1942 Gilera Marte SWD

, Italy. Designers kept the engine of the LTE model, but raised its ratio of compression to 5:1 and got the increase in power to 14 h.p. However, if the engine was similar, the transmission mechanism was completely different. The first change was that the altered transmission came with a cardan drive for the rear wheel (instead of chain-and-sprocket drive). Spiral wheels were used in the gear box, but spur gears were used as well driving the cross shaft in front of the rear axle of the motorcycle. The second spur gear set was mounted in the sidecar wheel drive (most Gilera Marte motorcycles were three-wheel machines), and that made rear wheels work synchronously. The distributor box at the sidecar came with a cam clutch that was switched on with a cantilever on the motorcycle whenever it was necessary to activate the drive. #ww2 #worldwar2 #gilera  #gileramotorcycle #marte #italianbikes #history #motorcycle #instabike #instamoto #rarebikes #vintage #vintagemotorcycle #antique #retro #military #army #italianarmy #swd #sidecar #1940s #1942 #classic #classicmotorcycle #rare #war  #italiane #vintagebikeride #motor #militare
