[hondaracer3x]

I found one cheap and I am wondering if it will work

yes but i beleive ou have to use 250r hubs and I think the brake carrier and sprocket carrier??

im not sur eon the brake and sprocket but I am posisitive on the hubs...

Yes it will. I am in the process of putting a lonestar 250r axle in my 400ex right now. Parts required are 250r hubs, castle nuts, and a locknut(the 400ex locknut doesn't quite make it to the snap ring groove on the aftermarket 250r axle). Best to just get an aftermarket lock nut. ;)
