Great for buggy and truck racing.
Redesigned cylinder liner with optimized porting.
DLC crankshaft with larger double tungsten counterweight.
Semi-long stroke configuration.
Pink anodized 6.5mm(Buggy) and 7.5mm(Truggy) carburetor reducers included.
Ceramic rear bearing.

O.S.SPEED P3 gold plug, great for medium and low speed torque performance, is also included
By adopting a boost bypass processing for the crankcase, the rotation is increased smoothly, making it even easier to handle.
By adopting a thrust plate, wear due to interference between the connecting rod and the cover plate during rotation is reduced and engine life is improved.
The inner head uses an O-ring to reduce vibration and improve dust resistance.
