Sprocket advice
I have a 2003 gsxr 600 and have had my current sprocket setup for 2 years and I am pretty good at wheelies. It's time for new sprockets due to wear so I'm thinkin of changing it up and need some advice. My current setup is -2 and +6. I want to do slow stuff and I'm starting to learn highchairs. I want a be able to bring it up with no effort but smooth. I am thinking of going either -2 and +10/+12 or going back to stock in the front and +18 in the rear. I am asking here cause I will get the best advice.
Thanks,
Ryan

Re: Sprocket advice
your gearing now would work fine, my bike was no handed all the way acrossed the lot with -1/+7 on my 600RR, unfortunately it wasn't by me, and I still can't do it, damn you Aaron

Re: Sprocket advice
It's both what I ride and stunt on so it has to be streetable as far as rpms. I know that my current setup would work I just wanted some change. The shop I work at service manager told me it wouldn't be so hard on my bike if I went -1 instead of -2 on the front sprocket. I just want smoothness like we all do. Thanks for all the replies.

Re: Sprocket advice
Stock or -1 in the front will wear all the components less. you can acheive exactly the same ratio with a stock front as you can with a -2 just make the back bigger. Just take the rear sprocket teeth divided by the front teeth.
For instance on my stunt bike i have 15, 56 or stock, +16. so my ratio is
56/15=3.73
I can get almost the same ratio with a -1, +12
52/14=3.71
The ratio is the key. But a larger front sprocket will save wear on parts. the main reason to go down in the front is to save money by not needing to get a new chain and rear sprocket and still increase the ratio.
For instance on my gsxr1000 i went -1 for ~$25 but if i would have changed the rear to +3 i would have acheived the same result but the sprocket would have been arounbd $50 and I probably would have needed a new chain for about $100.
So if you need all three components you might as well get a stock front sprocket and a slightly larger rear.

Re: Sprocket advice
So there is no torque value to having a smaller front sprocket? Will it be a smoother pull with stock in front and huge in the rear? Does anyone know what the biggest is you can put on a gixxer with a 750 swingarm, it looks like it would hit after getting so big. There is some really good advice here, keep it coming.

Re: Sprocket advice
Going down teeth on the front sprocket will give you the same results as going up on the rear (all that matters is the ratio, as ripley said) however, smaller front sprockets put more stress on everything.

Re: Sprocket advice
Ok, going off of riply's formula I am going to go with stock in the front and 15 up in the rear so that will be 16/60. I think I am right with this cause I got -2 and +6 now and going with that setup would be like going -2 and +10, right? I hope this gets the job done cause my dude at the cycle shop told me $87.99 retail and $68.39 with a discount, from sprocket specailists. I will wait on confirmation from you guys before ordering this.

Re: Sprocket advice
going down a couple in the front doesn't stress anything too bad!
it lets you run a smaller rear too, which looks better and has less of a chance to catch you fingers in a crash!
I would run -2 +12 (actaully that is what i ran in 2004) over stock +18 anyday!!!
