Looking to get a bit more low-end and sacrifice a bit of top speed. Thinking a sprocket swap might do the trick. I know the rear sprocket is needed, but what about the front one? And the chain...what to do there? Anything else necessary? Sorry for the noob questions.

The stock chain/sprockets are a 530 (its a rating based on strength/width of the chain). You're hard pressed to find an aftermarket kit for the 530. Most of them are 520 conversions. With that said, if you do a 520 rear sprocket and chain, you have to get the 520 front sprocket as well.

Now for which to choose...

The most common change is -1/+2. This removes one tooth off the front sprocket, and adds 2 to the rear. Adding 3 to the rear is the same as subtracting 1 from the front (so a -0/+5 is the same as -1/+2). You can get any sized sprocket you want, but the further you go from stock gearing, the more it will jack with your speedometer/odometer/top speed, etc. Find a speedohealer...they're a VERY good idea if you change your gearing. You'll be good with the stock length chain. Good luck!

I agree with everything Pilot said...

do the 520 conversion, save some weight. Do the 15/50 regear. get a speedohealer.

you will love it. And why people always talk about losing top end...I mean you lose like 5-7mph so you go 150 instead of 157. SO WHAT!! lol

I agree with Yoda... If you're going to do ANY sprocket change, you might as well swap them both out, and get yourself a new chain while you're at it. And the new X ring 520 chains are just as strong as almost ANY 530 on the market anyhow. Plus the chances of you snapping a 520 chain on a 600 cc bike are VERY slim, NOT IMPOSSIBLE, but very slim

If you're going to do the job yourself, you will need to have sockets (to take the sprocket off the rear wheel) A LARGE *I believe it's a 32 MM socket* and a breaker bar for the rear axle AND the front sprocket nut. A rear stand is quite handy to have. To break the chain you'll need a really good set of bolt cutters OR even better, a dremel tool with a cutting wheel on it. To put the new chain onto the bike, you will need a chain rivet tool. You will obviously need the regular allenwrenches and sockets to remove your lower fairings, antifreeze resevior, and front sprocket cover. Lastly... a good friend is ALWAYS handy when working on sprockets and chains because they can hold the rear brake for ya when you go to break that front sprocket loose, and help you with the other misc. stuff.
NEVER use a clip master link on a motorcycle... They will break eventually. If you can't get yourself a Chain Rivet Tool, you CAN put the clip link in TEMPORARILLY, but I would HIGHLY suggest that you take it to a shop as soon as possible to get a rivet link put on.

I just did the front sprocket only, and did -1. Kept the stock chain, and stock rear. Best way to ever spend $20 by far. Love it.

I prefer www.sprocketspecialists.com Their web site SUCKS, but their Products are GREAT and they ALWAYS have the sprockets/parts that they advertise. If you have ANY questions, they are able to answer them very quickly. If the persont you're talking to can't ansewer your question, they'll ask someone who can. Their Products are of VERY GOOD quality and seem to be VERY durable. I have been using their products on my bike for over 20,000 *twenty thousand* miles and never had ANY proplems what-so-ever.
I would suggest going with their Titan Tough coating. It hardens up the rear sprocket a bit, I have mine coated in Black, so it's all blacked out. But, that also makes the durability of your sprockets go up, and keeps them from bending, or rounding teeth sooner.

If you need help with their website, just PM me and I'll try to help you out with it.

I was looking at the Vortex pieces...they say they have the rears in 39T-50T, and the front from 14T to 18T. So, for the -1/+2 conversion I'd need the 15T front and the 50T rear with a new 520 chain?

Yes. That's what you're looking for. The chain, If you can find a 116 link, that's what you're going to need. BUT I would get a 120 link and just cut a couple links off. That way if you happen to need a little bit more (which you REALLY shouldn't) you'll have it.

I think I needed 118 when I did my 15 52 setup, but my 15 50 setup, I'm pretty sure that I just used the stock length 116 links, and it worked out just fine.

The only thing you have to be careful about with that is...

The 03-05 R6's Came with a 532 Chain. (no other year did that)

Most publications and shops will tell you it has a 530 on it. THEY ARE WRONG. It has the 532. I don't know why yamaha did this ... If you don't believe me check a few of the links on your stocker chain, they will have a #532 on them, but if you're going to stay with your stock chain, you must make sure to order 532 sprockets.

I think it's all around better just to replace everything at one time anyhow. You might as well do a 520 kit with the sprockets and chain any how.
