Did some searching for different tooth sprockets for acceleration. but still not sure what to go for.

-1 on front? +1, +2, +3 on the back? or front and back together? people seem to have all different size's. What do other people have on their B1H?

Will i still be using a 520 chain if changing the sprocket size?

Thanx,

Paul. :Bike:

Can i choose any sprocket with 42 tooth? because when i searched on a website they they want your bike details it only brings up 40 tooth sprockets. if i type in zx10r it's 41 tooth. where can i get 42 tooth sprockets and what bikes are they mainly designed for? motorcross or something?

i'm interested in the Supersprox Stealth Rear Sprocket. but dont know if it comes in a 42.
is it ok to mix brands? renthal front, supersprox rear?

thanx!

the most popular is -1, +2. dont go too drastic though. I made the mistake of going by what someone said on another forum when i ordered mine, i suppose it was too much to put the Dos-X down and walk to the garage. (lesson learned) long story short i ended up going down 2 in the front and up 3 in the back. waaaaaay toooooooooo much. however........... the wheelie factor now is fun as hell!

If you want to go cheap(er) I picked up a 43T sprocket from an 05/06 zx6r and then went 14T in the front, I don't mind it, but you may need a longer chain (still a 520, just need 110 links instead of 108). -1 was good by itself though.

yes, with a +2 setup, its a substantial difference, but not too much it think it is perfect. but you will need to buy a longer chain, as well as a speedohealer or spedodrd

go -1 +2 its the optimum gearing for most zx6r riders. also you can still run this gearing with the factory size chain which is a 520 with 108 links.

Thanks for starting this thread Paul! Im on the same boat but I need sprocket and chain info for a 2005 ZX6R.
I've found some good info about pitch, chain and sprocket need to match.

I found this useful info on a webpage!

What’s the difference between 520, 525 and 530?

Pitch can be characterized by the thickness and weight of a chain. The first digit (5) indicates the center-to-center distance between chain pins. The second and third digits (20, 25, 30) indicate the chain’s width, measured between the inboard surfaces of the inner sideplates.

Because wider chains are typically stronger, the second and third digits also indicate a chain’s strength. Higher numbers correspond to greater strength, i.e. a 525 chain is stronger than a 520. This additional strength is achieved through increased roller diameter, pin diameter, pin length and plate thickness.

520
Will take the most weight off of your bike and will increase horsepower, however it is important to note that by decreasing pitch, you can expect faster wear especially on bigger bikes because the drive forces are getting spread over a slightly smaller surface area.

525
Middle of the road, standard chain that comes standard on most 600 and 750cc models. 525 is more durable, but heavier than a 520 conversion.

530
The heaviest, thickest and most durable chain pitch. Comes OEM on most 900- 1400cc models.
Don’t Forget! A worn or poorly maintained chain will wear an aluminum sprocket prematurely!

so i'm gonna have to look for a 520 rear sprocket to match the chain and front sprocket.

Hope this helps you too!:)

make sure it is a steel sprocket, cause aluminum sucks. the supersprox is supposed to get you the best of both worlds, but i just think it looks cool. and yes, with a +2 you will def need a new chain, i tried it lol. and i found that the speedo was approximately 9% off with the speedodrd conversion chart, with the speedodrd, it is now dead on. highly recommended

when you saying new chain, it's still a 520pitch with 108 links right?
Most people are saying i can use the same spec chain for -1/+2 conversion.

yeah, i have heard that especially those are garbage... they start disintegrating at 7k miles. if your buying the -1+2 you should be fine with the same length chain, but if you go only +2 you will need a new chain. i dont remember how long, i think i got a 118 and cut it down to the length. a speedo corrector is a must tho, otherwise your speedo will read 10-15 mph off and you will put more miles on your odometer
