They are a newer take on \u003ca href=\"\/collections\/scooter-variators-rollers\"\u003escooter variators \u0026amp; roller weights\u003c\/a\u003e, using a sliding design that changes gear ratios more smoothly. Compared with standard roller weights, this can support quicker acceleration, higher top-end speed, and a longer service life.\u003c\/p\u003e\u003ch3\u003eA Different Sliding Design\u003c\/h3\u003e\u003cp\u003eStandard roller weights move by rolling, while Dr. Pulley's version moves by sliding. That change cuts down on wear in the transmission, including when the scooter is running at high speed. The gear ratio holds up over time, which helps the drivetrain last longer.\u003c\/p\u003e\u003ch3\u003eWhat You Gain\u003c\/h3\u003e\u003cp\u003eBecause these sliding roller weights widen the usable range of gear ratios, they help with acceleration and pickup from speed. Riders wanting more top-end speed from their scooter will find them a good fit. The weights also compensate for wear automatically, so they keep adjusting and working properly as they age.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 21x15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Includes:\u003c\/strong\u003e 6 weights\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatent Number:\u003c\/strong\u003e 7,276,004\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Vespa GT 200, GTS 250 and GTS 300 (21x15 sliding roller weights)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVespa GT 200\u003c\/li\u003e\n\u003cli\u003eVespa GTS 250\u003c\/li\u003e\n\u003cli\u003eVespa GTS 300\u003c\/li\u003e\n\u003cli\u003ePiaggio scooters (sized 21x15 Dr. Pulley weights)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Pick the 12G or 17G weight from the drop-down menu.
