Glixal variator kit for GY6 125cc/150cc scooters — ATKS-042 with 13g roller weights, precision machined variator

Glixal ATKS-042 is a high-performance variator kit engineered to improve acceleration and throttle response for Chinese GY6 125cc/150cc 4-stroke scooter, moped and ATV engines.

This complete front-clutch variator kit includes a precision-machined variator, matching bush, and a set of 13g roller weights sized 18x14 mm. It’s built to fit common 152QMI and 157QMJ engine variants (GY6-style 125cc and 150cc) and replaces worn or stock drive components to restore or tune belt-driven CVT performance.

How will this variator kit affect acceleration and throttle response?

Swapping to the Glixal ATKS-042 with 13g rollers shifts the variator’s engagement curve, producing crisper launch acceleration and more immediate throttle feel without changing the engine internals. Riders often notice quicker takeoffs and reduced lag during city riding.

• 13g roller weights tailor the RPM rise for faster engagement
• Precision variator faces deliver consistent belt contact
• Reduced slippage at low speed improves urban acceleration

Will this fit my scooter’s GY6 125cc or 150cc engine?

The kit is designed specifically for Chinese 4-stroke GY6-style engines using 152QMI and 157QMJ specifications. Confirm fit by checking variator inner diameter and bush dimensions against your machine before purchase.

• Variator outer diameter: 115 mm for correct belt profile
• Inner diameter: 24 mm to match standard GY6 crank shafts
• Bush size: O/D 24 mm, I/D 15 mm, length 51.5 mm — matches many GY6 setups

What do I need to know about the roller weights and their sizing?

The kit comes with 13g rollers, each measuring 18x14 mm, which balance acceleration and top-end potential for street use. Changing roller mass alters how quickly the variator moves through its ratio range, so 13g is a common middle ground for improved city performance without extreme gearing.

• Roller weight: 13 grams per roller for moderate acceleration bias
• Roller dimensions: 18 x 14 mm to fit the variator’s weight slots
• Set is compatible with standard GY6 variator housings that accept this roller size

How difficult is installation and what should I check during fitting?

Installation is straightforward for anyone comfortable with basic scooter maintenance and variator tools. Remove the front clutch cover, replace the variator and bush, insert the rollers correctly, and re-torque to factory specifications; a torque wrench and variator puller will make the job easier and safer.

• Requires removal of belt and front clutch cover for access
• Use a variator puller and torque wrench for proper installation
• Inspect belt condition and clutch ramp surfaces while installed

Who is this for: The Glixal ATKS-042 variator kit is aimed at riders of Chinese GY6 125cc and 150cc scooters, mopeds, and light ATVs who want sharper low- to mid-range response and a reliable, direct-fit replacement for worn variator components. It’s well suited for commuters, tuning enthusiasts seeking a modest performance tweak, and mechanics performing routine drive-train maintenance. Before ordering, confirm your engine model (152QMI or 157QMJ) and verify variator/bush dimensions match your machine to ensure compatibility.
