The BSA Model E was the first of a series of successful V-twins [1] based around the reliable 770cc side valve engine with cylinders at an angle of 50 degrees. The modest 6hp produced by the engine was able to provide a top speed of 55mph and it had BSA's own design of three speed gearbox with the drive chain enclosed in an aluminium casing.
The design of the Super X was a considerable departure from its predecessors at Excelsior. Where earlier Excelsiors had an enclosed primary chain transmitting power from the engine to a separate gearbox, the Super X had the engine and transmission together in a single crankcase, using a helical gear to power the transmission directly from the engine.

The mainstay of Excelsior production through the 1910s and into the 1920s was the 61 cu in (1,000 cc) Model BigX. This had an inlet-over-exhaust v-twin engine, first with belt drive then with 2 speed and then 3 speed gearbox. Colors were grey with red panels in the early teens, the 'Military Model' of the late teens was in khaki (a green-brown ...
The Matchless Model X was developed for V-twin enthusiasts and had a specially reinforced rear frame for heavy-duty sidecar work. At the end of 1936 the Model X was upgraded and rebranded the Sports Tourist, with a shorter wheelbase frame which improved roadholding and steering.
It was named "Powerplus" because its output of approximately 16 horsepower (12 kW) was noticeably greater than that of the earlier engine. [4] The new engine was installed in the existing frames for Indian V-twin motorcycles, and used existing drivetrain components, tanks, handlebars, and other components. [3]
Indian Scout. Model G-20. Designed by Charles B. Franklin, [1] [3] the Scout was introduced in October 1919 as a 1920 model. The Scout had a sidevalve V-twin engine with its transmission bolted to the engine casing, allowing a geared primary drive - the only American v-twin to use this maintenance-free system. [4]
The engine was of its own manufacture. Some may have had the earlier V-twin engine fitted. After the First World War, in 1921, it was re-released as a 10 hp with a 1315 cc engine and three-speed gearbox. The two-seater version cost £350, later falling to £300. A few hundred were produced with the last made in 1922. [7]
