250-500cc 09 WR 250 SM Wheels

Just wondering if a set of TE510 SM wheels would on my WR 250 from the same year? Any help appreciated.

Ok I've looked into it a bit and obviously chain is on the other side, but could rim (tyre) just be flipped, or is there an obvious reason why not? If I need to measure my hub, spacing to sprocket that's easy, was hoping someone knew off the top of their head but. Thanks again.

Happy to use the sprocket/brake rotor of my factory excels if need be, the WR rarely sees dirt.

The te hub is to wide by 6mm, i know as my 04 wr250 is at the bike engineers getting the wr hub relaced tothe sm rim.

Thanks, much appreciated.

Yup, you need the 151mm rear hub for the WR, front is the same.
As for gearing, you want the tallest you can get, the gearbox ratios are really short on this bike and gearing tall will help it run a lot smoother on the black stuff.
Here's a pic of my 300 with 15-39 gearing and I still wasn't using first gear at all;
