CAM GEAR ADJUSTABLE – YFZ450R / YFZ450 / YZ450F

Absolute timing precision. Maximum performance on any terrain.

Force Parts Adjustable Cam Gears are engineered for engines that require precise timing control to extract maximum performance. With a ±16° adjustment range in precise 2° increments, you can fine-tune power delivery to match your riding style, terrain or competition setup, without replacing the complete camshaft assembly.

Manufactured from heat-treated 8620 steel, these gears offer exceptional durability and completely eliminate the possibility of slippage, even in high-compression or high-RPM engines.

What does an adjustable cam gear do?

It lets you precisely adjust when the intake and exhaust valves open and close. That timing directly affects peak power, torque, throttle response and high-RPM stability, and allows fine-tuning for different tracks or internal engine modifications.
