I am going over the parts around the rear wheel bearings and replacing what is needed.
is there a difference between the 2 part #'s I listed above or are they the same thing.

in the online parts manual they are both listed for my bike.
I'm confused.

BUT the part ending in 770 is no longer available.

parts 4 and 5.
and my bike is a 7L.

thanks.

Part number 42312-KV3-770 does not supercede to 700 or vice versa so there is no way of knowing if they are the same.

The part you need is dependant on your frame number.

If your frame number is below 1014675 then you need 770

If your frame number is above 1014676 then you need 700
