Good evening all,
I have coming to me soon a 1936 600 Aero, four speed, and according to the previous owner, it's quite "busy" and not overly quick but accelerates well, and first gear is probably superfluous as is. As it lacks a centre stand, I suspect it may have been a sidecar machine, and it is probably on sidecar gearing? Did Douglas offer alternative sprockets for these machines, and if so, which ones did they change from solo to sidecar, and what would the tooth count for each be please?
Many thanks
Doug
