Dry Clutch

Dry Clutch:

The dry clutch is almost identical to the wet clutch the only difference s there are seals on the shafts that keep oil out. In the dry clutch set up the entire clutch is outside the case of the bike.


There is no oil circulated in to the clutch, which result into clutch knocking on itself. Ducati’s are almost the only bike with this type of clutch.
Advantages:
  • It is very easy to replace as it is outside the case of bike.
  • Oil does not need to circulate for clutch, which ultimately eliminate reduction in loss of Horse power due to oil circulation in clutch. It is the biggest reason why it is use in Moto GP racing.
  • You can use friction modified oils in engine
  • It is easier to use.
Disadvantages:
  • Sometimes it has tendency to grab during engagement which makes take off difficult.
  • The clutch overheats due to grabbing effect and wears out very fast.
  • The same thing makes clutch operation less progressive.
  • It has very shorter life.
  • Once hot it is very difficult to calm if there is no open clutch cover is there.
  • It is very noisy sometimes makes you feel like hammering.
