3 inch rear rim

[r1_pete]

I'm thinking of going for a 3" x 18 rear rim on my F2, its running an F1 Spoked rim.

Has anyone used a 3" rim on any CB750? if so what tyre size have you gone with, I'm looking at 120 80, or 130 70?

Cheers.

I don't know if this is any help Pete, I've got a CBX750 that runs a 3.0inch rear rim as standard with a 130/80 tyre fitted. Currently a Bridgstone BT45 and it measures 129mm across the shoulders (widest point) when fitted/inflated.

Closest point of contact is the shoulder to chain-guard or chain run, may help you have a measure on your F1 fitment.

Cheers, I'll have a measure up, I've bought a 3" rim, but have a little lateral movement on the spokes.

I dunno about the rim but I have a 130/80 on my 550.
