It seems like I'm getting about 10,000 kms for each slider. I have also been thru about as many chains. I ride it and I'd it when broke, spray the chain with oil once and awhile and change the motor oil every 3000kms it's a bike not a piece of art work, it's made to e ridden and ridden hard it gets. Currently sitting at approx 31,000 kms and I've only had it for just over a year. Bought used with 6,000kms last nov.
