Description

1974 Norton 850 Commando Roadster
Registration no. HHX 450N
Frame no. 112960
Engine no. 318573

With its sloping engine, slim-line fuel tank, and upswept silencers, a black Roadster is surely one of Britain's most handsome motorcycles! Along with Norton's torque-y motor the Isolastic engine mounting guarantees a vibration-free ride...as soon as the revs exceed 2500 rpm. Is it any surprise the factory was unable to satisfy the huge in-period demand? HHX was purchased by a respected 2-wheel journalist, in Interstate form but, knowing how easy to effect a styling change, he soon found a like-minded Commando owner who was anxious to change his Roadster into an Interstate. A straightforward exchange then ensued, an exercise involving fuel tank, exhaust system, and side panels. QED! Fitted as purchased with a Boyer ignition the vendor continued to improve the specification, the main investment being a successful £2000+ rebuild of engine and gearbox by Mick Hemmings who, as part of the job spec, fitted lightweight fibre clutch plates, a belt drive, and PW3 cam. A pair of new Amals were also fitted. On the chassis side of things the menu includes Hagon-built wheels, an AP Lockheed caliper and master cylinder, Maxton fork internals and, amongst other sundries, a refurbished cradle and swinging arm bushes. Indeed, some of the above work was featured in Classic Motorcycle Mechanics, prompting the owners comment; "...there's tons of paperwork!" Anxious to retain the Commando's stock appearance he has deliberately always used TT100 tyres, resulting in a period Norton that's clearly above the norm. Supplied with V5C and MOT Certificate.
