Nowadays many of the bikes come with a slipper clutch(also known as a back-torque limiter), The main construction difference between a normal clutch & slipper clutch is in clutch base & clutch hub.
To better understand the benefit of slipper clutch consider you are riding a bike with the normal clutch in top gear & you are riding it at high speed(80+), Accidently if any object comes in front of your motorcycles like other cars or animals, Brakes are not enough al the time, you have to downshift gear to reduce bike speed efficiently. But in a bike with a normal clutch, there is the possibility of damage in the gearbox or locking your rear wheel & there will chance of an accident.
When you do de-acceleration at high speed or suddenly downshifting at high speeds two things happens, the engine braking force gets very high & the normal clutch gets stuck.
What Is Engine Braking?
To understand the whole concept of a slipper clutch you should also know what is engine braking. To stop a running bike on road there are two methods, 1. Brakes (What everyone knows) 2. Engine braking (What professionals use).
You may notice, when you take the accelerator your bike goes first, But when reverse the accelerator your bike goes slower, this is because of the Engine Braking forces. Your bike also gets slower by downshifting & without any brakes. All the racer like MotoGP racers & professionals use this method to slow their bikes & you may also do this but in a proper way & try ignoring it if you own a bike with the normal clutch.
The working formula of Clutch
In a normal clutch system, only two things happen, you can only engage & disengage the clutch, When you completely leave the clutch on that time the power produced by the engine transfers to the gearbox & when you press the clutch the power gets disconnected. In a normal clutch, only these activities happen.
To fix all the disadvantages slipper clutch was introduced. In this clutch system everything happens, Clutch engagement, Dis-engagement & also when needed the clutch slips also.
Now I want to tell you that, when a bike with slipper clutch runs in normal conditions like, in low speeds, what happens that time, The clutch base ramp & the clutch hub engagement docks they engage themselves & powers easily transfer in the rear wheel. But when you suddenly de accelerate your bike then the clutch comes into action, The ramp & the clutch hubs gets slips & you get the downshifting benefit. It gets slipping till the rear wheel speed & the engine speed doesn’t match.
And in this way the slipper clutch gives you better de-acceleration, better downshifting, and also in better hard braking, All these benefits you get in theis clutch.

Disadvantages of Slipper Clutch
The disadvantages of this clutch system are the construction of slipper clutch is a little bit complex so it’s a little bit harder to maintain it, The parts & labor charges are higher, It’s very much expensive compared to Normal clutch.

FAQ’s About Slipper Clutch
Do I need a slipper clutch?
Basically, race-track motorcycles use it because it helps to realize faster lap times. The rider can easily coordinate the speed and braking without losing traction. But considering the security of the rider at high speeds, many manufacturers today have widely adopted the slipper clutch.
How long do slipper clutches last?
20,000 to 50,000
Proper usage and maintenance, can last anywhere from 20,000 to 50,000+. Depends on what bike we are talking about. Clutchless shifting wears it down, especially from high to low.
Which is the better wet or dry clutch?
Wet clutches generally have a pleasant wide friction zone that creates them pretty easy to use. They also tend to last an extended time, and they are quieter than dry clutches. On the flip side, wet clutches do make your engine oil dirty faster since all the dust that’s created because the clutch wears stays inside the engine.
