OS Speed T1204 .12 engine

OS Engines have released their new OS Speed T1204 .12 engine. Featuring improved torque at medium to low speeds, the throttle response has also been improved. This has been achieved through a newly designed crankshaft with different counter weight shape which has had two tungsten weights installed for improve performance. The cooling head has also been changed to improve cooling, while the button and its o-ring has been modified to prevent dust entering this area. The T1204 is sold separately or as a combo with a TT01 EFRA2672 silencer with EX manifold MT03.

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.

Coming from Hasi Tuned is a new rear engine backplate for O.S. based .21 engines as well as a pressure chamber set.
