Thread: Wr250f engine life

    Default Wr250f engine life

    I have thought about buying a new wr for trail riding fast single track, Im used to a 250 2 stroke, and I mostly ride low to midrange rpm, Im wondering how many hours engine life for the top end and bottomend and valvetrain, of these engines.

    Agreed. I flogged my 2014 yz250f in enduro racing. Treated her well and had 240 hours when I sold it. Valves never moved. Crank looked perfect and in spec when I sold it. Just sold my 17 with 100 hours it was perfect as well.

    How many top ends with 240 hours, sounds very impressive, I know of a xcf 350, 300 hours and it hasn't been touched, I ride with the guy that owns it and it never sees high rpm mostly 6000 rpm or lower. I am mostly wanting to try a Yamaha for the suspension and get away from wp forks.

    The reality is that everything depends on YOU. How you ride, maintenance and your expectations. A weekend racer will replace pistons and rings between 50-60 hrs a more serious race at around 30hrs and a play rider will go until it is totally wore out. Just remember any 250 is not going to last as long as a 350-450 of any make. The Yamaha is one of the most reliable 250 motors it`s main issue like all Japanese bikes is the clutch but is mostly for those who race.

    Yes I understand that, Im not hard on clutches and do not rev the motor no more than I haft to. Im 51 years old and try to conserve energy, I still ride as tough single track as I used to, actually tougher single track, but I use a recluse and tubliss to.

    I have a buddy with a 05 WR. He’s owned it 3 yrs and rides at least twice a month. He doesn’t have an hour meter but I put 200 hrs on my bike in 2 yrs and he rides almost as much as me. And he has no clue how many hours were on it when he bought. Bike mechanic told him this year valves looked great
    2017 250-xcw
    2008 250xc- sold
    1998 250exc - gone

    What wears on any bike are the piston and rings and it`s the same life span for most of the makes, that life span i outlined in an earlier post. Sure someone can tack on the hours but the longer the hours the more the performance is affected and subject to failure. Engine life is not valves staying in spec.

    I agree. I had a 2001 WR250F and road the piss out of it for 4 years. It had near 200 hours on it when I sold it. Never had a valve move, or any maintenance problem. Bike had the oil changed every 8-10 hours (Amsoil) a 2003 intake cam to remove manual decompression lever and ridden and raced in Dist 37 Desert and Big Six.


    IMO the WR250F is the BEST of the Japanese 250F bikes.
