Ho, crap ...
The Kawi engine also exist in 250 form, maybe I need to start on that one ...

I dunno...the 500 with modified cams could do better on the highway thanks to lower revs and better balance (less friction), but yea 500 is a bit big.
Personally I like 4 cylinder bikes for the sound and I'm okay with losing a little fuel efficiency for that absolutely beautiful scream, and I think the reasonable 4 cylinders start at 400cc (while the CBR250 was really cool, it's a bit stupid to constantly be using 10000rpm on the street from a practical point of view). 600cc is just crazy, they almost match the power of my car, which is fast enough as is.
If I ever go abroad to a country where it's harder to get killed riding a motorbike, I might have to get myself a CBR400RR and retrofit it with fuel injection.
