⓸ HiT clutch

patented in USA, Euope

  • Amazing thrust force for solid engagement
  • Excellent over-taking & hillclimbing capability
  • Stop losing power at take-off & re-accerleration
  • No more blued bell
  • Longer durability of clutch assembly

The innovative HiT clutch, from Dr.Pulley ®  , uses motor torque – not just centrifugal force alone – a combination that puts this product in the upper end of power performance clutch systems.

Made of two interlocked movable parts, it’s originality is due to using a cleverly devised sliding/wedge system to create additional pressure that combines both torque and centrifugal energy

As opposed to the average clutch system which relies on centrifugal force alone. The stronger the motor (higher resistance for your motor to work with), means more pressure for the sliding/push-pin to exert on the surface of the clutch shoes, which means saving performance energy that would otherwise be lost.

Other clutches start to slip when they reach certain rpm’s or speeds. Not with the HiT clutch! Daily drivers get a new edge when going uphill or overtaking. Sport pilots appreciate increased power performance in higher rpm’s.

The HiT clutch, including two spring system

The first regulates acceleration rpm status, activating the clutch, which everyone knows. With HiT, the second spring system regulates aggressive power through the push-pin.
