Hattar Motorsports in San Rafael, CA built a Triumph street tracker from a Scrambler. Lots of hand formed bodywork, custom frame, custom pipes and the engine was worked over, … a lot. Starting at 450 pounds and 39 rear wheel horsepower they finished with 320 pounds and 100 rear wheel horsepower. Gorgeous bike but not cheap.
After all of the discussion on the Kawasaki W800 article about low horsepower and comparisons to the Triumph, it’s interesting to see that if horsepower is what you want, you can always get it, no matter what you start with.
Thanks for the tip Mike!

I would love more information on just what “the engine was worked over” statement specifically refers to. (List of machine work and parts #s would be just fine, thank you!!!) That is a huge gain in HP!!

That tank is awesome looking. The exhaust is pretty cool too. I really like the way the axle line is at the midpoint of a triangle if you connected the exhaust tips.
todd says
impressive. You shouldn’t have any feelings of inadequacy with this one.

Really nice tracker conversion. Lots of details to ogle on this one!
Russell B! says
That is a beautiful bike, IMHO.
Quick Google search finds Triumph listing Scrambler weight as 506 and HP as 58, doesn’t spec rear wheel or crank for HP. I would be very impressed to see a dyno chart showing 100RWHP from that motor.
My old ironhead XLCH enduro w/flattrack frame went 375 pounds, so I could maybe believe 320 for this bike. Even if it were 375 and 75 HP I would take it in a New York minute.
Klaus says
Gorgeous looking bike – seems like nothing is stock, including the engine. But to get real-world 100hp you’d need a compressor! I agree, 75 should do, with lots of torque.
Why is it a street tracker if it doesn’t have any lights, signals or plate?
todd, like your tongue-in-cheek humor!
frederick says
tank and seat by evan wilcox?
Malove says
Why when i first saw this i thought it was one more great piece from Mule ? 🙂
Mule says
Love to hear what was done to the motor and what kind of frame that is. Looks cool.
Jody says
I agree. At first glance I thought it was Mule’s work too. As for the motor, I know Bonneville Performance builds such motors. There is a lot of power to be had from these motors, it’s just not cheap.
And I REALLY like that aluminum seat/tail!
Skizick says
Klaus, Look just under the 7 on the number plate for twin headlights
Scotduke says
Nice, very nice. Not sure about those pipes but those could be changed. The tailpiece is really neat and the power’s just about right.
BellaCorse says
For those of you traveling in the SF/Bay area, Hattar is a great destination to visit. A dealership that “get’s it.”
Oldtimer says
Hey BellaCorse: Bet this is a boon for you!! Snow is about 2 ft. deep here, but no worries! Been in the garage all afternoon getting the Bonneville ready for spring! Look for an order from me tomorrow!! Normally I would while away the afternoon verbally abusing todd, but I think I’ll chase some extra hp for this riding season instead.
HigherRPM says
Sweet! 100 RWHP might be a bit of a high stress engine. I got 70 RWHP out of a Norton 750 with a cam, headwork, mikuni’s and trick pipe. But the engine really didn’t like that much HP (many blow head gaskets)
Mule says
FYI “HigherRPM”, this is not even close to an old British bike of any manufacture. It has a 4-valve, chain driven overhead cam with shim and bucket adjustment head, decent ports and combustion chamber, counterbalanced and the crank and tranny could be used in an RV. The lower end is extremely robust to put it lightly. I’ve heard claims of as high as 118 HP at the wheel. They spin right up too! If you got 80 out of a Norton as Ron Wood did, you’d have a grenade on your hands. I’m not sure what the limit of potential HP is on these motors, but people are pushing to find out.
rafe03 says
Could use some more images. Can’t find any on their website.
Seat looks a bit large. Maybe thats due to the angle of viewing.
Sure is a beautiful piece of machinery
The No-Toil Guy says
This is awesome! I agree that the pipes are not my style but overall amazing!
B50 Jim says
I just finished shoveling a 4-foot drift from in front of my garage door after the Chicago blizzard, feeling every one of my 58 years — while my B50 resides under its cover. This is like a breath of Spring, and if it can really do 100 hp (I doubt it, but 70 would be more than enough) I’d love to take it for a 3-month test ride. The “aluminium” bodywork is truly art. The bike reflects all the best of the Trumpets that ruled the dirt tracks during the ’60s, without the negative aspects such as spitting the crankshaft out of the cases.
Byrd says
Really, really nicely done. Keeping the front wheel down would be a very enjoyable problem on that.
adeeb says
There are a few more photos here guys. I can post engine mods later so you can see how we got the power. Here is a link to a Thruxton we did with similar style as well as a video of it on the dyno. Some teaser videos before we unveiled them as well. Enjoy!
