Author Topic: Will a 400EX axle fit 250R??? (Read 12157 times)

I have been running one on my 450R for years, as well. No issues, chrome is like new! For the trails small jumps, hard to beat.

That is correct Fred, where your showing, because if you dont put that 3/16" spacer on the axle, the chain will be just a bit out of aline with the front sprocket. If that spacer not used, it might run like that ok, but would probably wear the sprockets more on one side & a lot more attention would need be paid to keep the chain tight.
On my daughters R, hers has a chain guide on the swingarm & the chain was out of aline enough it was rubbing one side of the plastic guide.

What are those 400EX Tusk axles going for now ?.
Ohhhh, you'll also find even with using the extended type 400EX hubs, the 400EX extended axle is 1" shorter than the Lonestar +4. That 1/2" narrower on each side didnt bother us though, just tightened the ol girl up in the corners a bit more.

Thanks Neil. They still cost $200.

I would like to share my setup and possibly point out possible flaws in what was mentioned previously. I am running a LSR 400ex axle in my 250R. To use the 250R anti fade I did not machine the disc side of the hub, if you do so the disc moves towards the swing arm...which will ruin disc to caliper alignment...I machined the back of the anti fade nut itself and the large threads that go inside the nut...this gives you clearance for the circlip and doesn't affect brake alignment. This setup does not require a washer on the sprocket side either.
