I have a 08 CBR600RR I just bought a 49 tooth rear Vortex spocket and D.I.D chain, do I have to change the front spocket or will this setup work any help is appreciated

 

Normally you want to change both sprockets and chain at the same time,, but being the bike is new and the front sprocekt has limited miles on it,, you should be fine. did you get a longer chain. +7 in the rear is alot, plan on stunting?

 

Yeah I bought a D.I.D 120 link chain, and I can ride wheelies right now, but the 600rr just takes to much out of u pulling it up, so I figure plus 7 teeth should do the job

 

does your speedometer change when you change your sprocket size.

 

yes.

 

I havea +4 rear and a -1 front with a gold rk chain. I also have a spare stock front for an easy switch.

 

whats a spocket?
