hey guys. Just wondering about cush drives. Are they really necessary?
Went to the KTM dealership today and was told that I shouldn't be riding my KTM EXC on the road without a cush drive hub due to excess transmission wear.

Wondering if they are really needed?
I don't ride on the highways, just local roads where speed limits don't exceed 80km/h.
Bike is a KTM EXC 2004 model.

You were told correctly!
The cush drive hubs will help stop transmission breakage on hard surfaces. There are some bikes , by other manufactors that have incorporated a torque limiter into there engine/ clutch drives instead of using cush hubs. Either of these are really needed for hard surface riding.

There have been people that have gone up to 15,000 miles + on the same bike as mine, with regular road use and no cush drive though....so judging by that, I'm still a bit sceptical on weather it's 100% totally necessary.
it might help, but not so sure its 100% a must, especially considering of all the people who have done so many miles on the bikes without 1.

what if your clean with your clutch control and not harsh with the gear changes?
and surely the clutch springs help dampen some of the effect too?

There is no dampening in the drive line with out the cush drive hubs or some other element. On dirt the dirt itself is the cushion, but on hard surfaces there is none. That is why road bikes have some sort of cush drive set up.

Do as you like, but if you do damage the transmission you will be out a huge dollar amount and be stuck on the side of the road somewhere. That is why road bike have the cush drive hubs. Your clutch offers no such cush.

I am amazed at folks that have already made up their mind as to what they are going to do, but yet ask the question in a forum and then want to argue when the facts are stated in response. Remember that my response is from many years of direct knowledge, but what do I know?

just wasn't sure weather it was worth my investment or not.
