The contrast spring is usually harder if the belt tends to slip, if the variator does not \u003cstrong\u003eoperate at the optimal RPM level\u003c\/strong\u003e, or if the engine, despite light weights, continues to run below the optimal RPM.\u003cbr\u003e What negatively affects engine performance is a twisted contrast spring. With the \u003cstrong\u003eEvo-Slider plate\u003c\/strong\u003e, the manufacturer Polini provides a solution to this problem.\u003c\/p\u003e\n\u003cp\u003eThis is a small plate that is mounted between the contrast spring and the clutch, which \u003cstrong\u003ereduces torsion\u003c\/strong\u003e to a minimum. In addition, the Polini Evo-Slider absorbs \u003cstrong\u003epulley vibrations\u003c\/strong\u003e at high RPM. \u003cbr\u003eThe result is a \u003cstrong\u003esmoother engine\u003c\/strong\u003e and \u003cstrong\u003ebetter power transmission\u003c\/strong\u003e to the rear wheel. \u003cbr\u003eThe \u003cstrong\u003ethicker\u003c\/strong\u003e the diameter, the \u003cstrong\u003eharder the contrast spring\u003c\/strong\u003e is.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe kit includes\u003c\/strong\u003e a harder spring and an Evo-Slider spacer. \u003cbr\u003eThe \u003cstrong\u003ePolini Evo-Slider\u003c\/strong\u003e allows the spring to rotate, which significantly improves the Maxiscooter's behavior when \u003cstrong\u003estarting from a standstill and throttle response\u003c\/strong\u003e\u003c\/p\u003e","brand":"Polini Motori s.p.a.","offers":[{"title":"Default Title","offer_id":54307749298561,"sku":"243.099","price":38.13,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/243.099.jpg?v=1750286803","url":"https:\/\/motoscoot.net\/en\/products\/contrast-spring-polini-evo-slider-yamaha-t-max-500-530","provider":"Motoscoot","version":"1.0","type":"link"}
