GY6 Performance CVT Transmission Kit 125cc-170cc

Looking for the best performance upgrade without going into the engine? This GY6 CVT transmission kit transforms how your scooter accelerates, shifts, and carries speed — smooth, fast, and way more responsive than stock 🏁⚙️

• ⚡ Faster acceleration and higher top speed
• 🎯 Smoother shifting and throttle response
• 🪶 Lightweight rotating parts for better efficiency

The Details ⚙️

This GY6 performance transmission kit includes everything needed to wake up your scooter’s drivetrain. The lighter components help your engine spool up faster, while the upgraded clutch and variator provide a stronger bite and more consistent engagement across the RPM range.

The clutch shoes are larger for better grip, the variator is Teflon coated for durability, and the clutch bell is designed for improved cooling. The compression spring seat also uses a roller-bearing upgrade — a newer design that gets rid of friction and makes shifting smoother (shown in the video above).

If you’re looking for a dramatic improvement in acceleration, mid-range pull, and riding feel — without tearing open the engine — this kit is one of the highest value upgrades you can do 💯
