Humber Motorcycle 1920’s vintage motorcycle gearbox with kick start & 2-stud top frame mount
I had a similar one of these gearboxes before. The major difference was the frame mount. The other one clamped to dual lower rails and it was for Humber Flat Twin motorcycle. The gearbox sits under the rear cylinder. The model that I have seen it mounted to, is the Humber 4 1/2hp flat twin with a 3-speed gearbox and chain drive.
Having researched images of various Humber Motorcycles, it appears that this one might be for a Humber 350cc Side Valve single from around 1925 / 1926.
An image of a 1919 500cc model shows a different gearbox end cover. So, my best guess is that this is a 1920’s one. You decide if it’s right for your needs.
Distance between the mount studs is 4.5″ (centre to centre)
Anyway, if you’re looking for a good, vintage gearbox for a project, then this is a decent complete gearbox that will mount to the lower frame rails with the clamps. It would suit a medium to heavyweight motorcycle.
As I have not tested it, it is being sold as a box for rebuild. I would have it apart anyway, if only to re-lubricate and clean. It is not seized. The kickstart turns it over.
