Still an issue
I have a 2008 990 Super Duke and after using the bike over winter, I suffered the brake seize issue. The bike would seem to slow and if I pulled in the clutch, it would come to a very fast stop. I nearly came off twice.
In Feb / Mar I got in touch with KTM Head Office in the UK and spoke to Bernie. He told me the UK councils are using a finer type of salt on the roads this year and it is causing a lot of corrosion damage to the bikes and is affecting the brakes. He said the corrosion built up and stopped the brakes from releasing.
Bernie said it was not a warranty issue but in this instance, as I look after my bike (I had it in with a dealer to have all parts and fasteners corroded over the winter replaced), he would get the brakes replaced FOC - disc's, pads, cables etc.
Whilst I cannot fault the support I received from Bernie, I do question the validity of his claim this is not a warranty issue. My bike was not even one year old and as a lover of biking and as I need my bike for work every day, if the roads are mucky or if it has been raining, I wash my bike down when I get home. I also treat the brakes with brake cleaner. That is why I find it difficult to believe that a bike of such quality would suffer an issue like this.
I hope this helps anyone suffering this issue. Don't let it put you off the bike if you are considering one as it is a great machine and fun to ride. I took it to do Level 1 at the California Superbike School last month (highly recommended) and enjoyed passing the sports bikes on the track. I just hope KTM do the right thing.
