Bigger is Better: SSP-G 115mm GY6 Performance Variator
Upgrade your GY6 drivetrain with the SSP-G 115mm Performance Variator. Engineered for 125cc and 150cc GY6 engines, this variator uses an oversized 20x12mm roller weight configuration — moving away from the restrictive stock 18x14mm geometry to allow greater roller travel, a broader gear ratio, punchier acceleration, and higher top speed potential. Comes pre-loaded with 12g roller weights. SKU: 169-581.
Key Features
- 20x12mm weight geometry — larger roller footprint allows the variator to open wider and close tighter than standard units
- 115mm oversized diameter — belt travels further out the pulley face, effectively increasing your top gear for higher cruising speeds
- Precision machined ramps — ultra-smooth roller tracks reduce friction and eliminate stepping for seamless RPM transitions
- Includes 12g roller weights (set of 6) — a versatile sport tune suitable for most 150cc street applications
Pairing tip: For best results, pair with a matching 115mm drive face and an 842-20-30 drive belt to ensure consistent belt surface across the entire pulley system.
