VS Racing VSR04 nitro on-road engine


World Champion Products have introduced the new VS Racing VSR04 3.5cc nitro on-road engine. The new and exclusive super long stroke .21 on-road engine is based on the powerful O.S. Speed R2102 and of the world famous O.S. Max technology together with some additional ‘Rody Roem’ touch and development such as the VS Bi-Turbo crankshaft and VS Spec combustion chamber. The DLC coating will increase the lifespan of the rotating parts, especially in the piston-area where the pin is exposed to high pressure from both piston and conrod. The crankshaft will resist better against wear in the conrod area but also at the intake area sometimes vulnerable to dust.
