I just wanted to know what is the difference between the 520 and the stock chain. Like what benefits does one have over the other if their is any? Thanks

^^^^^^^Yeah what he said, but it's for a reason with a lighter chain you have less unsprung weight, it gives you acceleration advantages. If I'm correct you have a 530 or 535 stock I forget which one it is. But with a lighter chain you'll have a shorter chain life, as long as you buy a good brand it shouldn't be too bad. That and people usual get a sprocket conversion w/a 520 chain. my 2 cents, yay

And most importantly, corner advantages.

your stock 06 R6 chain is a 525. not much heavier than a 520 setup. unless you are radically changing your gearing or racing and every little bit helps, your stock chain with a -1/+1 sprocket setup will cost you less, last longer and provide all the gear you will ever need on all but the tightest of roads. good luck and if you choose a new chain, be sure and get the press on master link and not the clip style. they are much safer.

sorry for jacking this thread. but i am confused with all this gearing and stuff. i want a 520 conversion for my 06, and i want to have more power lower down. so to sacrifice the top end speed. what gearing am i looking for in relation to +/- front or rear sprocket. i am here over in the uk, and i cannot find anyone that sells the conversion kits for my bike. they all sell up to 05 only. so any hlep on where to get the sprocket and chain from would also be appreciated, thnx

indysuperbikes.com sells 520 conversions, as do motomummy.com, sprocketspecialists.com and many others.

for your 06 R6 I would suggest dropping no more teeth in the front than 1(this is equivalent to adding 2.6 or something to the rear in theory). Beyond that you will get different forum members saying different things. I personally think -1 up front with +1 in the rear gets the job done quite nicely for the street. You lose a little top end which shouldnt even be noticable on the street as most of us dont drive that fast anyhow but you gain a noticable punch off the bottom. If you are going in this direction, you could get away with using the stock chain and just buy 525 sprockets. If you choose to buy any larger rear sprocket than this though you will need a longer chain and while you're buying you may as well drop down to a 520 chain pitch with 520 sprockets to match. I have heard of guys going -1/+3 but I could not see how that would be good for anything other than really tight roads/really tight tracks. Good luck with your decision.

only if you change your gearing it will. so if you change the teeth on your sprocket it will. you can buy a speedohealer to correct your speedo after you do the gearing change though. a speedohealer just changes the speedo up or down a % which then will correct it.

I dont know about the europe/american exchange rate but, i picked up the Rk gold chain, Vortex rear sprocket(50 tooth), and a JT 16 tooth front sprocket and it all came out to about 150. $90 for the chain, 45 for the vortex, and 15 for the JT. i wouldnt bother going high end front sprocket. The difference between the Vortex and the JT front sprocket is minimal and you will save 10-15$ by going with the JT. oh ya and im more than happy with this set up. My speedo right now is exactly off 5 miles an hour but it gets the front wheel up stupidly quick compared to how the stock gearing was. I dont know why the hell Yamaha decided to go with 532 on there r6's instead of 525 :thumbdown

i actually got mine from my friend over at HAI. its a bike shop here in central florida. but if your looking for cheap parts, I highly recommend you get an Ebay account. Ebay shoppers save themselves Hundreds of dollars. I pick up 95% of my parts there. If your going to get an ebay account also. I recommend you get a paypal account. It's the safer alternative to paying for your parts, and it ensures you wont get ripped off or falsely advertised parts. heres a link to a good deal, maybe something ur looking for;

also, alot of auctions advertise as shipping to the US only. If you PM them, most of the time they will agree to ship over seas as long as you pay the true difference for the actual shipment. so for example if it's advertised as $20.00 shipping, you might have to pay $25 or $30.

Except for a bit higher RPM on the highway, it's great for the street. A bit torquier feel, and better acceleration. Unless you plan to run 100mph on the highway all the time, -1 +3 is the way to go IMO. To me a stock R6 feels like a slouch now.
