HOT CAMS Camshaft - Stage 1 (Ref. 4131-1) for Yamaha YFM700/R Raptor

Specifically designed for the Yamaha YFM700 Raptor quad, this HOT CAMS Stage 1 camshaft provides an accessible optimization for riders and tuners looking to enhance engine character without completely transforming the machine. Developed on test benches and validated in racing by teams, this profile remains compatible with the original configuration: it increases torque and power without any additional modifications needed, making it ideal for a light preparation aimed at recreational use or sporty trail riding.

• Stage 1: improves responsiveness and torque availability, easy installation for a more pronounced engine feel.
• Stage 2: designed for more advanced modifications; requires other changes (high compression pistons, larger carburetor...) to fully utilize the profile.
• Stage 3: intended for extreme uses (supermoto, increased displacement) and to be paired with the original valve springs.

Installation should be performed by a qualified person with the appropriate tools. Two complete sets of shim kits are provided to allow for precise valve clearance adjustment and optimal cam timing.

Compatibility: YAMAHA YFM 700 RAPTOR (2020-2021) and Special Edition variants indicated for this reference.
