believe motorcycles are produced with carbs. The only things that warrant mechanical air/fuel mixing any more are lawn mowers and chain saws.
Wave says
I would’ve thought that, given the tiny production volumes and high emphasis on styling, the Mac Motorcycles company could have just bought 500 or so Blast engines before they went out of production, which would last them a good long while and avoid the costs of the redesign, both financial and aesthetic. That’s what I would’ve done, anyway.
W3Rm says
The right side really looks better with the Yamaha. Not because of the engine, but because the chain drivetrain, which moved to the other side of the bike. I enjoy much more the right side, now. I would like to see the left side, though. And if only someone could do something about the horrible brake/clutch oil reservoirs all over the handlebar…
angry j says
Still looks cool,but when can I get one?I emailed Mac Motorcycles 6 months ago along with a friend of mine & we both received the same lame form letter.By the time they get this company off the ground Yamaha will be sure to discontinue this power plant
Sam Beavin says
Think I’d put the radiator in that gaping hole behind the engine and put small scoops on the side to drag air in. Or 2 small radiators facing to the sides with a fan in between?
Phoebe says
I’d be very surprised if the bike takes on more weight with the 660; the Blast engine is heavy for its size. It’s more or less the Sportster’s engine sans the back cylinder.
Kenny says
I agree with most of the comments that the 660 engine is a plus. Though if you wanted the aircooled look the XR650 lump is an option though personnally my choices would be the Service Honda CR500 or the Aprillia 550 twin.
ADT says
I believe the estimated price was $12-17k which is insanely high considering it’s a great minimalist bike and you can buy a lot more for that price. It’s a great design, but at that price it will go nowhere.
Dorzok says
this is funny. just this past Friday I sent them a question through their web site what their plans are without the Buell. now i don’t have to wait for there reply. this is where they should have started to begin with. now maybe they can drop the price a couple grand. gotta be cheaper than that half a Harley motor.
nortley says
Sam, you beat me to it. Put the radiator where the oil tank would be on a classic, have the fan blow rear to front (for cooler air than that from near the engine) and exhaust via ductwork so’s to not recycle the heat. While this would cover the spine tube (a la H-D horseshoe oil tank), that’s no great aesthetic loss. While I realize that those massive curved backbones are good structures, they just don’t please this pair of eyes.
Reffect says
I have to say the Buell Motor is prettier. Given that, I’d welcome the extra power of the Yami lump–but I wouldn’t be shelling out that kind of cash for THIS bike for its power.
Lewellyn says
Puttin in the KTM690 Single with 70 HP would blast the streets. 😉
Paulinator says
I feel sympathetic toward you folks at MAC. You’ve kinda had your legs kicked out from under you. The 660 still looks great, but the HD powered unit nailed it. What about building from reconditioned Sportster units that had rear-cylinder-ectomies? The rear crank-case cover could double-time as an oil cooler mount.
Hugo says
The “massive” air-cooled engine certainly fits the image better then a “smaller” water-cooled engine. Also an air-cooled engine just fits the image of a “2 wheels, fueltank and an engine”.
To keep the image of a single maybe knock MAC should knock on the door of its “neighbour” Norton Motorcycles and ask for a 961 engine 😉
Oakland Johnny says
Too bad about the loss of the air cooled engine. I never was much of a fan of the Blast power plant, though.
Trading up for reliability, horse power & parts availability seems like a pretty fair deal.
Sure, the look isn’t as clean but…
Wouldn’t it be nice if the Mac guys could have found a cache of old SR500 motors in a warehouse somewhere.
That aside, I still want one. Maybe more than ever, now.
Bob C. says
Even with the added clutter of the Yamaha the bike still looks bare, in a good way mind you, compared to most other modern bikes. They should have made this change for added power alone whether or not the Blast was going to be around or not.
