BSA C15
The BSA C15 was a 250 cc single-cylinder ohv motorcycle manufactured by the British company BSA from September 1958 until 1967, and was BSA's first four-stroke unit-construction bike. For most of that period, after the introduction of 'Learner Laws' in 1961, a 250 cc was the largest capacity solo machine that a learner could ride unaccompanied when displaying L-plates in the United Kingdom. A road-going ''Sports'' derivative was added in 1961, and off-road versions, for Trials and Scrambles, were also available in the range. ''Motor Cycle'', 22 April 1965, pp.508-511 ''C15 Riders Report'' collated by ''Mike Evans''. Accessed 2014-10-18 Producing only , the C15's lack of power meant that it was hard for the BSA to compete with the more sophisticated Japanese motorcycles (such as the Honda C71 and CB72) which began arriving in the UK in the 1960s.

Triumph Tiger Cub
The Triumph Tiger Cub was a single-cylinder British motorcycle made by Triumph Motorcycles at their Meriden factory. Based on the ''Triumph T15 Terrier'' 150 cc, itself a surprise announcement just before the 1952 show, Motor Cycle, 30 July 1964. ''Readers report on Triumph Tiger Cub''. "''The Cub's ancestry dates back almost 12 years—to November 1952 when Triumphs introduced a "stimulating, last-minute eve-of-show surprise", the 149 cc Terrier. This was followed, a year later, by the first of the Tiger Cubs, with a 199 cc engine in the Terrier's plunger-sprung frame. Here we are dealing only with Cubs from 1957 onwards when the pivoted-fork model was introduced.''" Accessed 2014-01-29 the 200 cc T20 Tiger Cub was designed by Edward Turner, and launched at the Earls Court show in November 1953.

BSA Victor
The BSA B44 was a series of unit construction single-cylinder OHV four-stroke motorcycles made by the Birmingham Small Arms Company between 1966 and 1970. The machines were developed from the BSA World Championship Motocross machines, which were themselves based on the C15/ B40. Background In 1963 BSA began competing a C15T fitted with the 343 cc B40 engine in various disciplines. Works rider Jeff Smith won the Scottish Six Days 350 cc cup that year and finished 3rd in the 500 cc Motocross World Championship. Brian Martin, head of BSA's competition department, started a feasibility study to enlarge the B40 engine. The engine was enlarged to 421 cc, which was considered the maximum reliable size. For the 1964 Motocross season, the engine was fitted in a lightweight frame that carried the oil in the top tube. The machine weighed 228 lbs. Smith took this machine to 3 victories in the championship and, with 3 rounds to go, the displacement was increased to 441 cc. Smith won ...

Moto-Cross
Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. History Motocross first evolved in Britain from motorcycle trials competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. When organisers dispensed with delicate balancing and strict scoring of trials in favour of a race to become the fastest rider to the finish, the activity became known as "hare scrambles", said to have originated in the phrase, "a rare old scramble" describing one such early race. Though known as scrambles racing (or just scrambles) in the United Kingdom, the sport grew in popularity and the competitions became known internationally as "motocross racing", by combining the French word for motorcycle, ''motocyclette'', or ''moto'' for short, into a portmanteau with "cross country". The first known scramble race took place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Layshaft
A layshaft is an intermediate shaft within a gearbox that carries gears, but does not transfer the primary drive of the gearbox either in or out of the gearbox. Layshafts are best known through their use in car gearboxes, where they were a ubiquitous part of the rear-wheel drive layout. With the shift to front-wheel drive, the use of layshafts is now rarer. The ''driving shaft'' carries the input power into the gearbox. The ''driven shaft'' is the output shaft from the gearbox. In car gearboxes with layshafts, these two shafts emerge from opposite ends of the gearbox, which is convenient for RWD cars but may be a disadvantage for other layouts. For gearboxes in general, gear clusters mounted on a layshaft may either turn freely on a fixed shaft, or may be part of a shaft that then rotates in bearings. There may be multiple separate clusters on a shared shaft and these are allowed to turn freely relative to each other. Origins The term ''layshaft'' originates with watermill mac ...

BSA Barracuda
A barracuda is a large, predatory, ray-finned fish known for its fearsome appearance and ferocious behaviour. The barracuda is a saltwater fish of the genus ''Sphyraena'', the only genus in the family Sphyraenidae, which was named by Constantine Samuel Rafinesque in 1815. It is found in tropical and subtropical oceans worldwide ranging from the eastern border of the Atlantic Ocean to the Red Sea, on its western border the Caribbean Sea, and in tropical areas of the Pacific Ocean. Barracudas reside near the top of the water and near coral reefs and sea grasses. Barracudas are targeted by sport-fishing enthusiasts. Etymology The common name "barracuda" is derived from Spanish, with the original word being of possibly Cariban origin. Description Barracuda are snake-like in appearance, with prominent, sharp-edged, fang-like teeth, much like piranha, all of different sizes, set in sockets of their large jaws. They have large, pointed heads with an underbite in many species. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BSA B44 Shooting Star
The BSA B44 Shooting Star was a motorcycle made by Birmingham Small Arms Company, BSA at their factory in Small Heath, Birmingham, Small Heath, Birmingham. Similar to the BSA C15 and sharing many of the same parts, the B44 had an uprated chassis. A weak point of the BSA 250 and most 350 unit singles were the big end bearing and timing side crank bush. The B44 had a double roller big end and a single lipped roller bearing supporting the drive side of the crank, with a ball bearing on the timing side. The timing side ball bearing was prone to failure, so one popular update was to replace it with an NUP305 removable flange roller bearing, thus strengthening the timing side and controlling the crankshaft end float. On the B50 single lip roller bearings were fitted on both sides of the crankshaft, with an outrigger ball bearing on the drive side to provide increased rigidity and end float control. History In 1965 an off-road motocross BSA B44 named the ‘’Victor’’ was launched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
