NCY Secondary Sliding Sheave Clutch Pulley: Honda Ruckus GET

Eliminate Flat Spots: NCY Performance Secondary Sheave Unlock smoother power delivery and more responsive downshifting with the NCY Secondary Sliding Sheave Assembly . Specifically engineered for the Honda Ruckus (GET engine), this high-performance "Torque Driver" replaces the restrictive, curved-groove factory rear pulley. By utilizing optimized ramp angles, it allows the CVT to transition through gear ratios more fluidly, keeping you in the powerband during hill climbs and high-speed cruising. Technical Performance Features Straight-Cut Torque Grooves: Unlike the curved stock grooves that cause "shifting lag" or a mid-range bog, these linear paths provide consistent belt tension and a predictable shift curve for better engine response. Dual-Slit Tuning: Features two sets of guide pin slits with varying angles, allowing you to fine-tune your acceleration profile based on your specific rider weight and performance goals. Heat-Treated Steel Construction: Manufactured from high-tensile steel to resist the internal grooving and "belt-step" wear common in high-mileage or modified CVT systems. Complete Pre-Sealed Assembly: Includes pre-installed high-temperature O-rings and oil seals, ensuring a leak-free, "bolt-on" installation right out of the box.
