BMW E46

The E46 experienced enormous success in all markets was widely considered the performance benchmark of its class. The highest performance bike is the Firebolt XB12R and Lighting XB12S with an 1203cc engine that develops a claimed 103 horsepower (77 KW). The BMW E90 coupe will be released in 2006. The Blast is the only model to use a 492 cc, 34 hp single-cylinder engine. In late 2005, BMW introduced the BMW E90 sedan which will replace the BMW E46 sedan. Earlier models included the RR1000, RR1200, RS1200 West wind, RSS West wind, S2 & S2T Thunderbolt, S1 Lighting, M2 Cyclone, S3 & S3T Thunderbolt and the X1 Lighting.

The ZTL front wheel is very innovative, but some see it as more marketing fluff than actual substance. Two of the notable innovations are the use of the hollow frame as a fuel tank and the hollow rear swing-arm to hold the engine oil. Buell claims that what differentiates their motorcycles from their Harley-Davidson origins is the "Trilogy of Tech": mass centralization, low unsprung weight and frame rigidity.

It also incorporated, but did not invent, the inside-out front brake and "fuel in frame technology." (first for the industry). In 2003, Buell introduced a whole new engine--so efficient it passed emission tests well into 2006. In 1995 the engines were upgraded with Buell engineered parts and further upgraded in 1998. These engines were originally built from Harley-Davidson XR1000 Sportster engines, after the 1000s were depleted Erik Buell used a basic 1200 Harley-Davidson Sportster engine.

Most Buell motorcycles use four-stroke V-twin engines. Buells typically employ radical frame designs and unconventional suspension systems that, along with the relatively high output Sportster engine, culminate in a nimble and atypical, however much less powerful and somewhat more expensive alternative to the Japanese sport bikes. Buell started with a stock Harley-Davidson "Sportster" engine, then highly modified it and bolted it to a frame of his own design. Mr.
