Like other \u003ca href=\"\/collections\/gy6-50cc-parts\"\u003eGY6 50cc scooter parts\u003c\/a\u003e, they influence how the engine delivers power and how quickly the scooter picks up speed, so they matter for keeping your ride performing well.\u003c\/p\u003e\u003ch3\u003eHow Roller Weights Work\u003c\/h3\u003e\u003cp\u003eRoller weights sit inside the variator assembly that forms part of the scooter's drive system. As engine speed changes, they shift the gear ratio, which gives a smooth pickup and better torque. Swapping out weights that are worn or damaged can bring back lost performance and help the scooter run efficiently again.\u003c\/p\u003e\u003ch3\u003eFitting Notes\u003c\/h3\u003e\u003cp\u003eFitting roller weights is a simple job that usually needs only basic hand tools. You'll need to take off the variator cover to reach the weights. Consider replacing them if the scooter feels slow to accelerate or delivers power unevenly, since those are common signs the weights have worn down.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 16x13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GY6 50cc (139QMB) engines; Vespa, Piaggio, Honda, Kymco and other listed 50cc scooters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 139QMB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Models\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVespa ET2 50 (97-05 R)\u003c\/li\u003e\n\u003cli\u003eVespa LX 50 (05-15 R)\u003c\/li\u003e\n\u003cli\u003eVespa S 50 4T\/4V (08-15 R)\u003c\/li\u003e\n\u003cli\u003ePiaggio Typhoon 50\/SE (06 R)\u003c\/li\u003e\n\u003cli\u003ePiaggio Typhoon 50 2T (10-inch wheels) (07-09 R)\u003c\/li\u003e\n\u003cli\u003eBaja SC50\u003c\/li\u003e\n\u003cli\u003eHonda Dio\u003c\/li\u003e\n\u003cli\u003eHonda Elite 50\u003c\/li\u003e\n\u003cli\u003eHonda Ruckus 50 (NPS50)\u003c\/li\u003e\n\u003cli\u003eKymco Filly 50\u003c\/li\u003e\n\u003cli\u003ePanterra Fusion 50cc\u003c\/li\u003e\n\u003cli\u003ePanterra Retro 50cc\u003c\/li\u003e\n\u003cli\u003eQMB139 50cc\/49cc\u003c\/li\u003e\n\u003cli\u003eQingqi QM50QT-6V\u003c\/li\u003e\n\u003cli\u003eSUNL SL50QT-16\u003c\/li\u003e\n\u003cli\u003eTank Classic 50QT-6\u003c\/li\u003e\n\u003cli\u003eVarious unlisted makes\/models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eChoosing a weight:\u003c\/strong\u003e Pick the weight that matches your engine's 139QMB clutch, then choose the gram rating that fits your riding style.
