Well I'm picking a US version up to do some spec racing here against the EX250's. But ours are down on HP to the Euro and JDM versions.

But my questions are these. What engines are the 40hp ones? Anyone know? I plan
On importing some heads and cams from the yahoo Japan site. From what I can gather their heads and cam profiles give them more HP.

Any ideas?

Australia received the same version vtr250 as Japan (40 hp spec).

Well I guess I am asking what versions would that be. MC15? MC20?

Wiki has the info you're after under 'specifications': http://en.wikipedia.org/wiki/Honda_VTR250

The spada (mc20) is the model you want, they were sold new in Oz also.
