I have a 91 xr250l I am parting.
I'll let go the 21" wheel and the entire front end (forks, triples, spacers, axle, brakes (rotor is warped and master and slave need rebuilds) for $175 +shipping.
That front wheel alone is $75 +shipping and will swap right into my NX (I have raised the fender and modded the fork brace).
Adding a 17" rear and a 21" front brings the ground clearance up and balances the bike nicely.
Some will fall, others will laugh. I will do both.
