Naraku clutch center springs NK900.47 Sport Minarelli - 2 pieces

In the variator drivetrain, the counter-pressure spring ensures that the V-belt does not slip and also influences the speed at which the variator changes the transmission ratio, i.e. “upshifts”.

If the performance of the vehicle has been increased, a stronger pressure spring must therefore always be installed to prevent the belt from slipping due to the higher tractive force. The shifting characteristics are changed in a similar way to the installation of lighter variator weights and can be further tuned with these.

We offer a set of 2 Naraku Sport V.2 counter-pressure springs for tuned 50cc scooters and quads.

TECHNICAL DATA:
