Hi I'm new here but done plenty of on and off road touring by motorbike in the past and am considering getting myself a ttr250 for some green laning and some long distance off-road tours.
so is seems your the guys to ask about these bikes.
what would you guys class as high milage for these motors (With appropriate maintenance) ?
what sort of miles do common problems generally occur ?
what sort of milage do people generally start thinking of doing engine rebuilds ?
i know it's hard to answer with great accuracy but these bikes have been around for a long time now so the must be some common themes .
Some have got their bikes to 25,000 miles without having to redo the valve clearances.
Only common theme with the TTR is a worn sprag clutch after time, but their is warning of this in the clunk of engine shut down, and its a relatively easy fix.
Only do engine parts if it starts smoking or rattling etc etc.
Mine has 35,000KMS. No repairs done as yet, and goes as strong as when i bought it with 9,000kms . They are all road KMs but i do give it heaps through the gears often. Prob look at valve clearance soon.
