BGM PRO Super Torque rear pulley/ torque driver for Piaggio/ Vespa 200-300cc LEADER & QUASAR engines.

The Supertorque converter has been optimised to keep the engine at its highest torque, with maximum power available at the rear wheel. Two groove angles allow you to adjust it to suit your needs. The pulley halves V-shape angle has been matched to the belt angle, the belt fully contacts the pulleys with minimum wear.

The milled groves have two angles, the steeper the angle the faster the pulley halves close. Standard engines should use the flatter angle for a more tamed ride. Tuned engines can take advantage of the steeper angle for increased acceleration.

Please grease the rear pulley (grooves & guide pins).
