GY6 125/150cc 2000 RPM Clutch Springs (Standard)

GY6 125/150cc 2000 RPM Clutch Springs. The clutch connects the rear wheel once engine speed climbs; the clutch springs determine the RPM at which that connection happens. Made for GY6, GY6 150cc (157QMJ).

A worn clutch can shudder, slip, or grab later than it should. Firmer springs make the clutch engage at a higher RPM, which gives stronger starts. Check the clutch bell diameter and fitment for your engine before ordering.

Quick Off-the-Line Response: 2000 RPM Performance Clutch Springs

If your scooter feels slow to pull away, these 2000 RPM Clutch Springs (Red) change when the clutch takes hold. The clutch pads don't bite until the engine reaches about 2000 RPM, so the scooter gets moving faster from a stop and responds more quickly to the throttle.

Key Features

• Sharper Engagement: Engagement RPM is set higher than the factory setting, for a more aggressive, racing-style response.
• High-Tensile Steel: Made from quality spring steel that holds its tension under heat and hard use.
• Built for Tuned Setups: A good match for scooters with performance exhausts, big bore kits, or variator upgrades.
• Drop-In Replacement: Designed to sit in the stock GY6 clutch carrier without modification.

Tech Tip: Stiffer clutch springs make the engine work harder before the clutch engages. On a stock scooter, the 2000 RPM set can feel quite aggressive. For a gentler change on a daily commuter, the 1000 RPM or 1500 RPM springs are a better fit.
