    A loal shop has a 250 4stroke rear hub, around 2009 model. question is will the Hub fit the rear of my WR300? my bike isnt close at hand to check. The shop said u can just flip it over as the 4t has the final drive on the left side as opposed to the smokers being on the right side.

    hoping some can advise if it will fit ;)

    cheers

    The tabs where the sprocket mounts are thicker on a 4 stroke hub and the sprocket alignment will be off about one sprocket thickness worth. I have a friend who turned down a sprocket and used it as a spacer (I recommended not doing that but he has not had an issue) to use a 2 stroke wheel on his 4 stroke. Going the other way you would have to machine the hub down so the sprocket aligns.

    thanks guys, i will check how thick the sprocket tabs are and see if this is viable. being a smoker i guess the torque is less so maybe the thumpers are thicker by default. i will check an let u know the outcome.

    I just check the hubs side by side and it appears that the 4t hub has extended tabs (thicker by approx 8mm) than the 2t.
    Going by this your correct Motosportz :) I will send it to the machine shop and have the sproket tabs taken back. This will actually
    make it identical to the 2t tab thickness. That would mean it wont be any weaker than a stock 2t hub.
