HOT CAMS Exhaust Camshaft - Stage 2 (manufacturer part number 4281-2E) for Yamaha YZ450F. Designed by HOT CAMS, this stage 2 camshaft is part of a range developed on test benches and proven by motocross teams. It is aimed at riders looking to push the engine preparation of their YZ450F further.

• Stage 1: improves response and torque curve without major modifications — a solution for light tuning.
• Stage 2: suitable for significant modifications; to fully exploit this camshaft, it requires other modifications (e.g., high-compression pistons and revised carburation).
• Stage 3: intended for specific uses such as supermoto or increasing displacement (reinstallation with original springs).

The kit includes two complete sets of shims to allow for precise timing adjustment. We strongly recommend installation by a qualified professional: timing adjustment, clearance checks, and appropriate tools are essential to ensure reliability and safety.

Compatible with Yamaha YZ 450 F (CJ18 models 2014-2015). This product is intended for motocross enthusiasts seeking serious and controlled preparation.
