- Levis (motorcycle)
Levis motorcycles (1911 - 1940 ), manufactured by Butterfields of Birmingham, were for many years one of England's leading manufacturers of two-stroke motorcycles. They built two-stroke machines from 1911, and added a line of four-strokes in 1928, that ran to 1941 when production ceased.
The first Levis was made in the Norton works by designer Bob Newey, but James Norton turned it down.
Newey then joined with the Butterfields, Arthur and Billy, and sister Daisy, to set up a motorcycle company. ( Newey later married Daisy.) Their first model had a capacity of 211 cc.
Two Strokes
In 1916 the 211 cc vertical two-stroke engine produced convert|3|hp|abbr=on. An enclosed chain from the crankshaft drove the Fellows magneto and drive to the rear wheel was by Pedley ‘Vee’ belt. The machine weighed approximately convert|120|lb|abbr=on. [ [http://www.scienceandsociety.co.uk/results.asp?

Their first racing success was in the 1920 Lightweight 250 class within the
1920 Isle of Man TT Junior with a 247 cc machine, repeated in the1922 Isle of Man TT Lightweight race. They then adopted the slogan, "The Master Two Stroke".Levis built 211 cc and 246 cc three port single cylinder machines, including sporting versions. Most had convert|67|mm|in|1|abbr=on bore and convert|70|mm|in|1|abbr=on stroke. There was also a six port model.

Four Strokes
From 1928 onward Levis produced 247 cc (convert|67|mm|in|1|abbr=on bore x convert|70|mm|in|1|abbr=on stroke) and 346 cc (70 mm bore x 9O mm stroke) four stroke ohv machines and later added 498 cc and 600 cc ohv four strokes. For a brief period a 346 cc sv single, and also a 247 cc sohc single with chain driven overhead camshafts were available.
Competition
Levis two strokes, ridden by Geoff Davison, R. O. Clark, Phil Pike and others, won many races including the 1922 Lightweight TT, while the four strokes excelled off road. Percy Hunt rode a 346 cc model successfully in races, and just before WWII Bob Foster gained many wins on a Levis ohv 598 cc bike in trials and moto cross.
Other Two-Stroke manufacturers include Scott and Villiers.
