Yamaha Rhino 660 Camshaft - Hot Cams - Stage 1 - `04-`07. This Stage 1 camshaft is designed to give your Rhino predictable, usable power gains while retaining stock reliability and an easy installation.

Designed and dyno-proven in the USA using state-of-the-art valvetrain software, the Hot Cams Stage 1 camshaft for the Yamaha Rhino/YFM 660 series offers a conservative performance upgrade. CNC-machined from 8620 billet, case-hardened steel, this camshaft provides precise lobe profiles for consistent valve timing and long service life. Stage 1 tuning focuses on improved low- to mid-range torque and a reported 5–10% power increase when matched with compatible engine and intake/exhaust components. The unit requires no core exchange and is offered in multiple stages for owners who may want to move to Stage 2 or 3 later.
