It engages 1,500–2,000 RPM higher than a stock clutch, allowing the engine to build more power before the clutch locks in — resulting in faster take-off from stops and more aggressive acceleration. Kevlar-reinforced friction pads and red performance springs. Black anodized aluminum construction with Naraku logo on each shoe. Fits Genuine Buddy 50, Roughhouse 50, Honda Jog 2T, Honda Dio 2T, and all 139QMB-engined scooters.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e3-shoe design with Kevlar-reinforced friction pads\u003c\/li\u003e \u003cli\u003eEngages 1,500–2,000 RPM higher than stock for faster take-off\u003c\/li\u003e \u003cli\u003eRed performance springs — higher engagement RPM than stock springs\u003c\/li\u003e \u003cli\u003e107mm outer diameter\u003c\/li\u003e \u003cli\u003eBlack anodized aluminum construction\u003c\/li\u003e \u003cli\u003eFits 139QMB 50cc 4T and compatible 2T engines\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eSpecifications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eOuter Diameter: 107mm\u003c\/li\u003e \u003cli\u003eShoes: 3-shoe\u003c\/li\u003e \u003cli\u003eFriction Material: Kevlar-reinforced\u003c\/li\u003e \u003cli\u003eEngagement: 1,500–2,000 RPM above stock\u003c\/li\u003e \u003cli\u003eApplication: 139QMB 50cc 4T and compatible 2T engines\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCompatible Engine Codes\u003c\/h2\u003e \u003ctable\u003e \u003cthead\u003e \u003ctr\u003e \u003cth\u003e139QMB Engine Codes\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e139QMA\u003c\/td\u003e \u003ctd\u003e139QMB\u003c\/td\u003e \u003ctd\u003e1P39QMB\u003c\/td\u003e \u003ctd\u003e1P39QMA-2\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eYN139QMB\u003c\/td\u003e \u003ctd\u003eJJ1P39QMB\u003c\/td\u003e \u003ctd\u003e139FMA-2\u003c\/td\u003e \u003ctd\u003eBD1P39QMB\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBN139QMB\u003c\/td\u003e \u003ctd\u003e147QMD\u003c\/td\u003e \u003ctd\u003eOther QMA models\u003c\/td\u003e \u003ctd\u003eOther QMB models\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch2\u003eCompatibility\u003c\/h2\u003e \u003ctable\u003e \u003cthead\u003e \u003ctr\u003e \u003cth\u003eMake\u003c\/th\u003e \u003cth\u003eModel \/ Engine\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eGenuine\u003c\/td\u003e \u003ctd\u003eBuddy 50, Roughhouse 50\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eHonda\u003c\/td\u003e \u003ctd\u003eJog 2T (vertical Minarelli)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eHonda\u003c\/td\u003e \u003ctd\u003eDio 2T (vertical Minarelli)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eVarious\u003c\/td\u003e \u003ctd\u003eAll 139QMB\/QMA 50cc 4T scooters\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"ChinesePartsPro","offers":[{"title":"Default Title","offer_id":53556331217208,"sku":"137-6","price":61.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0011\/8898\/6997\/files\/450809_1220x1220_crop_center__36632.1785961687.jpg?v=1792867127","url":"https:\/\/www.chinesepartspro.com\/products\/gy6s-137-6-naraku-107mm-sport-clutch-fits-2-stroke-and-4-stroke-139qmb-50cc","provider":"ChinesePartsPro","version":"1.0","type":"link"}
