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.
This secondary sheave (SKU: 1200-1268) is a direct performance upgrade for 50cc Honda liquid-cooled 4-stroke engines:
Mechanic's Tuning Note: This is an essential upgrade for "stretched" Ruckus builds or bikes running Polini variators. For the smoothest operation, ensure the internal guide pins are lubricated with high-temperature Moly CVT grease during assembly to prevent heat-related binding.