Yen says
The original styling with the Buell engine was so raw and simplistic, it had that appeal to it, but with a liquid cooled engine, the minimalistic look is kind of defeated by the more modern engine, although the extra power would be welcome, the original appeal of the bike is lost somewhat. this bike was designed for air cooled, stick with your original plans of an air cooled engine, and you should retain those customers MAC. A bit more power would be nice though…
JR says
It changes the look, but not necessarily in a bad way, more post-apocalyptic and less classy british, but still cool.
The XR650 engine has already been mentioned, that would look good. Also, if you really want to make a fast bike, a big honkin KTM single!
Bob says
How about 1 cylinder of an S&S motor? I also like the horizontal cylinder (Husky?) motor for the Aermacchi/HD, Ducati Supermono look.
Steve Lake says
Well, thats ok, but instantly loses it’s retro style and looks, it is a good engine, but no better than the aircooled SRX6, which looks really cool……whatever you put in it has to be aircooled….and thank god the buell engine is a gonner, you’ve only got to look on any forum discussion in the states regarding that engine, to see there were a lot of issues on reliability etc.
todd says
I don’t quite understand how Buell curtailing the production of the Blast would affect MAC. I don’t think they were planning on an OEM agreement with Buell. From what I understand of this sort of venture you’re looking to sell kits to 50 people per year that already have a Blast. More than likely those people aren’t starting out with a showroom floor example. There are still thousands of used Blasts around (not that it would be my preferred lump) to maintain this business model. It would be illegal to sell them as “NEW” anyway unless you have the aforementioned OEM agreement and certification from DOT and CARB/EPA.
-todd
Steve Lake says
or how about the ABASF goldie rep engine and a quaif 5 speed box….that’d look really cool
zonk says
Typical Buell short-sightedness. Get rid of the Blast and not consider the flow-on effects like training schemes and small bespoke manufacturers like Mac. Bit like Buell styling and design – not well thought out and a bit “off-target”.
Yammy motor doesn’t look too bad though.
marvin says
That will be a lot more practical and increases the appeal of the bike to me without drastically reducing the cool looks. Something about the big tube reminds me of the sachs maddass which I don’t regard as a bad thing. I think I agree with the radiator placement as it needs no fans or scoops and leaves the big spine frame which sort of defines the bike uncluttered.
Tin Man 2 says
Correct me if Im wrong (It happened once before) But Im pretty sure the Blast will stay in production to supply HD with bikes for the Learner Program. The Blast will not be marketed to the public, but will continue to be available for dealer purchase. I would think HD would still sell these crate engines to a serious manufacturer. How many of these bikes will ever be made? At such a premium price Im sure the numbers will be low. As much as we like this bike how many will pay out over 10K for it?
frozen prairie says
Suzuki still sells the DR650 here in Canada. it’s air cooled and has decent power. How about that mill?
@pauln, I still like carbs. I don’t know why people think they are trouble. They are beautiful passive systems that don’t require electricity to work and don’t need an expensive, failure-prone, in-tank fuel pump.
Same goes for liquid cooling. Sure, on a race machine the thermostat helps keep the temp fairly constant, but on a non-race tuned motor air works just fine. Liquid cooled bikes need to have the coolant changed periodically, water pumps break down eventually, gaskets fail, etc.
I own a liquid cooled motocross bike because that’s all they’ve built for the last 25 years or so, but I miss the ease of service of my old air cooled racers (and the racing was just as close back then). Pulling the cylinder to have a look at the piston and ring on my air-cooled bikes only took a couple of minutes and could be done in the pits between motos. My liquid cooler is waaay overdue for a new ring because it’s so much more hassle to change…. Sounds like my design philosophy is linked to my laziness, doesn’t it ?
In general, what I want from bike makers is LESS, but most of them are trying to give us more, more, more.
Nicolas says
Good move ! more than decent hp output, reliability out of any suspicion, tons of available parts, probably still room for improvement with aftermarket parts, and it doesn’t hurt the design. Way to go !
