450r swingarm

[440's necessary]

I have a brand new Janssen 400ex swingarm, does it fit my 450r?

[Kurt Glore]

Not without modificaton. If the swingarm is brand new, why dont you call them and see if you can trade it for a 450 swingarm.

[ESrider]

I agree with with Kurt, if it's still new call Joel or Cory at Janssen and see what they would be willing to do.

It fits fine as long as you use the bearing carrier from the 400ex or 250R.

Do a search this has been talked about a lot around here.
