I had a ? about sprockets for my 05 R6. I am pretty sure that the sprockets are the same for 03,04,05 but I went in to my local cycle shop and picked out a 15tooth (1 down from 16) for the front. This was listed for a 99-01 but I had the guy look it up and he said that the parts #'s were the same for r6's from 99-04.

Just wondering if this is true or if there is a difference between the 99-02 and the 03-05 chain and sprocket sets.


Also can you just drop one tooth in the front without having to change your chain?


Update: on sprocket specialists.com the sprockets for the r6 with a stock chain have the same # for 99-04.

Another question, this sprocket I have might be for a 530 chain conversion, will that matter at all either?

If the sprocket you got is a 530 then you would need to change the chain and rear sprocket. The stock is 532. You could change the front sprocket without changeing chain if it matches the rest ie. 532. If you where to do a conversion do 15/50 520. thats the favorite in this forum.

yeah, I though that the 530 wouldn't work with the stock setup. I'll just have to order a stock size 15 tooth sprocket for the front.

I'll just try one down in the front for now and see what happens. I'll probably end up going with a 520 15-50 sometime in the future.

you can change a sprocket without changing the chain but it wouldn't be a bad idea to change the chain too. the old chain and sprocket has "broken in" together and the sprocket is worn according to the chain on there now. if you change just the sprocket it should be fine, haven't heard any horror stories, but if you have the money change them at the same time so the new chain and sprocket can break in. it's kind of like machining rotors before you put new pads on. the 1 down 2 up 520 conversion will make your bike a rocket but the top end will suffer.

i did a 1 down 1 up and my top end hasnt suffered much. i can still hit 158 but now im almost redlined where i wasnt before.

going to a new 15 wont be a big deal seeing as how your bike is an 05. it hasnt had enough miles to make the chain worn to the sprocket.
