I am a relatively new CBR owner and it is time for me to replace the chain. Does anyone have any suggestions of the type of chain (brand, size i.e. 520 525, 530...) or the best website that I can find one. I have done some research myself and I know that I need to replace the sprockets along with the chain for my sprockets are worn so I would like to buy them as a set for this seems to be the most economical way of doing it. I keep find RK chains and I cannot seem to be able to tell the difference between the silver and gold. If I should not even consider RK as a brand that is fine just suggest one that is better and won't break the bank. I appreciate the help.

 

the 520, 525, 530 refer to chain strength. As far as the silver and gold, I think its just for aesthetic appeal.

 

520, 525 and 530 refer not to strength but chain size. All things being equal, a 530 will be stronger than a 525, and both will be stronger than a 520. However, a more expensive 520 can be stronger than a low end 530. RK makes good chains, as does DID. Since you need sprockets, I would get a 520 chain/sprocket kit. Get an X-ring chain if you can, but an O-ring chain will also work well. A good 520 chain will have more than an 8000 lb tensile strength, which is well more than you need for an F2. The 520 will reduce the moment of inertia of your rotating assembly (wheels, engine, etc...), and that will improve acceleration. It will be a tiny increase, but every bit helps.

Make sure you set your tension well and lube up that new chain nicely or else that $140+ you spend on your chain and sprocket kit will be wasted! Also, have you considered changing the final drive ratio? If you need sprockets, now's the time to do it.

 

What is the final drive ratio?

 

Never mind I found it
