Glixal GY6 Variator Kit for 49cc–50cc Scooters — 6.5g Roller Weights, Complete CVT Replacement

The Glixal GY6 complete variator kit is a full replacement drive assembly for 49cc–50cc GY6 scooters and similar 4-stroke engines, supplied with 6.5g roller weights and all mounting components.

If your small-displacement scooter, moped or go-kart with a 139QMB/139QMA/147QMD family engine needs a reliable CVT overhaul, this kit provides the variator, back plate, drive face, rollers and ancillary parts to restore belt-driven performance. Built as a 100% new aftermarket assembly to match OEM dimensions, the kit fits many Chinese-made 4-stroke models and includes pieces required for immediate installation.

What exactly comes in the kit and what are the key dimensions?

This package contains the major variator components so you don’t have to source individual parts. All critical diameter and fit measurements are included to help confirm compatibility before purchase.

• Included parts: variator, variator back plate with slides, six 6.5g roller weights, drive face shaft, plastic variator fan, kick starter ratchet gear, and drive face gear.
• Outer variator diameter: 87.7 mm; boss bush size: 20 x 38 mm.
• Drive face gear outside diameter: 114 mm; drive face inner diameter: 13 mm; roller size: 16 x 13 mm.
• Weight tuning: 6.5 g rollers for balanced acceleration and top-end characteristics on 49cc–50cc setups.

Which engines and models will this variator kit fit?

The kit is designed for common GY6-type 4-stroke engines and a wide range of Chinese-made scooters, mopeds, ATVs and go-karts. Check your engine code and variator dimensions to ensure a correct match.

• Primary engine compatibility: 139QMB, 139QMA and 147QMD families.
• Displacement range: optimized for 49cc–50cc units, often compatible with certain 80cc–100cc applications when dimensions match.
• Common brands: fits many models from Taotao, Jonway, Roketa, Sunl, Tank, Peace, JMSTAR, JCL, Kazuma, ZNEN, Yiben, Benzhou and others.
• Vehicles: typical installs include scooters, small ATVs and go-karts that use the GY6-style CVT system.

How will installing this variator kit affect performance and maintenance?

Replacing a worn variator assembly restores smoother belt engagement, consistent acceleration and predictable top-end RPM behavior. Using the supplied 6.5 g rollers offers a moderate tuning point focused on reliable everyday performance rather than extreme race tuning.

• Benefits: more consistent CVT shifting, less belt slippage, improved throttle response after installation.
• Maintenance: replace rollers and inspect ramps and slides during belt service for best longevity.
• Tuning notes: changing roller weight alters shift RPM — 6.5 g is a stock-to-slightly-sport setup for many 50cc drives.

Are these parts OEM quality and easy to install?

The components are 100% new aftermarket parts manufactured to meet common OEM specifications and intended as direct service replacements. Installation requires basic CVT tools and some mechanical experience; fitting times vary by model but are typically straightforward for anyone familiar with scooter maintenance.

• Quality: aftermarket build engineered to OEM dimensions for fit and function.
• Tools: CVT puller/installer recommended, socket set, and torque wrench for secure assembly.
• Support: verify fit by comparing provided diameters and roller size with the worn variator before installation.

Who is this for: This Glixal variator kit is aimed at scooter owners, small-vehicle mechanics and DIY enthusiasts who need a complete CVT replacement for GY6-style 49cc–50cc engines. It’s especially useful if you want a single, ready-to-install package that restores drive performance on many Chinese-made scooters, mopeds, ATVs or go-karts without piecing together multiple parts.
