Glixal Variator Kit for GY6 125–150cc ATKS-042 — 13g Rollers, 115mm Outer Variator

Designed for GY6-style 4-stroke engines (models 152QMI and 157QMJ), the Glixal ATKS-042 kit replaces the factory front clutch components with precision-machined parts to improve acceleration feel, throttle response and top-end gearing flexibility. The assembly includes a 115mm outer variator, matching 24mm inner bore, and a set of 13g roller weights sized 18×14 mm — all sized to the dimensions commonly used on Chinese 125cc and 150cc applications.

How does this variator kit affect acceleration and throttle response?

The kit alters how the CVT pulley changes ratio under load, giving quicker engine rev transitions and a livelier launch compared with worn or stock components. With properly matched 13g rollers, the variator shifts more predictably and reduces lag when you twist the throttle.

• 13g roller weights tuned for improved mid-range pickup
• Smoother ramp profile thanks to precise variator bore sizing
• Reduced slippage from new clutch face engagement

Will the Glixal ATKS-042 fit my scooter, and what are the exact dimensions?

The kit fits Chinese GY6 4-stroke engines designated 152QMI and 157QMJ commonly found in many 125cc and 150cc scooters, mopeds and some ATVs. Key dimensions are engineered to match standard GY6 variator interfaces for straightforward swap-in installation.

• Outer variator diameter: 115 mm
• Inner variator diameter (bore): 24 mm
• Bushing outside/inside diameter: O/D 24 mm, I/D 15 mm, length 51.5 mm
• Roller weight size: 18×14 mm; weight: 13g each

What installation and maintenance should I expect?

Installation typically requires removal of the CVT cover, stock variator and roller weights, then assembly of the Glixal components in the reverse order. Routine checks and occasional cleaning of the variator face and rollers keep performance consistent over time.

• Requires basic hand tools and a service manual reference
• Inspect belt and clutch shoes while installing for best results
• Clean pulley surfaces and lightly lubricate bushing per manufacturer guidance

Can this kit be used for tuning or performance upgrades?

The Glixal ATKS-042 is compatible with common bolt-on upgrades and can be part of broader tuning packages; changing roller weight or belt size can further tailor acceleration or top speed. Match any additional changes (exhaust, intake, ECU) with roller weight and final drive adjustments to maintain driveability.

• Works well with performance belts and clutch shoe upgrades
• Swapping roller weights alters shift points and acceleration character
• Best combined with belt and clutch inspection for consistent results

Who is this for? The Glixal ATKS-042 variator kit is aimed at scooter, moped and ATV owners running GY6 152QMI/157QMJ 125cc–150cc engines who want a reliable, direct-replacement upgrade for sharper throttle response and improved CVT behavior. It suits DIY mechanics and professional shops looking for precise dimensions (115 mm outer, 24 mm bore, 13g rollers) and durable parts to replace worn factory components or tune the transmission response for daily rideability and spirited street use.
