Unlike traditional round roller weights, these patented sliding rollers allow your variator to open further for higher top speeds and faster mid-range acceleration. The unique composite nylon material is designed for low friction and high-temperature resistance, significantly outlasting standard weights by preventing the flat spots that typically hinder performance over time. Key Benefits Increased Top Speed: Unique shape allows the belt to ride higher in the variator. Anti-Flat Spot Technology: Sliding motion eliminates the uneven wear common in round rollers. Self-Lubricating Material: Long-wearing nylon composite reduces friction and heat. Precision Tuning: Available in multiple gram weights to customize take-off and top-end power. Technical Specifications Dimensions: 20mm (diameter) × 15mm (width) Quantity: 6 pieces per set Material: High-resistance SL-composite nylon Fitment: Fits Honda 110–150cc scooters and GY6 \"B-Case\" engines or performance builds with modified variators... always measure to confirm! Brand \/ Engine Type Compatible Models Honda PCX 125, PCX 150, Navi 110, SH 125, SH 150 Genuine Blur 220i GY6-B \/ ZNEN 1P61QMK Other GY6 Performance builds Modified Variators with 20x15mm weights Fitment note: Standard GY6 (125cc\/150cc): The vast majority of Standard GY6 engines (found in brands like TaoTao and Ice Bear) use 18x14mm rollers. If you try to put 20x15mm weights in a standard variator, they physically won't fit or will bind immediately. GY6-B \/ ZNEN Variants: Some high-end Chinese scooters (often manufactured by ZNEN) use a \"B-Case\" engine or a modified variator that do accept these larger 20x15mm weights. Measure to confirm! Installation Tip: For optimal results, ensure your variator ramps are clean and free of debris before installation. Note: Performance upgrades are considered racing parts and are not covered by warranty.
