After the review of Motorcycle Drag Racing: A History, my eyes kept stumbling over anything related to acceleration and while checking out the April issue of Cycle World, there it was, the S&S Dragon, a Harley Davidson Road Glide Ultra, not something you would normally associate with performance, but this one is different, it's equipped with the S&S T143 Long Block engine, the largest offering in their catalog that fits in the stock bagger frame. That's 143 cubic inches (2,343 cc), over 160 rear wheel horsepower and 170 pound feet of torque, ... in a Road Glide Ultra. No, this isn't really for cruising, this is for drag racing, but it does cruise just fine.
Of course, if the only thing you swapped out was the engine, the rest of the bike wouldn't be up to the task, the Dragon has Ohlins suspension, Lyndall discs, Brembo calipers, Pirelli tires, plus a long list of parts from S&S, DynoJet, Brock's Performance and lots more, a 3 inch primary drive, big clutch, a chain drive conversion, carbon fiber wheels, an air shifter and lots of time and effort putting it all together.
Price for the engine alone is north of $9,000 plus all of those extras before your bike is ready to go. The CW article says the Dragon is a $40,000 package, but you'll have the fastest bagger in town. Yes it's expensive and sport bikes are cheaper, but on the fun factor scale, this might make a pretty good trade off.
I like this from S&S on their T143 page:
At double the HP of a stock motor the power of the T143 requires technical expertise for the installation and tuning along with an experienced rider. This is an ultra performance/ race engine. Longevity, engine noise, vibration and throttle sensitivity have all been compromised to reach this level of performance while fitting in a stock chassis and as such is not suitable for every situation.
Ya think? OK, but it looks like the most fun you're ever going to have on a big Harley, so you can expect quite a few guys with deep pockets to be lining up.
OK, OK, I know you're not really interested, but the video below shows the eighth mile at 6.82 seconds and 106.58 mph. S&S says the quarter is in the nines, ... on a bagger. Wouldn't it be neat to roll up next to a Ninja or an R1? 🙂
