Topic: 520 O-ring chain conversion for CB-550?

[scooterplooker]

I’m getting down to the final stages of my CB550 resto-mod, and was wondering what the easiest way to do a 520 conversion? Does anyone sell a ready-to-go kit that is a direct stock replacement? Would that allow me to use a 520 O-ring chain without chewing up my crankcase?  Thanks in advance, this forum is great!

These folks sell a rear 520 sprocket as well as the front, and an offset version if you go with wider rims.

Question about the 520 chain and sprocket swap without the offset sprocket, is it a direct
Fitment for a stock wheel base 550 with upgraded O-ring chain.?  No other modifications needed.? Not hi jacking your thread, just wanted to hear some additional info o the swap.
