"Rekluse z-Start Pro Clutches are good things, and they are built really well, not much heavier than a stock one. They are just an awesome thing to have; they suit my riding style." - Mitchell Cooke - Canadian MX Pro
Featured Rekluse rider for August is Pierre Koether of Boise, ID! Check him out training for the 2008 EnduroCross season, on his way to 7th place at Round One!
Rekluse ProStart Clutch with Torq Drive
To get a smooth initial take-off, a traditional centrifugal clutch will slip between 1500 and 2500 RPM under hard acceleration. This slip at low RPM smooths out the torque pulses you normally feel when rolling on the throttle from low RPM.
The ProStart with Torq Drive gives a smooth initial take-off and then hits hard, delivering all of the engine’s torque to the rear wheel. With Torq Drive, the rider can feel the engine’s torque acceleration as the ProStart matches the torque output of the Harley-Davidson engine.
Torq Drive is a patent-pending technology from Rekluse Motor Sports. The Rekluse pressure plate is specially designed to generate this special torque matching capability. As RPMs are increased above idle, centrifugal force pushes the balls up the ramps and forces the pressure plate down, engaging the clutch. From approximately 1100 to 1350 RPM the clutch engages smoothly through the steep part of the ball ramp. Above 1350 RPM, the Torq Drive feature engages matching the torque production of the motor and providing ultimate performance.
The following chart shows the linear engagement of a traditional auto clutch versus the torque matching capability of Torq Drive.
