The bike that is pictured is not a 1978 CZ 350 Twin. It looks to me to be a 1976 RV 400. A single cyl.388 cc reed valve engine built in Canada. The importer took 1974&1975 Falta replica bikes and rebuilt them by changing the tanks, pipes, shocks, fenders, and adding reed valves to them. This bike looks like it has the shocks moved forward and a Protopipe exhaust on it. Any questions please e-mail
