SUMMARY

The Model 31 CSR was a 650 'Café Racer'-styled parallel-twin developed by AMC to compete with BSA's Rocket Gold Star and Triumph's Bonneville. This 1960 example is in unrestored original condition and dry stored for a few years. Good base for a light restoration project.

DESCRIPTION

  • The AJS Model 31 CSR was a 650 'Café Racer'-styled twin-cylinder bike developed by Associated Motor Cycles (AMC) to compete with BSA's Rocket Gold Star and Triumph's Bonneville
  • The 'CSR' designation stood for Competition/Sport/Road, though it was also known as the 'Coffee Shop Racer'
  • It was powered by a 646cc, OHV parallel-twin with a stronger nodular iron, 3-bearing crankshaft to address prior vibration issues and, with upgraded camshafts and a distinctive 'Siamese' two-into-one exhaust system, power output was rated at 46bhp @ 6,500rpm
  • The engine was housed in a full cradle, tubular duplex frame with AMC's 'Teledraulic' telescopic forks in the front and a swinging arm with twin Girling shock absorbers in the rear
  • In 1960, the CSR proved its racing credibility when Ron Langston and Don Chapman won the prestigious Thruxton 500 endurance race on CSRs
  • This 1960 example is in unrestored original condition and has been garage stored for a significant amount of time. The engine turns over with compression but some recommissioning will be required
  • Supplied with a V5C registration document, dating certificate and some MOT history
  • A good base for a light restoration project
