What does lots of road riding actually do? WR250f

The WR is very durable. Change the oil often as it will shear faster with no cush hub and street use, and use good synthetic stuff.

The one issue i had while on motard setup for 2 years was the flywheel(Rotor) shakes the two halves apart until the rivets are loose and ignition timing goes to crap. This happened 3 times twice on brand new flywheels once with replaced oversize rivets. I returned it to dirt trim after that.

Ive heard that running on knobbys is more forgiving than the slicks i was running as the engine "putts" are somewhat absorbed by the tread like a cush drive.

Glad to get confirmation on the loose flywheel from street wheelies. I'm sure that's what happened to my bike, even with knobs (but knobs probably help). I agree that if you don't hammer gears at peak power you should be fine.
