look in the tech section, there are many threads on sprocket changes etc.

as you may know, changing sprockets will not add any more power to the bike, the conversion simply delivers the power faster.

All my opinion, but it worked well for me:

1. You should get a new chain, dont put the old chain on your nice new sprockets, youll have to cut it to the correct size, they come in one long strand that you size yourself. Its pretty easy, just count the links on the stock chain, and match the number of links on the new chain. 520 is lighter (faster accel) than the 525 you have on there right now. unless your at the track, you probably are ok with another 525 chain. its up to you, i got a 520 because it was cool. i didnt notice it was lighter or anything.

2. Go -1/+2. One tooth less on the countershaft sproket (the front one), two up on the back sprocket. its a little aggressive. your rev's are gonna be higher as you cruise down the road, and your speedo will be slightly off, but youll accel. really nice. when you pin the throttle youll notice the bike takes off.

3. i wouldnt get aluminum sprockets, i tore the teeth off mine. look for steel ones. the steel is a little heavier, but its stronger, and you are less likely to tear teeth off. when (if) your doing a wheelie or hauling ass down the freeway, tearing a tooth off your sprocket is not cool.

maybe a package like this would work for you, i just chose random parts, stuff i used on my bike:
DID xring 520 chain:


stealth rear sproket (aluminum but with steel teeth, thats cool):


afam sprocket:


thats how i did it anyway. maybe you would have better luck with the vortex aluminum sprocket or some other setup, but i tore through it so fast i told myself i wouldnt get another aluminum one.

you may want to get a speedo healer ($90 +/-). it lets you adjust your speedo. so if your going 25mph, it indicates 25mph on your display. this is nice when you have a pig behind you and your not really sure how fast you are going. the new gears will throw off your speedo.

You also may want to get a chain tool ($100)to size your new chain. Sizing a chain is pretty easy. I did it with zero exp.:


I know it's a litle extra money for the tools, but its worth it. you can swap back to your stock set up, and try different sprocket/chain combo's without having to pay someone else. if its gonna be a one time switch, you may want to borrow a chain tool since $100 is kinda expensive for a one time use. there are cheaper tool kits out there, but with some tools, its nice to buy a decent kit. i got a cheap chain tool kit in the past, and ended up throwing it away.

frontplayer summed it up very well. I did the +1/-2 with a 520 chain last fall on my '08.

I am not a certified mechanic but I work on my car, truck and all my bikes and it was very easy and self explanatory.

I ordered all my parts from www.sportbiketrackgear.com they are a dealer on this site. I am a local guy so they helped me out on everything. I would give them a call or piece everything you need together on your own. Let us know what you do.

Well first off, if your bike is new then you prolly have less than 500 miles on youre bike, if that. you have no need to switch to a 520 chain. a 525 chain is a lil bigger but its a lot stronger and less prone to stretching(why would the factory put on a 525 if it was meant to have a 520?). I would go with a 1 down in the front, 2 up in the rear setup, and the beauty of this is that your stock chain will still fit like it did before since youre losing a tooth up front. I dont know why people say to get a new chain unless you already have like 3k miles on the bike. no one on the street needs a 520 kit, but everyone says they do. plus, if you just change your sprockets you save about $200 because youre not buying a chain and a chain tool. Well do what you want but this is prolly the smartest and cheapest way to go.

So if you have a new chain already why not keep it? makes no sense at all
Do not see where he says it’s a new chain. Just cause it’s an 08 it still could have some good mileage on it. I am just saying what I would do. When I replace my plugs in my truck I do new wires and caps as well just to be safe. If he is already pulling the old shyt off take the time and 100 or so dollars to do it all @ one time. (well I am not sure how much the tool cost so prob more like 200 for the chain and tool kit) then he has the tool to change any of his bud’s chains ect… prob will even end up making money back out of the tool if he charges 10-20 bucks a time

I'm not sure what people are doing to rip aluminum sprockets apart? I've always used them. My 1000 currently has 17,000 on the aluminum rear and it's fine. The one before that lasted 20,000. The chain was actually shot before the sprockets.
Perhaps too many whoolies? :headshake

I've heard the aluminum sprockets tend to rip teeth. I havent heard of 20k on an aluminum sprocket before. Like i said, for some people different setups work better. :thumbup:

I guess if your chain is brand new you wouldnt have to replace it after installing new sprockets. Keep in mind an old chain with new sprockets can cause stuff to wear quicker. Why risk it?

If your chain snaps or your sprockets fail in the middle of no where, mid corner, during a wheelie, during a trackday, you could possibly crash and cause over $1,000 in damage to your bike or worse still, hurt yourself (around here an ambulance ride is $1,000just to get to the hospital). Just because you break something doesnt mean you will crash of course, but you could.

IMHO: I think you should buy nice stuff and do the mod with all brand new parts. Not with new sprockets and a chain with 2,000 miles on it.
