Watsonian was a motorcycle produced in 1950.

  • The prototype had a 996 cc V-twin JAP engine. This had side valves and alloy heads and barrels which made it lighter. The engine was coupled to a Burman gearbox by a chain in an oil-bath case.
  • Dunlop telescopic forks were used at the front and, at the front and rear, large alloy hubs were used so that the motorcycle could stop quickly. The brakes were massive 9-inch drum.
  • The large battery was fitted behind the rear cylinder underneath the dualseat. The engine had coil ignition. Further to the rear was the oil tank situated between the right-hand chainstays.
  • It was an excellent sidecar machine but had limited appeal to the 1950s market and as JAP were not particularly interested in supplying engines to the project for this reason, the idea was not pursued. Only one machine was ever built.
