Yeah, if you pay attention to 'middleweights', they've been going up in displacement in order to provide similar power levels under Euro4.
Ducati went up from 696 to 795, then 821 with the Monster. The Baby Panigale went from 899 to 959.
Kawi's naked bike went with an 800 triple then upped to a 900 triple.
The Triumph just moved from 675 to 765 (which won't confuse anyone with typos).
It may be the supersport is tapering off as a road bike, and people on track are going to be looking at literbikes for track purposes. We may continue to get more and more offerings in middleweight in street tripm(naked, upright, 'standard').
Never ride faster than you can stop
