Buell 1125R
Encyclopedia
The Buell 1125R is a sport bike
that was manufactured by Buell Motorcycle Company
in the United States. It was introduced in July 2007 for the 2008 model year. Production of road-going models ceased in October 2009, when Erik Buell
announced the cessation of production for the entire Buell range. In November 2009, Buell founder Erik Buell launched Erik Buell Racing
, which produce race-only versions of the 1125R.
It is powered by a 1125 cc Helicon V-twin engine produced by BRP-Powertrain (Rotax)
of Austria. This liquid-cooled engine has a V angle of 72° and produces a reported 146 hp, with a maximum rpm limit of 10,500.
The 72° included angle in this engine is a change from previous V-twins from this manufacturer which are 90° (Ducati, Suzuki
, Aprilia
) or 60° (Aprilia, Can-Am
), or 45° (Harley-Davidson Evolution engine). Voxan
was also using 72° V-twins.
The 1125R includes a number of unique design attributes. The patented frame design houses the bike's fuel. The single, eight-piston front brake, called ZTL2, features a 375 mm (14.8 in), inverted rotor that is directly attached to the bike's front rim. This feature allowed Buell to design a lighter, more responsive front end than traditional designs. The bike also utilizes an exhaust under the engine for greater volume. The frame, front end and exhaust all contribute to Buell's main design theme of mass centralization. The 1125R uses a drive belt instead of a chain, which does not require lubrication or adjustment.
