with the right valves / piston / compression ratio theres no
reason you couldn't make the motor last a lot longer.
I looked at the WR250R but they are a 2008 onwards model
and hold there prise... the WR250f takes a rekluse clutch..
edit.... just found this for a WR250F..

full skirt 3 ring piston ... high compresion ,but a few base gaskets will sort that..
