everyone opinions may vary on this, The book says 12 hours, I'll tell you, your motor has already been run at wide open throttle, KTM motor dyno's every engine to insure it's up to snuff, then they install it into the quad and chassis dyno the quad, if I remember right 15 minute engine dyno and 20 chassis dyno, I broke mine in on the dyno at WOT, mine has 49 hours now and still is making the same power as it did new...

I find this a good article about that matter

The key to successful break-in is to ride the quad easy but not so mellow that the rings cant seat within the cylinder. The best way to do this is to combine a high load with low rpm. In other words lug the engine a bit by riding smoothly in a higher gear then necessary as opposed to popping it into one gear and revving it out.


I would say, change the oil frequently in the first 15 hours.
KTM says, the first 3h with 50% throttle and the next 12h with 75% throttle so it's a total of 15h break in. Yamaha says more than 10h also, etc
Of course no one follows that :p

And did you have any probs with the engine after that? (i know it doesn't prove anything, it's just 1 atv)
