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

GY6 125/150cc 2000 RPM Clutch Springs. The clutch engages the rear wheel as engine speed rises; clutch springs set how early it grabs. Built to fit GY6, GY6 150cc (157QMJ).

A worn clutch shudders, slips or engages late. Stiffer springs make the clutch engage at a higher RPM for stronger launches. Confirm the clutch bell diameter and fitment for your engine.

Explosive Acceleration: 2000 RPM High-Performance Clutch Springs

Eliminate sluggish takeoffs and transform your scooter's low-end power delivery. These 2000 RPM Clutch Springs (Red) are engineered to delay clutch engagement until the engine reaches a higher power band. By allowing the engine to spin up to 2000 RPM before the clutch pads bite, you experience significantly faster off-the-line acceleration and improved throttle response.

Performance Advantages

• Aggressive Engagement: Raises RPM engagement above factory settings for a "racing" feel and instant power.
• High-Tensile Steel: Manufactured from premium spring steel to resist heat-fade and maintain consistent tension under racing conditions.
• Optimized for Tuning: The ideal upgrade for scooters with performance exhausts, big bore kits, or variator upgrades.
• Direct OEM Replacement: Designed to fit perfectly within the stock GY6 clutch carrier.
