250r rotors on 400ex hubs?

[ssgtqrf]

I just bought a Roll Design A-arm set up. I know I need 400ex spindles and hubs but what about rotors? I have a set of Baldwin adapter plates to use my stock calipers but will I need 400ex rotors?

I tried searching but couldn't find an answer.

Thanks in advance

I think the 88-89 250r rotors will fit on 400EX hubs. Both have the 3 bolt mount rotors. The 86-87 250R has the four bolt rotors, so those will not work on the EX spindles. I believe the whole hub from the 88-89 R will fit on the EX spindle.

Sorry to do a bit of hijacking of the thread but I need a rear disc will a 400ex rear disc work on my 250R? It's an 86 if that matters.

Thanks for the reply,

I have an 87 so I will just pick up a set of 400ex rotors. Atleast they are not expensive.

Also I am learning a ton by building this quad. I just can't wait to get it all finished. I bought so much now I just need the time to get all of it put on.
