It's going to give you a lower ceiling (is that a floor?) I would guess. Ther e is a ridiculous amount of NSR wisdom floating about here amongst Japanese racers; I am yet to meet anyone that has been in the game more than 6-7 years that hasn't raced NSRs. Of course that doesn't mean it's correct but they all tell me to do that.
Of course they're all riding CBR600RRs now, or the '05 GSXR1000 or some even the Kawasaki '05 ZX6R but no doubt 10-15 years ago the NSR was THE bike to race. It's almost a joke ... every time I go to the track they praise me to the heavens. When I ask them what I need to do to improve .. they say "get a 600". I don't know if it is specific to my riding style or just the current trend, but I literally can't even think about racing without everybody getting on my case to move on to a good modern 600.
I've been racing a CBR600RR via a team and I have to say it handles almost as well and has MORE lean angle than the NSR and is waaay easier to ride fast. My times are consistently 5% faster with less practise on the bike.
