Why Choose the Uma Racing Decompression Timing Gear?

The Uma Racing 02TG0070 is an essential upgrade for any Yamaha Aerox 155 owner who has moved to a high-compression setup, such as the Uma Racing 63mm X PRO Piston and Block Kit. High-compression engines can be notoriously difficult to start, often leading to burnt-out starter motors or drained batteries. This gear solves that issue by mechanically venting excess pressure during the start-up phase while providing the easy adjustments necessary to dial in your engine's powerband for maximum efficiency.
