Im going to get sprockets for my 636 and I was wondering how many teeth the stock front and rear sprockets are, and then what size should I get the new ones?

GundamnitPete

i know the stock rear is 40........that's all i know

Gixxer5988

thanks, even If i just know what to change them to, so that I know what to buy. I think Someone told me 1 down in the front and 2 up in the back but Im not sure.

WHEELIE

I don't know if there the Same As the ZX9R But Mine Are
16 Frnt and 40 RR

I just changed mine to 15 in frnt and 46 in RR.....:YEAH

depends on your skill level, IMHO you should be able to roll a nice idle wheelie on stock (or close to stock) sprockets.

if you can't do that on stock, then gearing up will only hold you back (make the throttle even more responsive)


there are two reasons for more gearing.

1. more engine brake
2. harder to stall on an idle wheelie.

if your not even using the engine brake, and you can't roll an idle wheelie, than there really isn't much of a point to gearing the bike now is there?

stock gearing for the 03-04 636 is 16 front 40 rear.

05-06 636 is 16 front 43 rear.

both are interchangeable.

a good street/stunt gearing for the 03-04 is stock front +10 rear (50 tooth) thats what i run. you could actually get away with +7 in the rear (47 tooth)

hit me up if your trying to ride

That is incorrect! Ive got 3 636's here 1 2003 and 2 04's and they all came with a 15 tooth front sprocket stock.

I wouldnt go any smaller than 15 on the front, most 600's come 16 tooth stock but the 636 already comes 15 I wouldnt want a 14 on there.....Too small IMO

the great thing about 636's is that you can rock them with NO gearing or with TONS of gearing, whatever is your preferance! and it will work great with either!

I have a stunt/show bike that i have -1+10, and i want to go a little more with it. I also have a streeter with stock gearing that I can do ALL of my tricks on, including combo HB O's and sitdown (yes foot UP) O's and all of my on the tank stuff on. you just have to rock the idle lower and work the clutch better if you have less gearing

T-NECK

yes your right! it was a late night last night..lol

I went -2 + 8 on my2005 ZZR600 and I friggin' hate it. going back to -1 +2 !

Sparky88

Currently running +10 and have just ordered a +15

I'll also go up 1 tooth in the front as my current set up seems to slaughter front sprockets

PETERPAN

What size chain do I need for my 04 zx6r if I run a stock 15 front and vortex 50 rear?
