1951 - Triumph Tiger T100
1951 - Triumph Tiger T100 - The Triumph works was destroyed by German bombers on the night of 14 November 1940. Post War, when Triumph recovered and began production again at Meriden the Tiger 100 re-appeared with the new telescopic fork. In 1951 it gained a new close finned alloy cylinder barrel and factory race kits for independent racers. In 1953 a fully race-kitted model, the Tiger 100C, was available although only 560 were made. 1954 saw the first swinging-arm rear suspension models and the Tiger 100 was developed year on year alongside the other models in the range. 1959 was the last of the pre-units (separate engine/gearbox) and in 1960 it was completely redesigned in the new 'unit' style as the T100A. A long line of T100SS, T100C, T100R and others appeared during the sixties in the UK and export (mainly US) markets culminating in the Daytona variants which soldiered on until 1973. The historic Tiger name was revived by the new Hinckley Triumph company in 1993. https://en.wikipedia.org/wiki/Triumph_Tiger_100
Triumph Bonneville T120
The original Triumph Bonneville was a 650 cc parallel-twin motorcycle manufactured by Triumph Engineering and later by Norton Villiers Triumph between 1959 and 1974. It was based on the company's Triumph Tiger T110 and was fitted with the Tiger's optional twin 1 3/16 in Amal monobloc carburettors as standard, along with that model's high-performance inlet camshaft. Initially it was produced with a pre-unit construction engine which enabled the bike to achieve 115 mph without further modification, but later in 1963 a unit construction model was introduced which was stiffer and more compact, including additional bracing at the steering head and swing arm. The steering angle was altered and improved forks were fitted a couple of years later, which, together with the increased stiffness enabled overall performance to match that of the Bonneville's rivals. Later T120 Bonnevilles used a new frame which contained the engine oil instead of using a separate tank; this became known as the oil in frame version. The T120 engine, both in standard configuration and especially when tuned for increased performance, was popular in café racers such as Tribsas (BSA frame) and particularly Tritons (Norton featherbed frame).
Vincent Series C Black Shadow Motorcycle
he 1948 Vincent Black Shadow was at the time the world's fastest production motorcycle at 125mph. The Black Shadow, capable of 125 mph (201 km/h), and easily recognised by the black coating on the engine and gearbox unit known as Pylumin, and large 150 mph (240 km/h) speedometer, was introduced. The engine produced 54 bhp (40 kW) @ 5700 rpm in Black Shadow trim. The Black Lightning was a racing version of the Black Shadow; every necessary steel part on it that could be was remade in aluminium, and anything not essential was removed altogether. These changes helped reduce the weight from 458 lb (208 kg) to 380 lb (170 kg). Every bit the racer,[opinion] it had a single racing seat and rear-set footrests. The name was changed to Vincent Engineers (Stevenage) Ltd. in 1952 after financial losses were experienced when releasing capital to produce a Vincent-engined prototype Indian (Vindian) for the US market during 1949. In 1955 the company discontinued motorcycle production after experiencing further heavy financial losses.
The Velocette Venom was a 499 cc single-cylinder four-stroke British motorcycle made by Velocette at Hall Green in Birmingham. A total of 5,721 machines were produced between 1955 and 1970. In 1961 a factory-prepared faired Velocette Venom and a team of riders set the 24-hour world record at a speed of 100.05 mph (161.01 km/h) at the Autodrome de Linas-Montlhéry, a banked oval racetrack in France. It was the first motorcycle to average over 100 mph continuously for 24 hours and no 500cc or single-cylinder motorcycle has broken this record. In 1965, the Velocette Venom was further developed with a full racing kit to create the range-topping Velocette Thruxton, with a special cylinder head developed by American flat-track racers, and adapted by Velocette to create a new production racer. It was a very popular and successful clubman racer, winning the 1967 Isle of Man Production TT. The Thruxton became the most popular Velocette model, but could not save the Velocette company from bankruptcy in 1971. Poor trading conditions over a number of preceding years forced the company into voluntarily liquidation in 1971, with all the remaining stock and tools sold off to pay creditors.
