sprocket question (cb550/750)

[Bert Jan]

Hi,

Recently converted a 750f2 to spoked wheels, using a cb550 wheelset. I am in search of either a 630/cb550 rear sprocket or a 530/cb750 front sprocket.
the OEM 630 sprocket does not fit the 550 hub, and the OEM cb550 rear sprocket obviously wont mount to a 630 chain. The 750 has a 630 front sprocket.

No need to begin stories about some 750's having spokes OEM. They were made, but had disk brake. Customer insisted on drumbrake, so therefor i picked a 550 wheelset.

Anybody got the trick?

Never mind, got it. CB650z has same output shaft as 750 but 530 chain. So 650z frontsprocket it is and 530 chain.

Bert, I always head over to JT Sprocket's website and browse their online catalog. They have all the dimensions and spline sizes listed for every sprocket they sell.

Not much help now, but it might come in handy later...
