i have a 00 cbr929rr and it's time for a new chain and sprocket and would like to upgrade from my stock parts. I have limited experience in this area and would like some imput. I'm looking at a RK racing chain and sprocket kit which includes a 15/43 sprocket set up and a 2.87 ratio (not sure what that means) and a GB520GXW-108 chain. Any input will be helpful...this a good set up for street riding. Thought it would be better to get a package deal instead of ordering a vortex sprocket and rk chain seperate...thanks.

 

personally.. i hate RK chains. DID is the way to go, they last twice as long in my own experience. (and if you dont know, a 520 chain is a lot smaller than a stock 530 size chain. which means it will wear out a lot faster)
vortex make the best sprockets (for street riding.)
i dont know of any places off hand that would do a package deal, other than check ebay.. that place usually has some.

(and i might be wrong, but you might need an extra link in your chain. stock gearing is 16/41 if i am not mistaken... you said you are going -1/+2.. so i think you'll need an extra link...maybe..)

 

I believe the 929 came with a 16/43 if it is true then he is only -1 in front so he does not need to add any links.I would suggest going with the 530 chain, 520 does wear out much faster.

 

thanks for the imput i'll look into a DID 530 and vortex sprockets as far as the 15/43 that fine or should i look into a different combo...i need something is versital because i do like hitting the curves on the streets but i also like to pull out some wheelies on the straights.

 

Steel front sprocket, aluminum back sprocket. 520 conversion isn't as bad as many say. Consider a TSUBAKI chain. They are more pricey, but if you do go to the 520 conversion, it will wear equally to that of stock chain/sprocket combo.

By going -1 in the front, you won't loose that many rpms/top speed. It will definitely help with torque in that one higher gear going around corners and can handle up to about a 70mph second gear clutch up. Converting to the 520 will reduce rotational mass but will sacrifice a little longevity on chain life. I had the 520 conversion 15/45 on my old 929 and put down about 6,000 miles and sold it with everything still being in great shape. As long as it's o-ring or better, and it has a high tinsle strenth, you'll be good to go. With the 15/43 no longer chain is needed. You can go -1 in front and upto +3 in rear and won't need a longer chain.

Have fun.

 

how many links should i be looking at 120?
