I need a new chain for my cb750 and was wanting to clear something up. I've been asking my friends about it and some say xring/ oring/ whatever other type of ring chains vs standard chain. Anyways some say that the ring chains have alot of powerless and others say they don't. Any chance their is some documentation on the subject or any opinions? Really don't mind spending the extra cash to get the better chain. O and any suggestions on brands and models?

 

Theres no power loss between chains, i saw some numbers on a site once and the most was like .4 hp or less i think which is completely negligible, i forget where it was though. Most people go with did or rk chains. Theyre fairly cheap and pretty good. Most people recommend the xring chains as well since they have two sealing points and seal better so the inside is practically lubed for the life of the chain and doesnt get as dirty inside either.

 

wow i was expecting to see a few hp loss. from what i was reading it has something to do with the chain takes slightly longer to warm up but once it does it runs the same. and thanks for the suggestion. i have been looking at some did x-ring chains. thanks for the help

 

You should replace your sprockets too when you put on a new chain. I just did mine on my f4i and got a RK chain and sprocket kit from denniskirk.com.

 

Xring chains are good chains. Many guys suggest replacing sprockets with chains, but if you are not make sure the teeth are not worn down. Bad sprockets will eat an expensive new chain up. And be sure the chain fits the sprockets. A 520 chain wont fit 530 sprockets, as an example...

 

When "new" there is absolutely more parasitic loss from an oring chain then a non oring chain. A standard chain contributes about 2% to parasitic loss. A typical o ring chain is somewhere around twice that and a modified o ring (x) are generally about half the loss of a typical oring.

In any case , those or hardly significant numbers and your more likely notice loss from under inflated tires, which 99% of the riders out there now are on than the chain.

Bottom line, for a street bike you want an oring chain, regardless of ring type. Your preference there.

 

You'll be fine w/ either x-ring or o-ring.

D.I.D & RK are Honda OEM suppliers & are both excellent chains. I've run both on all my bikes.
