Thanks to the redesign of the roller ramps and the angles of the fixed and movable Air Speed pulley halves, a greater travel of the \u003cstrong\u003edrive belt\u003c\/strong\u003e is achieved, providing more linear power delivery and immediate throttle response.\u003c\/p\u003e\n\u003cp\u003eThis transmission kit helps keep the engine within its optimal rpm range during the acceleration phase. By incorporating a \u003cstrong\u003ePolini contra spring\u003c\/strong\u003e with 10% more load, loss of traction during hard acceleration is reduced. The kit includes two sets of \u003cstrong\u003e20x17mm rollers\u003c\/strong\u003e weighing 17g and 22g, making it easier to adjust the transmission on the \u003cstrong\u003eVespa GTS 300\u003c\/strong\u003e according to riding style.\u003c\/p\u003e\n\u003cp\u003eThe manufacture of this component stands out for its hardened and ground chrome-nickel steel pin, which minimizes the coefficient of friction to prevent premature wear. The silicon-alloy movable pulley half, machined with diamond tools, promotes heat dissipation in the transmission.
