The Thruxton 500 was a 500 mile motorcycle endurance race held at Thruxton Circuit, near Andover in Hampshire, United Kingdom organised by the late Neville Goss, M.B.E., Clerk of the Course of the Southampton and District Motor Cycle Club.
As a production-event for road-based bikes ridden by a team of two riders per machine, in the 1960s the Thruxton 500 race was very important to British motorcycle manufacturers as it was a 500-mile (800 km) test of their bikes which provided public-exposure. A win, or second and third places in the Thruxton 500 offered advertising opportunities and boosted sales, so there was keen competition around the fast and demanding track.
Similar events were the Bemsee-organised Hutchinson 100 at Silverstone and the 'Motor Cycle' 500 at Brands Hatch in 1966 where Mike Hailwood demonstrated a Honda CB450 Black Bomber fitted with a sports fairing. It was unable to compete in the 500cc category, the FIM deeming it was not classified as a production machine as it had two overhead camshafts.
Only one motorcycle race a year is now held at Thruxton - a round of the British Superbike Championship
As with many World War II airfields, RAF Thruxton found a new role in the 1950s as a motorcycle racing circuit. Declared surplus to RAF requirements in 1946, the early track included both the runways and perimeter roads. The first race at Thruxton was organised by the Bristol Motorcycle and Light Car Club and took place on 4 August 1952. In 1953, a longer circuit was used but in 1968 the British Automobile Racing Club took over the track and on 1 March 1958 the 2.35 miles (3.78 km) circuit, which is still in use to this day, saw its first race.[not in citation given]
Racing at Thruxton became famous for the endurance events for production motorcycles, and the Thruxton 500 in particular. The bikes were supposed to be the same as could be bought, but most factories of the time invested in a racing team that invariably developed the bikes as much as possible.
Due to the long distance, the 500-mile race (originally known as the Thruxton 9 hour race) was normally shared between two riders.
Motorcycle racing continued on the bumpy wartime tarmac (which was slowly breaking) until 1965, when plans were agreed for a new track. The new layout ignored the original runways and followed the perimeter road with an added chicane and three tight corners in succession (named Campbell, Cobb and Segrave) which became referred to as the complex.

Triumph at Thruxton
The Triumph Thruxton 900 is a motorcycle made by Triumph Motorcycles Ltd. Launched in 2004, it was named after the Thruxton Circuit where Triumph won the first three places in 1969, establishing the "cafe racer" era where standard production motorcycles were modified to improve racing performance.
Nortons at Thruxton
In 1969 the Norton Motorcycle Company set up a development department at Thruxton circuit to support two racing Norton Commandos to represent the company in the Isle of Man TT races and the Thruxton 500. The Nortons achieved success over five seasons, during which time several improvements and modifications were developed.
