The new billet flywheel has an ultra low drag fin design that will greatly reduce air drag on your racing engine, while still moving enough air for cooling. Less air drag on the flywheel means more power freed up throughout the power curve, especially on the top end. This flywheel is designed for oval track racing.
32° advance ignition angle can optimize combustion efficiency, increase low-speed torque and medium-high-speed horsepower, and do not need to adjust the ignition timing by yourself, and install and use it immediately, simplify the modification process.
The Billet process has higher structural strength and accuracy, can withstand higher speeds, reduce the risk of deformation or fracture during high-speed operation, ensure accurate flywheel dynamic balance, reduce engine vibration, and extend bearing and crankshaft life.




Joshua Jimenez –
The edges are finely chamfered without cutting hands, and the thickness of each heat dissipation fin is uniform. The dynamic balance is done extremely well, with no shaking during the 8000 rpm test. Black is anodized, not spray painted. It will not fade after long-term use and has an excellent texture
Sigourney Grant –
After replacing my GX160, the idle speed is more stable, the throttle linearity is improved, and the high-speed vibration is actually reduced. The black coating has a premium texture, the edge markings are easy to adjust, and the balance is first-class
Serena Underwood –
The black surface treatment is not only durable, but also has excellent heat dissipation performance. Running continuously for half an hour, the engine temperature is much lower than before
Amal Cherry –
After two months of violent driving every day, the black surface is still intact as new. Aluminum alloy has strong corrosion resistance, and there is no rust after riding in rainy weather. 32 degree ignition advance is recommended to be paired with a high-performance carburetor for a more aggressive power output!
