The MAX-21XR-B Version II was designed with the club racer in mind. Whilst you are honing your skills on the track as a club racer, the very latest all-out international competition engine is just a bit too extreme, so OS developed the MAX 21XR-B Version II to give strong power and crisp throttle response at a much more wallet friendly price!
The OS quality is of course a given, but the more linear power delivery comes courtesy of careful design and material selection plus testing. This new version of the MAX 21XR-B is a development of the original and benefits from the constant OS development program to move performance to a new level.
To obtain that peformance plus reliability, OS recommend to only use OS glowplugs, for which there are sevaral choices for the discerning modeller and high quality fuel.
The MAX 21XR-B ver II is the ideal engine to start off-road racing!
