Just wondering what the stock front and rear sizes are. Im thinking of switching them out and also would like to know what size everyone has gone to.

 

any respectable shop can tell ya... I just walked into my local, they know my bike. I just told em -1/+2 and had them installed 3 days later.... I've been counting stars everynight out since....

It seems to be common aggreance that a -1/+2 is the most common and well liked combo. Quick as hell, and you can keep the front tire down under hard accel if you want, or you can fly it as high as you have ***** enough too... I have a joe sprocket front and vortex rear and it cost me 90 bucks I think...

 

Theres no way im gonna let my stealership have my bike for 3 days....besides...why should I pay them when I can do it myself?

 

That's right. F the stealership.

 

Besides....the closest stealership is 130 or so miles away. Its easier for me to do my own work.

 

if your mechanically minded whatsoever changing the sprockets should be pretty easy. i know a lot of people do the -1/+2, but depepending on what kind of riding your doin, i only went -1 in front and i like it the way it is. i drag race a little here and there, but if i would have changed both, no way to keep front end down.

 

hey did you have to add or remove links from your chain for just the -1 in the front?

 

I did it myself, the thre days is just how long it took to get them shipped... With my -1/+2 I can keep the front tire down on the pavement if I so desire during a hard accel, maybe a tad bit of a power wheelie...

 

15 front/ 43 rear stock on the 05-06

15 front/ 40 rear stock on the 03-04

 

Here' what I saw on ebay from sum of all parts:

This combo fits all of the Kawasaki ZX6R and ZX636 models and increases power response across the rev range. Dyno tests prove that you can reach peak torque and HP an average of .4 seconds faster than stock!

Stock Sprocket sizes are 15 tooth front 40 tooth rear for the ZX6RR and 15 tooth front and 39 for the 636 which has a final drive ratio of 2.67 and 2.6 respectively. The optimum ratio for the 03 and 04 is 14 tooth front 42 tooth rear which has a final drive ratio of 3.00. The optimum ratio for the 05-06 model is 14 tooth front 45 tooth rear which has a final drive ratio of 3.21

Extensive testing on the street, eddy current dyno and on the race track have proven that this is the optimum ratio for your bike.