FREEMAN says
I like the simplicity of the Buell Blast motor and the look it gave this Mac custom. As a Buell Blast owner, the thing I hate about it are the position of the rearsets and the gigantic, heavy muffler, both of which make servicing it a bit of a pain due to clearance issues. With those two things gone, whether with this chassis or your own aftermarket/custom rearsets and exhaust on the original, the bike is a pleasure to service. Since, I take it, Mac is abandoning ship like Captain Buell himself, I guess we’ll never see this motor in anything like this.
Slide says
I’m on waiting list for one of these.
This just makes me want it more.More power,more reliable, more tuneable, same good looks.
Happy as a pig in the proverbial!
Jon says
I think if they had started out with a modernish single (like the Yamaha), I would have been all for it — however, the Buell engine does look far and away better.
Perhaps there is another air-cooled engine that would do the trick and still look nice.
As for the horsepower increase…so what? If your thing is ‘more power’, then this is not the bike for you. Image, comfort, sound, and feel should all be held to a higher level of importance than horsepower.
nobody says
Or just dump the weak yet still heavy single cylinder engine fetish and do it right with a 1200 Buell twin. Double the power for only a few pounds of aditional weight. It should be easy to do vaporware engine swaps!
If sporty custom singles are your thing…….
http://denver.craigslist.org/mcy/1360190014.html
Kenny says
Jon have you ever owned a small bore road bike?
10bhp increase is a significant amount on a small bike like this.
fazer6 says
Ruins the look, which used to justify about $5k of the bike’s asking price. With a water-cooled lump, it pulls in into competition with a lot of other bikes that do more for less dough.
WRXr says
I agree that the Buell engine looked much, much better. If they could do something to tidy up the hoses and whatnot on the Yam, it would the aesthetics.
Jimmy says
It was “good” with the Buell motor, but this is FANTASTIC!!!!!!!!! Now we have a real bike which MANY people will want. The 660 Yamaha is a real thumper. Proven and modern. Now this bike can be used for daily commuting as well as week-end touring. 660!! Holy Crap!
Jimmy says
However… It’s still not worth $10,000 USD. Mac CAN put a dent into the US market for people looking for a reliable, custom-standard bike in a big, big way.
Billy B. Tso says
i think with a tidy up (hide all the ugly bits) around the engine, it would still look great! agree with one other comment about cleaning up the handle bars as well…this bike goes to great lengths in looking clean and minimal, would be a shame for the minor bits and pieces to ruin the look! but overall, still thinks it’s a ripper bike design!!
Daniel says
One is a bike that looks really nice, the other is a bike that I would seriously consider buying. Guess which is which.
Randy says
Don’t like the frame style, looks like something unearthed at a metal yard.
The 660 engine is a step in the right direction but pretty mild….
Benjamin says
I agree with others in here – pressure S&S to build a single cylinder engine for you. Can’t be too hard can it? The XT motor looks OK but it loses the retro feel. The XR650 motor is not ‘classically pretty’.
Jacquie says
I loved the Buell single look. The Yam looks ok the liquid cooling loses a bit for me. The big DR might be ok or XR. Keep the carb. You get tinker with them to get right and other fun stuff.
Ry_Trapp0 says
Christ, PLEASE find a new air cooled engine to go with!!! As good as that Yamaha engine may be, it just plain looks terrible, and looks are possibly the biggest selling point of this bike! If I had the cash in hand, I would totally take a lower HP air cooled single over this. I’m not saying that it looks ‘bad’ now, but it just looks like it has potential to look great instead of just looking great in the first place.
Besides, like others have said, I’m not quite sure why the engine switch. H-D will still be producing the blast, and I really couldn’t imagine that it would be an issue buying some engines from them(though, I’m not the one behind the desk making these decisions either).
Though the looks have taken a nose dive, I would still totally consider buying one of these though. There is just nothing like it on the market.
Ry_Trapp0 says
…It appears that their website hasn’t been updated, as they are still displaying the Blast thumper as their engine of choice.
http://www.mac-motorcycles.com/motor.html
An interesting note, it almost sounds like they were going to modify the engine instead of running it stock, though I may be just misinterpreting that.
