ok i just installed my front sprocket saturday night on my 07 cbr 600rr.i did the -1 and WOW i can't believe the difference just from that!!!i don't even know if i'm going to switch the back to a +2!!the front tire wants to come up easy!i prob will do the switch after i get use to this new one. its gonna take some time though.i didn't think i would get THAT much of a change from such a cheap upgrade.it a GREAT bang for your bucks!!!

 

good
might as well do the +2 as well and get it all over with at once. the front wheel will stay down if you position your body correctly for hard starts.
