Glixal GY6 125–150cc Variator Kit ATKS-042 — 13g Roller Weights, 115mm High-Performance

Glixal ATKS-042 is a high-performance variator and roller weight kit engineered to upgrade GY6-style 125cc–150cc Chinese 4-stroke scooter, moped and ATV front-clutch systems for crisper acceleration and more consistent top-end rev response.

This kit replaces the stock variator components on 152QMI and 157QMJ engines with precision-matched parts designed for racing-oriented tuning. The assembly pairs a 115mm outer-diameter variator with 13g roller weights and hardened bushings to optimize belt engagement profiles and deliver smoother throttle transitions under load. Ideal for riders tuning for quicker spool-up, improved midrange power delivery or a more responsive CVT feel, the Glixal ATKS-042 is intended for performance use on compatible Chinese GY6 platforms.

How will this variator kit change my scooter's acceleration and throttle feel?

Fitting the ATKS-042 alters the CVT shift curve by using lighter, consistent 13g rollers and a precisely machined variator face. Expect faster ramping of the pulley, resulting in more immediate acceleration from standstill and sharper mid-throttle response without altering engine internals.

• Smoother pulley engagement for reduced lag
• Lighter 13g rollers shorten time-to-peak RPM
• Improved belt contact for steadier power transfer
• Compatible with stock and mildly modified engines

Will these parts fit my GY6 125cc or 150cc (152QMI / 157QMJ) engine?

The kit is tailored to the common Chinese 4-stroke GY6 variants listed: 152QMI and 157QMJ. Key dimensions match OEM mounting points and belt geometry, but confirm variator inner/outer diameters and bushing sizes against your current components before purchase.

• Variator outer diameter: 115mm to fit standard housings
• Inner diameter: 24mm for drive shaft compatibility
• Bushing O/D 24mm, I/D 15mm, length 51.5mm for proper fitment
• Roller size 18x14mm — check drum clearance

What installation and maintenance should I expect with this racing variator?

Installation is similar to most GY6 variators but requires basic mechanical tools and some experience with CVT removal. After fitting, check belt wear, torque specs, and roller seating. Periodic inspection ensures optimal performance and longevity.

• Use correct torque on variator nut and clutch assembly
• Inspect roller surfaces and replace if glazed or flattened
• Replace drive belt when installing variator for best results
• Verify free movement of sliders and clean mating surfaces

What concrete parts and measurements are included in the kit?

The Glixal ATKS-042 comes as a set of performance-focused components sized for precise installation. The supplied rollers and bushing dimensions were chosen to tune the CVT ratio curve toward quicker rev climb while maintaining compatibility with common GY6 builds.

• Variator outer diameter: 115mm
• Variator inner diameter: 24mm
• Bush dimensions: O/D 24mm, I/D 15mm, length 51.5mm
• Roller set: 13g each, size 18x14mm

Who is this for: The Glixal ATKS-042 suits riders who want a reliable, plug-in performance upgrade for Chinese GY6 125cc–150cc scooters, mopeds or ATVs. It’s well matched to hobbyist tuners and weekend racers seeking improved throttle response and acceleration without extensive engine modification. If you run a 152QMI or 157QMJ powerplant and want a straightforward variator swap to sharpen driveability, this kit provides the dimensional compatibility and roller selection commonly used for sportier CVT behavior.
