O.S. Speed B2104 buggy engine

OS have introduced the new OS Speed B2104, a long-stroke .21 offroad engine, featuring quicker response in the low range and more torque in middle range, along with consistent idling. The new piston/liner is conventional 3-port type enabling more torque over the power range, while the new crankshaft has DLC coating and two tungsten counterweights embedded in the crankshaft contributing to consistent idling and quick return to idle. The boost port and the exhaust port of the crankcase are redesigned for optimum air flow, while the rest of the engine remains familiar with the use of 22E type carburettor and conventional round-shape cooling head with standard height. Also available as part of a combo with the TB03 (T-2100, EFRA 2155) silencer with 80mm manifold.

OS Speed Ronda Drake B21 engine

OS Engines in Japan have announced the release of the new OS Speed Ronda Drake edition engine. Identical in specification to the latest Adam Drake edition B21 engine, we would argue that his wife’s engine looks much cooler with its pink cooling head with black and white print and matching pink venturi insert. Originally only meant for the US market, the Japanese company has decided to make it available to all markets in an engine only or combo kit.
