the biggest difference that you would notice is at the pump...
when you change your gearing, you not only take out the top speed, but also your fuel efficiency.
-1/+2 = 15/45 = stock/+5 = 16/48
this gearing would make your front end pop up like a teenager in a strip club.
seriously, if youre skilled enough, your first and second gear is as fast as any liter bike...thing is, if youre not careful, your front end will stand up....and when you guys (your RR and the liter bike) click into third, the literbike would just make you eat his dust.
well, i guess thats the response youre trying to look for.
cbr/ls1's setup is good because it doesnt hurt the fuel efficiency as much
