Hi Martyn, I was thinking about your rear wheel again and was wondering what kind of offset was needed (if any) when lacing it up in the rim to fit the commando. Again outstanding build, CjMatchless said:...........The rear hub is 1978 Suzuki GS 550 but a CB750 F1 or a Z750/1000 could be made to fit with a similar amount of work..........Martyn.
