How a Slipper Clutch works:

~Without a slipper clutch

At speed- and on a sudden downshift and throttle closure, the motorcycles rear wheel abruptly slows, hopping or skidding as it meets back torque transmitted from the crankshaft. The rear wheel now wants to spin the engine, vice the engine spinning the rear wheel. This is caused by the engine revs suddenly increasing- due to a shorter gear being suddenly mismatched with the engine speed. This generates reverse torque (engine breaking)-putting energy from the crankshaft back into the clutch. With large displacement 4 stroke motors, more engine braking is generated- a 2-cyclinder Ducati 1198 as an example, can create a great deal of engine braking. 

~With a slipper clutch

The reverse torque energy from the crankshaft is absorbed by the inner hub of the slipper clutch it's connected to- Similar to a torque wrench, a slipper clutch will break at a specific level of force- that force resistance is broke by the hub lifting up and shifting on the balls and ramps of clutch drum-pushing the clutch pressure plate out. This disengages the clutch friction discs, ultimately freeing the rear wheel from the torque of the engine. 

On the racetrack it allows you a safer and more efficient way to enter a corner while downshifting on the brakes all the way to the apex. Not having to worry about locking up the rear wheel in the brake zone is a major reason why riders choose a slipper clutch for the race track.  

Benefits of the Slipper Clutch:

- Prevent engine overrev

- Reduced clutch lever pressure

- Better grip in the clutch pack on acceleration

- Assists the rear shock and chassis to remain stable on corner entry

- Prevents rear wheel lockup before and during corner entry, emergency braking/down shifting 

- Can downshift without using the clutch lever (your clutch will last longer if you don't do this)
- Enable the controlled sliding of your rear wheel (backing it in)
- Better clutch lever release from a stop light or starting grid- due to the diaphragm spring
- Preventing damage to your engine components and gearbox 

- Mechanically assists and simulates feathering clutch manually- like required when riding without a Slipper Clutch

- Can enable faster lap time on the race track- enabling quicker down shifts and less to worry about in the brake zone.
