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.

will i still be able to use the stock chain?? do u think it will pull up in second with clutching it. would u go 1 or 2??

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

If you are going to change the chain, mine as well do the 520 conversion. It would not be that much more. And you will good gains with this mod.

Parts 411 has this mod for $145 + shipping.

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?

Changing your gearing "dropping teeth" will affect your speedo.

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.