Rollin' Free says
I second Ry_Trapp0,,,please oh please find an air-cooled mill for those bikes…so much simpler and cleaner looking…and plain appropriate. Next, let’s talk about getting that price down a bit….
Scotduke says
The Buell motor looked good but the Yamaha engine increases performance and reliability significantly.
Thiago says
Honda makes loads of air cooled engines that could fit…even a Suzuki DR400 would fit the bill.
Wol says
It looks like the 1200 sporster motor would slot right in. Twice the cylinders and no pain.
SteveD says
I agree that althoguh the thumper idea is nice, it’s just too expensive to sell many bikes. That price would make more sense with a v-twin of some flavor. I have a Savage and a Sportster and I like the lighter thumper, but it also costs only $4500 for the newer S40. Not a good ecomony for niche bikes.
todd says
Or we could just figure out how to import (or re-manufacture) the Suzuki 650 Tempter:
http://www.suzukicycles.org/photos/suzuki-history/1997/1997_Tempter_490.jpg
The engine is still available in the Savage, I mean S40, and makes the sort of power that this type of market expects (30 – 40 HP).
-todd
SteveD says
The Savage/S 40 engine has been around a surprisingly long time. There used to be a carburetor upgrade kit to increase the hp a bit.
Motorod says
I like the brutish little Yammie motor in such a sweet package. It really looks all nasty business. I mean, the air-cooled Blast “looked the part” and all, but if I recall the old lungers of yesteryear were heavy and under-powered. Not what I want in a modern bike. Besides, nostalgia isn’t what it used to be, and you can’t beat modern motor technology.
As with any small bike there’s always a trade-off between the power-to-weight ratio and engine displacement. Twins are nice and powerful and all, but they’re damned heavy. I think a bigger motor in this little lovely would just spoil it. The Yammie single they’ve chosen is simple, ugly and just a little raw when you’re on the throttle, a sweet juxtaposition to the clean design. For a little beauty like this, keeping it light, quick & fun should be just right.
Too bad I’m in California. We’ll never see ’em here.
frozen prairie says
Ok, the more I look at the bike with the new engine, the more i like it. Yamaha claim 48HP for the 660, which should move it along nicely, and it’s been around since 2004ish (?) and I haven’t heard about any problems with it.
If Mac could just find a way to keep the price down without compromising the machine too much….
Bob says
Granted these Mac bikes have a certain style that’s appealing to some of the people posting, but, the running gear wouldn’t be all that different from the MuZ Skorpion that didn’t sell to well when they were available in the states. People say they like single cylinder street bikes (distinct from DP or motards), but, aside from entry level bikes 250cc and down it seems like they haven’t ever sold well: SR500, SRX-6, FT500, GB500, MuZ Skorpion, Savage, … It seems like the Buell Blast and the vanilla version of the F650 (Funduro) benefited from being the wife/girlfriend bike for the guy buying the Buell/H-D or BMW.
Boog says
I owned a Savage LS650. The thing had a GREAT engines, enough power for 75 mph cruising on the interstate. It looked like a Sportster, with one cylinder. But alas, like a Sportster, you were ready to get off after 40 miles…
This machine is interesting, but lose the “C” shaped frame backbone tube <<>>…since we are going for a “minimalist” look, why not a traditional hardtail frame. With such a frame, you could even use the engine as a stressed member instead of downtubes in the front, or not, depending on the engine chosen. For those with tender butts, I have seen decent looking “hardtail” styled frames that incorporated a suspension system. Also, the wheels (or more specifically, the tires) seem to me to be a bit massive for the concept, but perhaps I am just being a bit old-fashioned.
What would get my attention and get me into a showroom would be a big single in a “featherbed” type frame done up in cafe style…something on the order of the old BSA singles of old…
REAL motorcycles have either 1 cylinder or 4 in a row.
Buellman says
Love the looks of this single cylinder road bike with the Yamaha, prefering the more modern engine. Any chance you could talk Ducati into providing a single cylinder engine for you? While an S&S single may be an option, I suspect it would be out of scale (and quite expensive). a.k.a. http://thekneeslider.com/archives/2007/08/08/notorious-by-roger-goldammer/
Adrian Flores says
I like the switch. 1000% improvement in reliability and efficiency; which is what motorcycles are about.
