hell yea

1937 ss 250 split single These engines also have a Ladepumpe under the the engine, which is a separate cylinder used to compress air into the crankcase - a kind of supercharger for two-strokes. Thus, while this motorcycle is technically a twin-cylinder two stroke, mechanically it is a 5-piston machine - hardly a 'simple two-stroke

this should be easy

dkw supercharged 250/350 1936/40 by the looks Possibly the most aesthetically pleasing, most advanced & fastest prewar light motorcycles of all time..The supercharged deeks led to the banning of supercharging in racing grand prix & TT machines ,,,ps built a plastic model of one when i was a kid lol

Bicycles and motorcycles[edit] Glenn Curtiss on his V8 motorcycle in 1907 Curtiss began his career as a Western Union bicycle messenger, a bicycle racer, and bicycle shop owner. In 1901 he developed an interest in motorcycles when internal combustion engines became more available. In 1902 Curtiss began manufacturing motorcycles with his own single-cylinder engines. His first motorcycle's carburetor was adapted from a tomato soup can containing a gauze screen to pull the gasoline up via capillary action.[2][3][4] In 1903 he set a motorcycle land speed record at 64 miles per hour (103 km/h) for one mile (1.6 km). When E.H. Corson of the Hendee Mfg Co (manufacturers of Indian motorcycles) visited Hammondsport in July 1904, he was amazed that the entire Curtiss motorcycle enterprise was located in the back room of the modest "shop". Corson's motorcycles had just been trounced the week before by "Hell Rider" Curtiss in an endurance race from New York to Cambridge, Maryland.[5] In 1907, Curtiss set an unofficial world record of 136.36 miles per hour (219.45 km/h), on a 40 horsepower (30 kW) 269 cu in (4,410 cc) V8-powered motorcycle of his own design and construction. The air-cooled F-head engine was intended for use in aircraft.[6] He would remain "the fastest man in the world," to use the title the newspapers gave him, until 1911,[7] and his motorcycle record was not broken until 1930. This motorcycle is now in the Smithsonian Institution.[8] Curtiss's success at racing strengthened his reputation as a leading maker of high-performance motorcycles and engines.[9]
