NCY Performance Super Transmission Set- Yamaha Zuma 50 2T

Eliminate the Mid-Range Bog: NCY Super Transmission Set

The NCY Super Transmission Set is the gold standard for Yamaha 2-stroke (2T) tuning. This comprehensive "Super Trans" kit replaces your restrictive factory CVT components with balanced, ultralight racing parts designed to deliver explosive acceleration and a higher top-end ceiling.

The Competitive Edge: Dual-Range Tuning

• Secondary Slider Upgrade: Includes the NCY secondary sliding sheave with optimized angles to eliminate the "flat spot" in power delivery common on stock Zuma/Jog pullies.
• PTFE Friction Reduction: The clutch bell features a state-of-the-art Polytetrafluoroethylene (PTFE) coating for superior heat dissipation and consistent grip under racing conditions.
• Balanced Weight Tuning: Comes with three full sets of 15x12 roller weights (5g, 6g, and 7g), allowing you to precisely tune your CVT for either high-torque climbing or maximum MPH.
• Increased Spool Speed: The ultralight drive face and large-shoe racing clutch allow the engine to reach its powerband faster than heavy OEM cast parts.

• • NCY CVT variator
