HOT CAMS Exhaust Camshaft - Stage 2 (Manufacturer Ref: HC00062)

Designed for motocross machines, this HOT CAMS Stage 2 camshaft is aimed at more advanced modifications. Developed on test benches and validated by competition teams, it alters the exhaust lobe profile to optimise valve opening for high RPMs. Use it as part of a suitable overall preparation (high compression piston, enlarged carburation, etc.).