Thiago says
A Husqvarna single would be even sweeter…the SM 610 has much more power than the XT660…
S_design says
If people from MAC are reading these comments, I would like to say that with this engine which is cluttered, and clearly shows that it was not built for this kind of (design) application, plus with a radiator sticking out like a sore thumb, and not to mention the extra parts of the frame. The bike has moved away from your design philosophy.
Your design philosophy which I get from reading your site and looking the bikes is “simplicity”. In a naked/minimalist bike engine is not only the heart and soul of the machine but it also represents the energy which drives the creative process.
Do not compromise on your vision! Japanese engine that deserves to be hidden behind few layers of plastic is not the way to go.
Craig says
I wrote Mac to let them know about this article – so if they didn’t know about it before, they do now.
Though, from their latest tweet (http://twitter.com/macmotors), they’re set on the Yammie.
Honestly, I’m getting used to the look of the Yammie – but the Blast engine still wins out. And when I contacted H-D/Buell the CSR who helped me put me on hold to go talk with a Buell tech on site – who said ‘there are no plans to discontinue the engine’. If that’s true, then Mac needs to do some more research; needs to fight for what they want.
Terry says
If the Mac is to sell in any decent numbers then air cooled options are extremely limited. There are very few still around that will clear noise and emission regs, especially in the States. Have any of those suggesting random air cooled lumps tried to buy these engines in numbers greater than one second hand? This isn’t a case of finding one on ebay- there needs to be a reliable supply with aftersales support. Even if the Blast is continuing as the outcast non-Buell I don’t imagine getting a supply of engines to England will be easy.
clone5 says
I’m gutted!!
If they wanted to go with a Japanese engine there are so many better looking models they could have chosen.
This has ruined my most anticipated motorcycle release ever!
kawi Zrider says
totally agree with those on the air cooled is cool look, there are still tons of japanese big singles out there! Or like someone else posted, go big with the 690 Ktm, that woulcd be more worth the big price
Randy says
It’s just the minimalist look – it’s appealing, even when it’s ugly. Wonder what a california legal version would look like?
I’ve ridden a bike with the Yami 660 engine, the MZ Baggie, it was SLOW. Like a F650, DR650, XR650L, SR500 is slow. I know slow, I even kind of like slow. I’ve owned three SR500’s, a SRX600, a F650, and now a DR650. I’m an expert – I can recognize slow when it’s happening. This bike will be slow unless they put something like the KTM690, XR650R, Husky 610 (all not happening) in it. I vote for a hopped up Rotax, that should only add about $4K to the price. Oh, then you could get a 1198 for the same price…
Howster says
I really liked the cleaner look with the Buell. I have owned Yamaha in the past and they make a nice product, but the original images with the Buell are what really turned my head and got my interest. I would be interested in purchasing one of these bikes if they did something with the price. Not much else I can say but it is beautiful.
todd says
I wonder if the new 2010 emissions regulations is why Buell is no longer offering the Blast motor. Buell can build it for training courses since those are considered “off-highway”, “closed course” venues. If the Blast motor doesn’t meet 2010 compliance then MAC won’t be able to offer new ones for the street. Best would be to offer it as a kit – sans motor. It would be up to the new owner to figure out how to get the old VIN off the donor Blast frame and onto the new one without anyone knowing…
-todd
Samuel says
Regardless of the power of the Yamaha Mill, the visual impact of the air-cooled motor is gone. From a design standpoint, the negative space that was occupied by the air cleaner and lower transmission is jumbled with the new layout. The engine is farther back in the frame and the front is cluttered with the radiator.
The proportions of the tank and frame now look stressed and unfinished. For a quick study to see if the engine would fit, I think this is sufficient, but MAC will have to completely redo the design of the bikes if they go this route.
