Watsonian
From Graces Guide
This company produced its first machine in 1950.
- The first prototype had a 996 cc V-twin J.A.P 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 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 J.A.P were not particularly interested in supplying engines to the project for this reason, the idea was not pursued.
