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.
Comprehensive Fitment Guide
This secondary sheave (SKU: 1200-1268) is a direct performance upgrade for 50cc Honda liquid-cooled 4-stroke engines:
| Model Series | Compatibility Note |
|---|---|
| Honda Ruckus (NPS50) | 2003 – 2026+ (All GET Models) |
| Honda Metropolitan (CHF50) | 2002 – 2009 (GET Engine Only) |
Technical Specifications
- Groove Profile: Straight-Cut (Performance Linear)
- Material: Hardened Carbon Steel Alloy
- O-Rings: Pre-installed High-Temp Rubber
- Compatibility: Works with stock, NCY, or Polini torque springs
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.
