No neither one of those wheels is a drum wheel
The wheel on the left looks like a CB750F wheel that has a rear disc. its 18in
The wheel on the right is a front wheel for a CB750 K or F are the same as far as i know but not 100% sure. its 19in
I would assume that since the rear is for a CB750F that the front would also work on a F.
Ill look at the my wheels latter and see if the front on my K is the same number as the one on my F
They are your wheels or wheels that you are thinking about buying?
A question... will these Lester's work as is on a 1978 CB750F? I've got a line on one I discuss in another post... if so, anyone need a set of Comstars?
No
The only thing bike that they will just straight bolt on to would be a 1975-1976 CB750F
The thing is that front wheel, its a 6 bolt rotor.
What that means is that the front wheel will only go where other 6 bolt rotor wheels were.
The only wheels that have a 6 bolt rotors are spoked so it will not bolt onto the 77-78 F forks that should have comstars(5 bolt rotors)
Yes things might be able to be made to work with spacers and what not but im talking about using them as bolt on OEM wheel replacements
The rear wheel will bolt on to a 1975-1978 F
