History

In November 1975 Guzzi unveiled the 850 Le Mans, a fierce sports bike based on the 750 S3. With 36 mm accelerator-pump carburettors and open bellmouths it made about 71 hp and could reach around 209 km/h. Just over 7,000 first-series bikes were built, with small differences between series A, B and C.

The Le Mans II of 1978 got a three-piece fairing with built-in indicators, a rectangular headlight, the 1000 SP dashboard and Nigusil-coated cylinders. In the US there was also the CX100 with the 1000 cc engine.

What to check when buying

  • The Le Mans I seat cracks easily, and black-painted parts such as the exhausts rust. Look closely at the finish.
  • An original Le Mans I is valuable. Check the numbers, the small headlight fairing and the original parts.
  • Test the linked brakes and the riding position.
  • Check the Nigusil cylinders of the Mk II for wear.
  • Listen to the timing gear and ask when valves and carburettors were last set up.
