Hard to answer since it depends on what the bike is used for. if you want to keep maximum MPG, then stick with the stock gearing. If you want max acceleration without being a real wheel whore, then 15/50. If you just want a little bit of power and your stock chain is still fine, then look around for a 15T front in a 532 pitch. It will only cost you under $30.
Got it, so more like 15/45 is better for me? Thanks for clearing that up. anyone know for sure what the stock specs are on the sprockets on the 08 R6? I did not find anything in the manual or the shop manual.
IF you need a Good Track Accelaration kit kit for your R6 i'll recomend stay close to stock as much as possible.. cuz your bike is gear and tuned to stock.. and every mod you do there is always and advantage and disadvantage... if you need a goo accelaration on a the exit of a turn.. i would recomember.. to keep the stock Rear sprocket tooth count to the same and just go -1 on the front ... this will accelarate a little bit faster you'll probably lose between 5 to 10 mph on top speed... but still if your looking for a good accelaration on exit .. this is much more easier and good for your bike when it come to rev... i have a vortex 520 accelaration kit -1 on the front with RK chain and its rated for a 1000cc bike... and i have it for my R6 ... its lither than stock..if you have more budget on your hand then the D.I.D chain would be the one you want good luck
I've done the 16/50(+2 rear only) on my 03 and have been very pleased w/the results. I tried the 15/50 at the track, and loved the outright acceleration, but was find that type of gear too short for the tracks I frequent.
