Chris Vincent is a former motorcycle sidecarroad racer who was very successful in short-circuit racing in the 1960s and early 1970s. He entered Grands Prix using BSA, BMW and URS engines. He also rode solo motorcycles, particularly in the smaller race classes and production-machine categories.
Early days
Vincent left school at the age of fifteen and joined the BSA factory situated in Birmingham. In 1954 he joined the Norton race shop and started racing in speedway and on grass using a speedway machine with a JAP engine, later replaced by BSA engines. Whilst working for Norton, Vincent came into contact with established sidecar racer Cyril Smith and became interested in sidecars, later becoming grasstrack National Sidecar Champion in 1958.
Before becoming well known through road-racing in the 1960s, Vincent returned to work for BSA as a bike-tester based in the Birmingham area involving road testing for performance and economy including regular stints at the MIRAproving ground. After racing on grass-tracks and speedway, he graduated to tarmac courses in 1959 on a BSA. He raced a solo BSA Road Rocket in the Thruxton 500 mile endurance race partnered by Norman Storer finishing seventh, and again a BSA C15 in the 1961 Silverstone 1000 endurance event, partnered by Bert Morris, finishing with speedway and selling his outfit in 1961.
He first entered the Isle of ManSidecar TT race in 1960 followed by 1961, with DNFs in both events. He then won in 1962 with passenger Eric Bliss whom he first raced with for part of the 1961 season, establishing the first all-British Sidecar TT win since 1954, the first mountain circuit win by a British machine since 1925, and the first-ever international TT victory by a BSA. Vincent campaigned the early BSA A7 500 cc pre-unit construction engined sidecar outfits and then later the unit-construction A50 engines when these became available after 1962. During the 1960s some sidecar races particularly those carrying World Championship status including the TT were restricted to 500 cc, whereas the UK national series races had classes where 650 cc and larger engines were used. He is associated with popularising the true 'kneeler' concept, and although this was earlier attributed to Eric Oliver who used a semi-kneeler in the 1950s, Chris' own frame designs enabled a sidecar outfit with a much lower frontal area and smaller proportions hence better streamlining and lower centre of gravity which is fundamental for high-speed cornering. Vincent believed his road-racing success was in part due to his experiences on grass giving him an advantage over many of his rivals, stating "Where I have an advantage over many of my rivals is on corners. The power comes in much sooner and my grass track experience has taught me how to avoid and get out of trouble". carburettors and gearbox output coupling to shaft final drive Chris later used the only reliable, competitive engine for Grands Prix and UK 500cc events, the flat-twin BMW RS54 Rennsport During the middle 1960s, sidecar riders sought to achieve greater engine capacities and basic raw power. This included use of car engines and three-wheeled, car-type layouts driving a pair of front wheels. He started to develop a new concept with a repositioned Rennsport BMW engine. Instead of a shaft driving the rear wheel, it would drive the front and sidecar wheels. The outfit was soon 'outlawed' by the FIM, the European road-race regulatory body, as the front and rear wheels were designed to be out-of-line, hence deemed to be a three-wheeler, causing Vincent to revert to his 'old', conventional outfit. For the 1972 season Vincent used a Munch-URS engine based on a Helmut Fath design. He finished fourth in the Championship with a win at the Finnish Grand Prix held at Imatra. Before the start of the 1973 season, Munch backer American George Bell pulled the finance from the race team, putting the project up for sale, leaving Vincent without machinery. Vincent retired from competition in 1974 after campaigning a Yamaha-engined outfit, although he continues to ride in demonstration events.
Personal life
During the 1980s Chris had a motor cycle shop in Earl Shilton, Leicestershire where he still lives His sons Max and Jason were both established as solo motorcycle road-racers by the 1990 season. Jason 'Jay' Vincent was a successful racer at national, international and world level during the 1990s and continuing into the 2000s, scoring points in the British round of 2001 500cc GP at Donington Park on a Red Bull Yamaha when standing-in for injured Garry McCoy, having been released by his Pulse team for the event. He retired at the end of 2006 season Always a motor enthusiast, during the 1990s Chris had an American Vixen motorhome and owned Brough Superior vintage motorcycles.
