No, this isn‘t your basic XR 750. Bruce Baxter wanted a race bike themed street machine so he had Richard Pollock of Mule Motorcycles build this beast which he dubbed, “The Punisher” (after a character in Marvel Comics). Famed tuner Dan Baisley started by mating Axtell cylinders onto a set of S&S cases. Then a pair of dual-carb heads with Keihin carbs (modified by Bob Woods) were bolted onto the engine. With 130-horsepower and 130-foot-pounds of torque coming out of the 100-cubic-inch engine the XR1660 street-tracker lives up to its namesake.

Meanwhile Pollock had to cut the C&J frame they used because the new motor was over an inch taller than stock. He lifted the frame’s backbone while keeping the steering head in its normal position. Racetec hand built the 3 gallon gas tank to fit the modified frame. A&A Racing triple-clamps hold the 45mm Honda CBR900RR forks with a Yamaha XS650 front hub laced to a sun rim. In the rear  Öhlins shocks are bolted to a modified C&J swingarm. The rear hub is a XR-750 style from A&A Racing laced to a Sun rim. The bike sports 19-inch Goodyear dirt-track tires. Naturally you want the bike to whoa up real quick so Brembo titanium-pistoned Monoblocs brakes were used.

My guess is that this bike will punish some unsuspecting riders at every stoplight. To see more of this bike go to: www.bikeexif.com/mule-motorcycles-2?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+Bikeexif+(Bike+EXIF)
