1953 Archer Norton Scrambler
Previous Image | Next Image
Description: This is an early example of a purpose-built motocross racer. Ridden by Les Archer, it was created at his family’s garage. The original Archer Norton scrambler, powered by a 500cc ohc Manx racing engine, won first time out in 1952. Norton approved, freely helping Archer build four team bikes to represent the marque. Archers’ mechanic Ron Hankins, modified the Norton frames.  He converted them to a single top tube, braced the steering head and altered the downtubes to suit a 21in front wheel.  Long-stroke Manx engines were installed with four-speed gearboxes.  Cylinder bore wear was heavy on sandy circuits, so a plated nikasil cylinder barrel was obtained from Mahle in Germany.  Archer Nortons enjoyed many successes and Archer was European motocross champion in 1956.  In the Sixties, he built a motocrosser with the later short-stroke Manx engine, but this is the sole survivor from the Fifties.
Engine: 499cc (79.62 x 100mm) ohc single, compression ratio 9:1, (variable), Amal TT carburettor, twin-spark magneto ignition.  Power: 32hp at 7,000rpm. Weight: 340lbs Top speed: 85mph.
