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.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this variator kit change my scooter's acceleration and throttle feel?\u003c\/h3\u003e\n\u003cp\u003eFitting 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSmoother pulley engagement for reduced lag\u003c\/li\u003e\n  \u003cli\u003eLighter 13g rollers shorten time-to-peak RPM\u003c\/li\u003e\n  \u003cli\u003eImproved belt contact for steadier power transfer\u003c\/li\u003e\n  \u003cli\u003eCompatible with stock and mildly modified engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these parts fit my GY6 125cc or 150cc (152QMI \/ 157QMJ) engine?\u003c\/h3\u003e\n\u003cp\u003eThe kit is tailored to the common Chinese 4-stroke GY6 variants listed: 152QMI and 157QMJ.
