No I haven't ridden the 300cc, as it takes some 1200$ to do so, so I'm trying to get the facts right first.

Please understand that I'm asking questions, not because I doubt your experience ( that a guy goes back to 250, sounds pretty convincing) but rather to understand.
I believe theory and practice go hand in hand and I couldn't get the curves to confirm peoples experience.

Maybe we all should cheer Matt along, so he'll come up with the ultimate 80+ kit, with a such a peak that only Rossi can ride it.

And yes, I too love the kick from 9000rpm and up and don't care about street rideability. If I wanted a commuter, I can fall asleep on/in, I'd buy a diesel 4 wheel, automatic..
