Gearing the GSXR

Well lets see here....My bikes gearing is pretty good stock. I mean it will do a stand up in 3rd no problem.....But i was thinking today should i drop one front tooth or raise 2-3 in the rear i know that 3 rear teeth equal 1 front tooth but i have also heard droping one in the front is harder on your chain....Lookin for alittle more acceleration because i know it has to be there...Sure with the gearing now it will do 176 (on the speedo) but who needs to go that fast....Also if i do this is there anyway to correct the speedometer? Cause i would like it to be accurate and i know that gearing throws this off.....Help me out guys.

Re: the speedo... double check where your speed sensor is located, on the SV's it's on the front wheel. So gearing changes don't affect the speedo reading. If it isn't a direct sensor to the wheel, then you might need to correct for a gearing change.

Best to see how many teeth are on your stock front sprocket first. If 16 or lower, change the rear sprocket. The lower the number, the tighter the bend, the quicker the chain wears.

But if I had a new Gixxer and wanted more power, I would look at ignition, fuel, and exhaust mods first.

Remember when you were a kid and you cliped a card on your frame so it made noise flippimg through the spokes and you thought it was a great upgrade to your bike because now it sounded like it went faster? just a little joke.

You can probly get away with going -1 in the front and +2 in the back w/o problems. Look into a speedo healer.

speedo healer is a must for changing factory gearing. The sensor is on the countershaft on the new Gixxers. I would go down one on the front first and use that as a gauge to see if you need more. -1 front and 2+ rear is a big change but still acceptable. Anything more than that and the rpms get way crazy trying to ride at highway speeds.

I rode my buddy's '03 ZX6R on the track at Miller and he has -1/+3. It was pretty ballsy. Felt good to me. Didn't really oen it up too much though. I was too busy concentraing on the turns. I'm actually thinking about going -1/+1 on the R6. but I think I'll wait until the current set wears out. by that time, i should have the full system in place with the PC and an added 10hp at least. That might do the trick. we'll see. But definately get a PC for your bike. I'd wear out your stock gearing before you decide to buy new sh*t.
