A new piston/liner 9 ports for more faster climbing in rpm and in addition a new cooling-head where it is more easy to reach the engine fixation screws.
The VSR05 is suited for high competition 1/8scale on-road racing.
This engine is intended for "EXPIERIENCED" users.

A special interest goes to the DLC coating technology which 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 itself will resist better against wear on the conrod area but also at the intake area where sometimes dust passes.
