UMA Racing Super Light Ignition Rotor for Yamaha MT/ R15 V3/ V4 - 02I00270

Uma Racing Super Light Ignition Rotor | Yamaha R15 V3 / Y15ZR (02I00270)

Optimize your engine's rotational mass and responsiveness with the Uma Racing Super Light Ignition Rotor (Magneto). Designed to "Reveal the True Performance," this race-proven component is a key upgrade for riders seeking quicker acceleration and sharper engine dynamics.

Key Features

• Improve Throttle Response: By reducing the rotational weight of the crankshaft assembly, the engine can climb RPMs more rapidly, leading to significantly sharper throttle response.

• Improve Acceleration: The lightweight design allows for faster energy transfer, resulting in improved off-the-line and mid-range acceleration.

• Race Proven: Engineered for competitive use, ensuring reliability and performance under high-RPM racing conditions.

• Lightweight Construction: Precision-machined to be substantially lighter than the stock ignition rotor while maintaining structural integrity.

Technical Specifications

Why Upgrade to the Super Light Ignition Rotor?

The Uma Racing Magneto (02I00270) is a highly effective modification for extracting more performance without altering engine displacement. In high-performance builds—such as those utilizing the Uma Racing 63mm Ceramic Block or Hyper Clutch—reducing parasitic drag on the engine is essential. This rotor ensures that more of your engine's power is dedicated to forward motion rather than spinning heavy internal components.
