The O.S. Speed B2101 is available in a special Gold Edition to commemorate O.S.’s 80th anniversary. A gold cylinder head and carb insert makes it extra-attractive for collectors, while the legendary O.S. performance makes it a must for high-octane racing.  It is a high performance engine produced by O.S.'s Speed Team technicians.

The B2101 was developed to fill a hole in the O.S. Engine line with an engine that produces a smooth power band, ideal for slick or blown-tracks. Its square 16.4mm bore/stroke dimension, combined with a DLC coated and balanced OS SPEED tuned crankshaft creates the perfect blend of power and driveability. Other features include a low slung, low CG cooling head that hangs below the engine case, for improved handling, and the renowned 21J carburetor for easy tuning adjustments.
