Valve Timing; Screw Type Silent Cam Chain Tensioner - Royal Enfield INTERCEPTOR 650 2018 Service Training Manual

SLIPPER CLUTCH ADVANTAGES
The following are the advantages of slipper clutch over
normal clutch.
Slipper clutch reduces sudden forces on the inside of
the transmission and hence, reduces wear and tear on
the transmission
Correctly installed slipper clutch improves
performance.
It can prevent disastrous rear wheel lock up in case of
engine seizure or transmission failure.
It also reduces work of suspension by absorbing
engine braking force hence less bumpy ride while
cornering.
The rider does not need to concentrate on clutch
operation which allows him concentrate on other
things such as body posture, braking etc while
cornering.
