I have an 08 superduke, and the front tyre is cupping. The independent shop says I have bad fork bushings or low fork oil height( without seeing the bike). I bought this bike new last year and only have 3500 miles on it. Is this possible? Does any one have any experience with this?

#4Never trust shops or previous owners to know what the're doing. Check everything yourself to have a known base line to start with.
Motorcycles are like airplanes. The pilot is responsible for checking it over before takeoff. Your life depends on it.
A mate of mine rode his bike over 2000klm. Front tyre chopped out after 700klm. Replaced it and kept going. New tyre was showing the same problems. Finally put it into a shop and found only one fork had oil in it.
He had the fork oil changed at a shop before he left home. The wankers put the oil volume for both forks into only one fork.

#5I bought this bike new from a KTM dealer, I assume that the factory filled the forks with oil.

#9Can also be down to bad rebound or pre load settings!

#11I'm going to make this very easy for you. Yes, I could write a bunch of paragraphs about your problem - beginning with the most common suggestions already put forward, followed by yet another droll (to some) discourse on the hows and whys.
If you bought this bike "new last year" as you state, and its a 2008, it is still under warranty. It is warranted for 2 years.
The promised "easy" part: Take it to the stealer (any KTM stealer), and have them deal with it. Exercise the warranty.
Back to the thread we're supposed to ignore, because frankly, this is tiresome.

#18I'm not as quick as Bert, but then again I'm human, not a AI supercomputer.
Hope you get this sorted. How do the forks feel on braking and when you release the lever?
How does the front feel over bumps?

#19Seems to feel fine, the front end is alittle harsh. But I like the solid feel.

#20post up a few pics. and we could help find the reason for whats happening to you tyres.
Post 21 by TLS_Russ,
#21It's very unlikely the cupping you are trying to desrcribe is due to worn suspension bushings (or low fork oil)....your bike is fooking brand new. That shop is trying to get you to drop off your bike so they can milk some cash from you.
It's likely down to pressure (over or under), mileage and age of the tyre. Is it the original tyre? If so, I think your problem is solved as that tyre would be greater than 6 years old. Put on a new set of Q2s and call it a day.
