I'm looking at buying an '05 1000rr i took it for a test ride and it has a slight bar wobble at slow speeds (stops at about 80km/h). Any ideas on what the cause could be?

 

My first guess would be bad wheel bearings.
Another possibility is a front caliper is hanging.
Less likely, but possible (from your comments) would be bent rim.

Unless it's a really, really good deal, (i.e. 10 cents on the dollar) I would walk away.
The probable cause for an issue like that is a botched, cosmetic repair after a crash.
I'd be wondering what else is wrong, that you're just missing right now.

i'd have to agree with madhattr ^^^ doesnt sound like a good deal... could be something simple but then again it can very well be alot of things...

 

Thanks for the advice, it was very helpful.
