Have an AMA race license, the urge to compete in American Superbikes on an American superbike and $39,995 burning a hole in your pocket? Well then, Buell’s got the bike for you. The Buell 1125RR is designed to be a turnkey entry for privateer racers.
The 1125RR uses a modified version of the Rotax 1125cc v-twin found in
the regular Buell 1125R and Buell 1125CR, here with a larger airbox and
intake manifold, revised valves and camshafts, a higher compression
ratio, titanium exhaust system, 61mm down-draft injectors.
On the chassis side, the fuel-containing frame remains the same as the
production bike, but is fitted with race-spec Showa suspension, a
cast-aluminum swingarm with billet axle adjusters and an upgraded
eight-piston Nissin front caliper.
For those of you as confused as us by DMG’s racing classes, American Superbike is the class with CBR1000RRs, ZX-10s, RSV1000Rs, 1125Rs and slick tires, not the class with CBR600RRs, ZX-6s, RSV1000Rs, 1125Rs and DOT tires.
