Difference between 400ex and XR400 motor?

Recommended Posts

Is there a difference between the 400ex and the XR400 motor? Are the cams, valve springs, rev limiter etc all the same. I know someone looking to do some up grades to his 400ex. He was told to use the XR cam in his 400ex.

The cams are interchangeable. The XR400 cams have more agressive timing than the 400ex ones but are not too radical.