Tin Man 2 says
Why the recuring concern about reliability with the Blast Engine? This is a typical understressed HD design that despite being air cooled will last forever. Since when has a Carb been unreliable? A 500cc single is a nice size for this type of bike, Horse Power that is high up in the Rev range is not used in street riding, Down low Torque or Grunt is what makes a single fun to ride. A person would be better off studying the Torque figures, not the HP numbers when considering a street bike. (old guy talk)
Randy says
Study the torque figures? OK. A low compression 500cc single like the Blast makes what – 30-33 ft/# and it signs off around 6,000rpm? That’s not a lot of power Old Guy (I’m an Old Guy too). Yes, most singles come on with decent torque right off of idle – the “grunt” thing. The problem is at what cost is this “grunt” had? First, for this bike, there is the dollar cost and this bike will be expensive, if it is ever produced. And then there is the low horsepower thing – having nice lowend grunt is offset by the torque ending early. So the bike is going to be a dog on the highway (I know this for a fact) unless it has a relatively powerful counterbalanced engine like the KTM. The Yami 660 is, ahem, on the mild side. Paying $10K+ for a slow bike is going to narrow the customer base way way down.
Isn’t the Blast engine uncounterbalanced? If so that has a number of disadvantages, like blurrrrrred vision and rattlttltlling teeth. I’d think it wouldn’t it’s a big deal to “stress” these engines to a higher level. My stage III (cams,10.3-1,ported) Sportster is making a solid 80+HP based on the mid 12 runs I’m doing on it. Surely there are Buell TS parts that just bolt on. That would be a lot cheaper than a Woods Rotax.
There are those that think 30HP, leisurely acceleration, and a 90mph topspeed are just fine. I’m sometimes in that group. However, this simply isn’t marketplace reality, it’s been proven many times. For all my slagging on these slow bikes I still kind of like them (I like Ducati’s too), but I think my next indulgence in the Slow World will be a Royal Enfield. At least it looks good (to me), not like a giant C-clamp with a motor.
Nick says
Why don’t mac just sell the bike as a kit, so customers can source there own buell engine. The blast is a very cheap bike, buy a mac kit and hey presto you have a cool sunday ride for a reasonable price, instead of the insane £10k.
Kind of like building a mondeo into a dax cobra!
ian says
The appeal of the Mac can be summed up in one word – LOOKS! While the Yammie mill may be better in terms of power, reliability etc, it falls well short of the Blast motor in aesthetic terms. My vote? Fit the 500cc single Royal Enfield motor from India. It’s pretty under-powered but will certainly look the part!
MadDog says
Excellent looking, but far too much money, Typical E.Pitt. should be made as a kit, then source a decent motor of choice.
Lee says
After a lot of reading, asking, researching and designing whist for over 2 months trying and trying by phone and e-mail to talk to Mac (Mr Pitt owner) this is a considered conclusion. Originally 5 designs: 2 to many, as they are to similar for no reason. Feedback was interesting, principally good in design but a little to simple and bare. DIY servicing aside, it does need a little more, especially in justifying the very high £8k + asking price! A third design option was also left out the equation which really is a surprise. YES you might say “Easy To Criticize”, but redesigning has been done, and by all accounts is going down well, (viewable on-line: all versions, single and the new engine…(except EIGER model).
(coroflot.com = PORTFOLIO’s and under search type in Lee Thompson).
The engine has been a problem in replacing, but the viewable concept design would work giving it a little more cosmetic appeal, usability whilst remaining alternative attracting both male and female riders, who never receive a designing thought. The original brief if correctly understood was to keep it simple, old, modern with a twist of retro with its own identity. Have a look, or e-mail as your views would also be well appreciated. Its grateful and thankful feedback that everyone contributed towards in achieving an 80%+ illustrated thumbs up. The new concept names are the SWOOP and GATSBY ( EIGER still under development…) Thanks for reading this comment…ride safe…
tailgunn says
I traded emails with that Pollock dude of Mule Motorcycles about the Blast motor. He built a one-off flat tracker from one and he said the motor weighs a ton. Probably a good thing they were forced to switch.
