Standard spring seats allow the torque spring to twist against the clutch pulleys, causing inconsistent shifting and dead spots in acceleration. This NCY upgrade uses a ball-bearing track so the spring rotates freely — smoother back-shifting, reduced friction, and snappier throttle response. Compatible with stock and aftermarket torque springs. Made in Taiwan by NCY. \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDesign: needle\/ball bearing sandwich plate\u003c\/li\u003e\n\u003cli\u003eConstruction: high-tensile steel races\u003c\/li\u003e\n\u003cli\u003eFits: 107mm or smaller clutch diameter\u003c\/li\u003e\n\u003cli\u003eCompatible with stock and aftermarket torque springs\u003c\/li\u003e\n\u003cli\u003eWeight: 0.1 lbs\u003c\/li\u003e\n\u003cli\u003eSKU: 1200-1253\u003c\/li\u003e\n\u003cli\u003eMade in Taiwan by NCY\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCompatible Engines \/ Models:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e139QMB \/ QMB139:\u003c\/strong\u003e all Chinese 50cc 4-stroke scooters (TaoTao, Wolf, etc.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHonda Dio \/ Elite 50:\u003c\/strong\u003e AF16, AF18, AF25 engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKymco \/ SYM 50cc:\u003c\/strong\u003e ZX50, Agility 50, Fiddle 50\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eMechanic's note:\u003c\/strong\u003e One of the best \"secret\" mods for the 139QMB engine.
