2513210 OEM Malossi Spring Torsion Controller for Aprilia Atlantic200 Mojito 150 Official Malossi Accessory. OEM part nr: 2513210. Imported from Italy. Please note this part replaces the following parts: M2513210 Features:• Malossi Spring Torsion Controller• Spring Plate Malossi torsion controller• This little wonder will decrease vibration and stabilize transmission operation at any RPM and temperature. • During the automatic CVT power curve, the bushing of the torque driver makes a small rotation, giving torsion to the contrasting spring. • Sometimes the spring will bind or remain stuck in its position causing some un-wanted forces (jerking and/or bucking). • Also, the centrifugal forces caused at high rpm causes the spring to buckle and veer, which can create a big vibration, very annoying for the driver as well as harmful to the engine and, above all, making for an unsteady power curve and loss of power. • The installation of this Malossi Torsion Controller can help eliminate these problems by smoothing out the binding and simultaneously pre-loading the stock spring. • This is simply the best little performance item you can buy for a smoother transmission and improved power on a stock or fully tuned scooter. • Clutch spring NOT included, price is for one slider, which is all that is required.
