Malossi Torsion Control Zuma Minarelli Dellorto KOSO's 4V Piston Kit forTransmission shifting can be negatively influenced by twisted contra springs, so Malossi decided to eliminate this problem with the Malossi torsion control, a new coated plastic seat. This way the contra spring is not placed directly on the torque driver reducing the twisting effect to a minimum. Furthermore, there are fewer vibrations on the torque driver at high revolutions so you can enjoy more linear gear changing and smoother power delivery.
