NCY Anti-Torsion Spring Seat - Zuma / Jog 50, Minarelli 2T
Description
NCY anti-torsion secondary spring seat for Yamaha Zuma 50, Jog, and Minarelli 1E40QMB-based CVT transmissions — a steel cylindrical cup with an integrated ball bearing race that sits between the contra/torque spring and the rear clutch pulley.
The ball bearings allow the spring to rotate freely as it compresses, eliminating spring bind that causes flat spots and inconsistent shifting. Includes steel cup, bag of steel ball bearings, and bearing race. SKU: 1200-1196 | MPN: 211A08JOG.
Key Features:
- Steel cylindrical cup with integrated ball bearing race — allows contra spring to rotate freely during compression
- Includes bag of small steel ball bearings and two black rubber seals to retain bearings in the cup
- Eliminates spring bind that causes flat spots and inconsistent CVT shifting behavior
- Keeps CVT in the powerband longer — improves throttle response and mid-range acceleration
- Recommended upgrade whenever replacing the contra/torque spring | SKU: 1200-1196 | Made in Taiwan by NCY
