twist control Naraku racing 107mm w/o torque spring for Minarelli NK900.52 fitting for Adly/Herchee PT50 50 ,

Twist Control: an absolute drive innovation from Naraku. Twist Control absorbs the torsion from the converter and even out the loss of power from the lack of friction. The result is smooth converter function that makes a significant difference on untuned engines. The vehicle accelerates better and the height of the spring preload equates to a 15% stronger counter pressure spring. Heat-resistant torque driver grease should be used for the system. For use in untuned and racing engines. Counter pressure spring for illustration purposes only and is not included in the delivery! Attention: Twist Control is suitable for original Minarelli and tuning torque drivers. Where an aftermarket item is installed, use the Twist Control for 105mm clutches. Item No: NK900.45
