This was quite a while back! 836 Bore.. John Harman frame. Front wheel hub converted to rear wheel with disc brake. Machined sprocket and new rotor mount to adapt to hub. Many parts I custom built (handlebars, foot pegs, rear backrest and more. In the 70's there was a company that had a very small dry battery with electronics that eliminated the stock battery.. so it was kick start all the way. Removed the starter and mounted the coils where the starter used to be. VERY light bike...! Hallmark dual disc front wheel. These are pretty much all the pics I have of this bike. It along with everything else we owned was stolen in 1976.
