It helps keep CVT behavior steady over long periods of riding. It is also one of the \u003ca href=\"\/collections\/yamaha-zuma-parts\"\u003eYamaha Zuma scooter parts\u003c\/a\u003e that can sharpen mid-range pickup and help with climbing hills. It also lets the scooter back-shift more quickly, which makes it easier to handle in city traffic.\u003c\/p\u003e\u003ch3\u003eConstruction and Durability\u003c\/h3\u003e\u003cp\u003eThe spring is formed from high-fatigue silicon-steel, which holds its tension well and helps prevent \"spring sack.\" A dark coating adds some protection against heat and rust, especially in the rear pulley area. It measures 116mm long with a 54.5mm inner diameter.\u003c\/p\u003e\u003ch3\u003ePerformance Benefits\u003c\/h3\u003e\u003cp\u003eWith a 1000 RPM rating, the spring delays upshifting slightly, so the engine stays in its power band for stronger acceleration uphill. Riders who often travel hilly routes will likely notice this most. For the Zuma 125, pairing it with 10g or 11g roller weights can help balance performance across different riding conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM Rating:\u003c\/strong\u003e 1000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Length:\u003c\/strong\u003e 116mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter:\u003c\/strong\u003e 54.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter:\u003c\/strong\u003e 5.0mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-fatigue silicon-steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e Taiwan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Yamaha Zuma 125 (BWS, 2009-2021 air-cooled), Vino 125, and Cygnus X 125 (select models)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha Zuma 125 (BWS, 2009-2021 air-cooled models only)\u003c\/li\u003e\n\u003cli\u003eYamaha Vino 125 (all years)\u003c\/li\u003e\n\u003cli\u003eYamaha Cygnus X 125 (select models requiring 116mm length)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Check your current contra spring against these figures: 116mm length, 54.5mm inner diameter, and 5.0mm wire diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShop more:\u003c\/strong\u003e \u003ca href=\"\/collections\/yamaha-zuma-parts\"\u003eYamaha Zuma Parts\u003c\/a\u003e · \u003ca href=\"\/collections\/yamaha-scooter-parts\"\u003eYamaha Scooter Parts\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-transmission\"\u003eScooter Transmission \u0026amp; Final Drive\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-parts\"\u003eScooter Parts\u003c\/a\u003e\u003c\/p\u003e","brand":"Trend Times Toy Stores","offers":[{"title":"Default Title","offer_id":51138650505273,"sku":"TT-26609","price":17.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/3358\/9049\/files\/1000-rpm-contra-spring-for-yamaha-zuma-125-vino-125-1.webp?v=1794376561","url":"https:\/\/www.trendtimes.com\/products\/yamaha-zuma-125-vino-125-1000-rpm-contra-spring","provider":"Trend Times Toy Stores","version":"1.0","type":"link"}
