EVR F4/Brutale/SV 1000 Slipper Clutch

A new slipper clutch that revolutionizes the concept of racing clutch. The function is activated by a cam unit, which, under the push of the rear wheel, raises the cover freeing the disk pack from the load springs. All other systems on the market now, move and raise the central hub, supported on inclined planes, generating a strong friction between the teeth of the discs and hub and making the slippage rough and unpredictable, especially when the hub is already worn. Thanks to the system patented EVR, the spider spring is no longer required and the life of the clutch discs is considerably increased, up to three times more.
