Glixal GY6 High-Performance Racing Clutch Assembly with Bell — 22-Spline 49/50/100cc, 2000 RPM Springs

Glixal GY6 Racing Clutch Assembly with Bell is a drop-in high-performance clutch kit for 49cc, 50cc and 100cc GY6-based scooters and minibikes designed to improve engagement and handle higher RPMs.

This clutch assembly pairs a precision-machined bell with a complete clutch shoe assembly and hardware to upgrade small-displacement GY6 engines. Built for riders seeking crisper throttle response, stronger engagement and compatibility with common GY6 drivetrains, the kit includes 22-spline taper fitment, a pulley and needle bearing designed for durability, and 2000 RPM clutch springs to shift engagement characteristics closer to performance setups.

What does this clutch kit include and how does it fit my engine?

The package contains the clutch bell, clutch shoe assembly, a pulley with HK172518RS needle bearing, and clutch springs rated at 2000 RPM. It is made to match GY6 housings that accept a 22-spline bell and a 12mm inner-diameter bearing for the shoe assembly.

• 22-spline inside clutch bell for direct fit on GY6 output shafts
• Bell outer diameter: 117mm; pulley outer diameter: 119mm
• Included pulley needle bearing: HK172518RS for smooth rotation
• Clutch shoe bearing ID: 12mm (fits 6901RS style)

How will this upgrade affect clutch engagement and performance?

The included 2000 RPM springs raise the engagement threshold so the clutch transfers power later than many stock setups, giving a firmer takeoff and more aggressive acceleration under load. This alters the powerband feel and is commonly paired with other small-engine performance parts to maximize effect.

• 2000 RPM springs increase engagement RPM for sharper throttle response
• Precise pulley and needle-bearing reduce parasitic drag for consistent spin
• Larger pulley OD improves belt seating and reduces slippage risk
• Note: actual gains depend on engine tuning, variator, belt condition and weight

Is this clutch durable and what materials or tolerances matter?

The assembly uses machined bell geometry and standard high-quality bearings to withstand the higher RPMs associated with racing or upgraded engines. Bearing types and spline count are specified to ensure longevity when installed and maintained correctly.

• Machined 117mm OD bell for balanced rotation under load
• HK172518RS needle bearing in pulley for reduced wear and heat
• 6901RS-compatible 12mm ID bearing in the shoe assembly for secure fitment
• Regular inspection and correct installation torques extend service life

Who is this for? The Glixal GY6 Racing Clutch Assembly with Bell is aimed at scooter and minibike owners with 49cc, 50cc or 100cc GY6-pattern engines who want a robust clutch upgrade for sportier acceleration or competition use. It fits DIY mechanics, racers and tuners who understand that optimal results depend on complementary parts—such as variator selection, belt condition and engine tuning—and who are prepared to match the clutch to their overall drivetrain setup. Avoid if you need stock-like low-speed smoothness or if your engine’s gearbox uses a different spline count or bearing size.
