I just picked up a 2000 929 CBR and it seems to be geared real low. The rear sprocket has 55 teeth on it. The bike screams when I am on the highway. I don't really know how fast i am going, but I figure it is about 200km at 11,000 RPM. I would like to know what tooth count a stock sprocket is for the bike and if anybody knows what a slight mod from stock would be, or if anybody has found a decent combo for the bike. Thanks

 

i have an '01 929 and im sure there the same. Stock it come with 16 teeth on the front and 43 on the rear. I have gone with a 15 and 43 setup just for a little extra torque. I didnt want to be screaming on the highway or kill my mileage cause I do a lot of commuting. But I still wanted that little boost for when Im out playin.

 

I have the same setup as Hooligan, and it works well for me. Picks the front up when I want it to pretty easily. I went ahead and bought a Speedohealer as well to correct the 11% that mine was off after the mod. Yours must be outragiously off!!! LOL That was probably a stunt bike, so never saw the highway.

How much different is the feeling of your bike from stock? How much does it change your mpg? Speedometer?

Thanks

 

Last question already answered....11%

Feeling is a lot better in first three gears. Don't mess with 1st...it's crazy, lol

I don't know about the MPG. I know I run at about 500 more rpms at 70-75 mph

 

thats a stunt sprocket.......thats why she screams..........

 

I average just under 40 mpg. Depending of course aggressiveness and highway versus city. I love 1st gear I think its a riot but you gotta be ready for it cause it could easily kick your ***. I never rode it with stock gearing but it feels good in all gears. Like I think I said before I do a lot of highway commuting and I can cruise all day at 80 comfortably.

 

Thanks guys, I will probably go with the same set-up I found the RK Quick Acceleration kit. FITS MODEL: CBR929RR 00-01, CHAIN: 520GXW-108, OEM GEARING: 16-43, QUICK ACCELERATION GEARING: 15-43

It is cheaper then if I go with the stock set-up... about $170

But I will be waiting a bit I want to see how much more I can milk the chain I have with 17,000 miles. I picked up the grunge brush today

 

If I were you I'd stick with the 530 pitch it will last alot longer than the 520 pitch.Yes change your sprockets to 15-43 but stay with the 530 size.

 

Stock sprockets:

U.S.- 16/43

Anywhere else- 16/42

15/45 works well and I am very impressed with this setup
