Dr. Pulley HiT Clutch 251701 with 55 degree pillow springs for the Aprilia Atlantic 500 4T LC, Atlantic 500 4T LC Spring, Scarabeo 500 4T LC, Piaggio MP3 500 and many more. The Dr. Pulley HiT Clutch has 2 sets of springs at work: the clutch spring inside controls the movement of the clutch pads towards the clutch bell through centrifugal power. The second set of torque springs (pillow springs), externally mounted, controls the pressure by using a push pin on the clutch linings against the clutch bell. This prevents most of the slipping phase of the clutch, thus creating less friction and allowing less heat to be created. Heat is lost power! Thus your scooter will accelerate much faster due to the power transfer occurring at a lower RPM. The clutch can be customized to all personal needs. For example, if you want to get more power at start, choose a stronger clutch spring to increase the starting RPM. If you want to shorten the slipping phase of the clutch, you should use a weaker torque (pillow) spring. For an extreme start, choose a strong clutch spring and a very weak (or no) pillow spring. Overall Outer Diameter: 157mm. Center Opening: 44mm (width) 40mm (height). 55 Degree Pillow Springs. Includes 3 sets of Pillow Springs and 4. sets of Clutch Springs for Fine Tuning.
