UMA Racing Timing Chain Gear for Yamaha MT/ R15 V3/ V4 - 02TG0040

Uma Racing Decompression Timing Gear | Yamaha R15 / Y16ZR (02TG0040)

The Uma Racing Decompression Timing Gear is a specialized performance component designed to "Reveal True Performance" while ensuring your high-performance engine remains easy to start. It is specifically engineered to handle the increased internal pressures of modified, high-compression (CR) engines.

Key Features

• Pressure Reducing Mechanism: Incorporates a system that vents excess cylinder pressure during the starting phase for a smooth and easy engine start-up.

• Reduced Starter Strain: Significantly lowers the mechanical stress on the starter motor and battery, preventing premature wear on the electrical start system.

• Adjustable Timing Gear: Features an adjustable design that allows tuners to precisely dial in valve timing for optimal power delivery.

• High-Grade Construction: Built from durable materials to maintain timing accuracy and withstand high-RPM racing conditions.

• Essential for High CR Engines: Labeled as a unique and necessary component for motorcycles with high-compression engine builds.

Why Choose the Uma Racing Decompression Gear?

Standard timing gears lack the mechanical assistance needed to turn over engines with aggressive compression ratios, such as those using the Uma Racing 63mm X PRO Piston. The 02TG0040 gear solves this by reducing the initial resistance, protecting your starter motor from burning out while providing the flexibility to adjust your timing for maximum performance gains.
