Mine is coming up to 40 000 miles now (30 to go) and the only things I've needed to replace in the rear wheel bearings and I've just done the head race bearings. Front pads only just changed! On third set of rears. Changed chain and sprockets at 18k but fitted a scotoiler and new one is still going strong.
I have a owners review on my website that you might find useful.
I think most people buy them to get into the adventure scene but then find them to underpowered having come from a multi cylinder road bike. Or it could be they are a little tall?
