Are all wheel bearing the same in a rear wheel from a KTM (125-525cc) I've bought a wheel off flee bay and the bearing need doing but I'm unsure of the age and cc the wheel came from. Regards

i'd measure it tbh.... then ask a dealer.

one thing i will say is you need to buy the kit, it may cost more then odd bearings, but it will last alot longer as the spacers wear.

mine lasted a good 6k miles before getting any play, then replaced with the kit and still going for 3k on and off road use

If they are 6005rs then they are the same.
