With the AJS 7R, the British company was returning to post-war life the only way it knew how – racing. The 7R debuted in 1948 with a 348cc engine and often punched above its weight, pumping out 30 hp and weighing about 300 lbs, both numbers rather competitive for its day. It was so competitive, in fact, that Les Graham won the Swiss Grand Prix in 1950 aboard one, beating out the likes of Norton and Moto Guzzi. Privateers continued on with the 7R well into the 1960s, where constant development enabled the bike to remain competitive at the national level.
