Hi guys,

Has anyone tried dropping one or two teeth on the drive gear?? how much more bottom end did u get? and much top end did u lose? I don't really care for top end.

I wanna drop one or two teeth do get some more bottom end for wheelies in second gear without having to clutch it.

any info would be great.

I dropped one tooth on my 2000 R6, and I love it. The bottom end it of the powerband is awesome. And as far as top end goes, the R6 just seems to have plenty there to spare. I would definetly go with at least one tooth down. Actually I would do 2 teeth after speaking from experience.

I know from going down 1 tooth you can use the stock chain, you might have to do some more research for 2 teeth though because I dont know about that one. I would have loved to go 2 teeth down though.

You should be able to use the stock chain dropping 1 tooth but while it is off, you might as well replace it.

I guess changing the sprockets out and keeping your old chain is like changing your oil and not the filter

I dropped a tooth playing football when I was a young buck. Didn't really affect my top end one way or the other.

why would i need to replace the chain? the bike only has 952KMs on it, its brand new. Or did u mean if it was an older bike???

also where does the 2003 R6 read the speed from? front tire, tranny??? will it mess up my speedo, dropping 1 or 2 teeth?

The speedo sensor is on the front sproket. So changing it will affect your speedo. But you can get a yellow box to correct it. I will look up the link in a little bit.

As for replacing the whole chain to a 520 drops like 3-4 pounds of rotating mass the motor has to spin. So the less weight, the more power that gets to the ground. A new front sproket should be about $25. The rear sproket is around $50 by itself.

Your chain isn't already off, it just isn't on the sprockets. You have to take the link out to take it off- not something that is really easy to do. If your chain is still pretty new, then there is no reason to waste money on another chain & rear sprocket. If it is an old POS chain, then yeah, buy a package that is a tooth lower, and change it all.
