Georges Roy began motorcycle production with an unorthodox ‘New Motorcycle’ with a pressed steel chassis, then moved further from the mainstream, beginning production of the hub-center steered Majestic in 1929. The machine is a brilliant Art Deco sculpture, with a swooping unbroken line from the curved front wheel beak to the sporty abbreviated tail. The side panels are punctuated by louvers like a racing car (and the bike pictured is painted Bugatti / French racing blue). As the entire chassis is pressed thin-gauge steel, the overall weight is fairly low – I would estimate from hefting and pushing one around that it weighs 350lb. The chassis is constructed using two mirror-image side pressings, rivetted together by firewalls at the front and back of the engine, with further strengthening panels beneath the engine, plus the two large, fixed top panels. The whole structure, much like a monocoque car (or a late Cosworth /Norton racer), is extremely rigid. The central engine cover is removable for access) …, and … the side members are totally louvered to keep the engine cool. There’s plenty of room in the engine bay for a large motor, or even a radiator for a water-cooled machine. The petrol tank sits under the front bulkhead.
