Features:
By adopting a boost bypass processing for the crankcase, the engine runs more smoothly.
ADAM DRAKE's image color, blue anodized aluminum is applied to the cutting part of the new outer head, and two-color anodized aluminum with new design is used to reduce weight and lower the center of gravity and improve driving performance.
In addition, by adopting a cover plate with a built in 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.
Blue anodized restrictors, 6.5mm for buggy and 7.5mm for truggy comes standard.
