I have both bikes and havent drag raced them yet!!

Both run 14/46 gearing.

On a terminal velocity which would win?

I think the CRF would get the jump and possibly midrange because of that smashing mid hit but would the XR keep up at the end?

(the XR is highly modded - HRC engine, massive oil cooler and big pipe with a flowed head. CRF is stock. Both bikes as new) I think my 628 has about 55HP


Having ridden both lately I think the CRF might have the CR but surely not?

Interested in anyone who has done this.

It's a bit off topic, but what do you mean HRC motor (for the XR)?
Could you please list the mods?
