Yamaha Zuma 50 2T Performance Super Transmission Kit

Performance Super Transmission Kit for Yamaha Zuma 50 2T and Related Models

This CVT upgrade kit is built for the Yamaha Zuma 50 2T and other scooters that run horizontal Minarelli engines. It contains the parts you need to sharpen throttle response and acceleration. If you are replacing worn transmission components, this kit is a practical option. You can also browse our Yamaha Zuma scooter parts for other upgrades that may help ride quality.

What the Kit Contains

The package includes a full variator assembly, a lightweight outer drive face, and a Gen 4 racing clutch built for stronger grip. It also has a PTFE-coated racing clutch bell, which helps with heat management, along with a dual-range secondary slider. Three sets of roller weights (5g, 6g, and 7g) let you adjust the tune. A 1500 RPM compression spring is included to firm up secondary engagement.

Power Delivery Notes

The dual-range secondary slider is meant to reduce flat spots, giving a more even acceleration curve. The bronze anodized drive face is very light, which adds to how the scooter responds. For the best outcome, pair the kit with a good-quality drive belt and apply a thin coat of light Molybdenum grease to the clutch sheave slider pins.
