1924 Quadrant 624cc

1924 Quadrant 624cc

In their comtemporary advertising Quadrant claim to be Britain's oldest motorcycle, the company was founded by W L Lloyd in 1901, the first models to his design were fitted with 211cc Minerva engines. The firm also produced the Quadrant forecar.

From 1903 onwards, Quadrant produced their own engines in a wide range of capabilities and types. The firm was represented in competitions for many years by Tom Silver and in May 1903, he was the only ebtrant to make a non-stop run in the SAC Glasgow-London Trial. This was described in the press report of the day as the most outstanding demonstration of the reliability of the motorcycle that has ever been made.

By 1924 Mark Newarch & Co Ltd owned Quadrant and was producing two models only - a 490cc and 624cc - both side valve singles, the 624cc model having been reduced from a previous 645cc engine.

These motorcycles had an enviable reputation as robust touring bikes but unfortunately manufacturing ceased in 1929.
