The Buell 1125R is a sport bike manufactured in the United States by Buell Motorcycle Company. It went on sale in July 2007 for the 2008 model year. Production of street-legal 1125Rs, as well as other Buell variants, halted in October 2009. Erik Buell Racing, founded by Buell creator Erik Buell in November 2009, initially created race-only versions of the 1125R.
The 1125R is powered by an Austrian BRP-Powertrain (Rotax) 1,125 cc (68.7 cu in) Helicon V-twin engine. The liquid-cooled engine has a 72° V angle and develops 146 horsepower (109 kW) at a maximum rpm of 10,500. Motorcycle Consumer News measured 127.1 horsepower (94.8 kW) and 71.1 lbft (96.4 Nm) at the rear wheel, whereas Cycle World measured 134.0 hp (99.9 kW) at 9,800 rpm and 75.9 lbft (102.9 Nm) at 8,300 rpm. Top speeds were stated to be 158 and 161 mph (254 and 259 km/h), with 0 to 14 mile (0.00 to 0.40 km) timings of 10.51 and 10.39 seconds at 134.32 and 134.09 mph (216.17 and 215.80 km/h).
The Helicon engine’s 72° configuration distinguishes it from Buell’s earlier V-twins, which were based on 45° air-cooled Harley-Davidson Sportster engines upgraded for increased efficiency and output.
The 1125R features a variety of unusual design elements. The gasoline tank is housed in the innovative frame design. The ZTL2 single-piston front brake features a 375 mm (14.8 in) inverted rotor that is directly linked to the front wheel rim. Buell was able to create a front end that was lighter and more responsive than traditional designs as a result of this. For increased volume, the bike also has an exhaust under the engine. Buell’s fundamental design goal of mass centralization is supported by the frame, front end, and exhaust. Instead of a drive chain, the 1125R employs a drive belt that requires no maintenance or adjustment.
