Lot Details
1958 Royal Enfield 693cc Constellation
Frame no. 9676
Engine no. SB10367
Like BSA and Triumph before it, Royal Enfield went on to enlarge its 500cc twin, eclipsing its rivals with the 700cc Meteor, Britain's largest vertical twin at the time of its introduction for 1953. The crankcase remained fundamentally unchanged but the bore/stroke dimensions and engine top-end were those of the 350 Bullet, doubled up and restyled. Extensive revisions to the engine and the adoption of a new frame (shared by the Bullet singles) ushered in the Super Meteor in the autumn of 1955. While the Super Meteor was a fine performer, Enfield's next development - the Constellation - was outstanding. Based on its immediate predecessor, the new sportster featured a 51bhp engine, revised frame and a handsome 4.25-gallon fuel tank. On test with Motor Cycling magazine in Belgium, a Constellation recorded a top speed of 115mph while averaging 51mpg, impressive figures by any standard.

This example of one of Britain's rarer parallel twins was purchased at auction in 2001. Totally restored that same year, it has been on museum display in the Isle of Man since then and has been started but never used. Described as in 'A1' condition, the machine will require the customary safety checks, re-commissioning and a new 12-volt battery before use. There are no documents with this Lot.
