ENGINE SPROCKETS FOR BIG TWIN

Accurate cut and correct hardness are the most important factors concerning engine sprockets. These sprockets have the correct tooth hardness to be completely compatible with the primary chain and the greater hardness to be compatible with the engine sprocket shaft. These sprockets are cut to perfectly mate with the sliding cam (compensating style).
