UMA Racing Cam Stopper - Yamaha T135/R15/T150/Fz150i

The UMA Racing Cam Stopper is a heavy-duty, reinforced camshaft retainer plate. It replaces the factory-installed plate to prevent the camshaft from moving or slipping out of place at high engine speeds.

Core Function & Benefits

• Prevents Engine Failure: Stock plates often crack under high RPM pressure, which displaces the camshaft and causes catastrophic internal engine damage.
• Stabilizes Valve Timing: Keeps the camshaft locked firmly into its seated position, preserving precise valve duration and performance during aggressive riding.
• High-Rigidity Material: Constructed entirely from high-grade stainless steel to ensure maximum structural strength and wear resistance.
