NCY Secondary Spring Seat; Zuma 50T, Jog 50, Minarelli 50

Smooth Shifting: NCY Anti-Torsion Secondary Spring Seat

Eliminate transmission "bind" and inconsistent shifting with the NCY Secondary Spring Seat. Designed for Yamaha Zuma and Jog (Minarelli) based engines, this high-quality upgrade acts as a friction-reducing interface between your torque spring and the clutch pulley. By allowing the spring to twist freely as it compresses, this seat ensures your CVT stays in the powerband longer and responds instantly to throttle inputs.

Technical Performance Features

• Anti-Torsion Design: Prevents the torque spring from "locking" or binding during compression, leading to a more linear and predictable shifting curve.
• Reduced Internal Friction: The smooth, polished surface allows the spring to rotate independently of the pulley, reducing wear on the spring ends and the clutch assembly.
• Precision NCY Engineering: Machined to exacting tolerances for a perfect drop-in fit on factory and performance Minarelli-style rear pulleys.
• Improved Throttle Response: By removing mechanical resistance in the rear pulley, your transmission can downshift faster when you roll on the throttle for mid-range acceleration.

Mechanic's Note: This is a highly recommended "while you're in there" upgrade whenever you are changing your Torque Spring. Spring bind is the #1 cause of "flat spots" in scooter acceleration. For the best results, ensure your rear pulley sheaves are clean and lightly greased with high-temp CVT grease before reassembling the clutch stack.
