1949 Isle Of Man TT
The 1949 Isle of Man Tourist Trophy was the first round of the Grand Prix World Championship that was held in the Isle of Man. At the FICM (later known as ''FIM'') meeting in London near the end of 1948, it was decided there would be a motorcycle World Championship along Grand Prix lines. It would be a six-race annual series with points being awarded for a placing and a point for the fastest lap of each race. There would be five classes: 500 cc, 350 cc, 250 cc, 125 cc and 600 cc sidecar. The historic Isle of Man TT would be one of those races, and this toughest and most dangerous of Grand Prix motorcycle races would be a mainstay on the GP calendar until 1976. Harold Daniell, on a Norton, won the 500 cc Senior TT event at an average speed of 86.93 mph. Les Graham, on an AJS Porcupine 500 cc twin, led the Senior race until the last lap when his magneto drive sheared. He pushed the bike past the finish line in tenth place. As he had ...

11th Milestone
__NOTOC__ The 11th Milestone, Isle of Man (''Drinkwater's Bend'') is situated adjacent to the 13th Milestone on the primary A3 Castletown to Ramsey Road which forms the boundary between the parishes of Kirk German and Kirk Michael in the Isle of Man. History The area is dominated by the Ballamenagh and Shoughlaige-e-Caine farmland. During the 1830s, the primary A3 Road Castletown to Ramsey was re-profiled between and Handley's Corner by the local parochial highway surveyor under the former Isle of Man parish board system. This was to avoid marshland and steep inclines creating the distinctive elongated S-bend. The original stone 11th milestone on the A3 road was sited at the corner café at Glen Helen. An iron milestone from the 1860s during the period of James Garrow as Isle of Man Surveyor-General is now situated at the northerly end of the former 'Drinkwater's Bend' as the 13th Milestone on the primary A3 Castletown to Ramsey Road. The current site of the 11th marker p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior TT
The Junior TT is a motorcycle road race that takes place during the Isle of Man TT festival; an annual event at the end of May and beginning of June. Between 1949 and 1976 this race was part of the Grand Prix motorcycle racing season. Engine capacity The 1911 Isle of Man TT was the first time the Junior TT race took place and was open to 300cc single-cylinder and 340cc twin cylinder motor-cycles and was contested over 5 laps of the new 37.5 mile Mountain Course. The first event on the new course was the Junior TT Race and was contested by 35 entrants. It was won by Percy J. Evans riding a Humber motor-cycle in 3 hours, 37 minutes and 7 seconds at an average speed of 41.45 mph.

Ben Drinkwater
Reuben Thomas "Ben" Drinkwater (13 February 1910 – 9 June 1949) born in Rochdale,''Isle of Man Examiner'' pp4 dated 17 June 1949 Lancashire, England, was a railway signalman and motorcycle racer who competed in the Isle of Man TT races and the Manx Grand Prix. After riding in the 1946 Manx Grand Prix, the first post-war event on the Snaefell Mountain Course, Ben Drinkwater returned to race in the 1947 Isle of Man TT, finishing in third place in the controversial 1947 250 cc Lightweight TT race won by Manliff Barrington.

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-twin Engine
A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, Jet Skis, all-terrain vehicles, tractors and ultralight aircraft. Various different crankshaft configurations have been used for straight-twin engines, with the most common being 360 degrees, 180 degrees and 270 degrees. Terminology The straight-twin layout is also referred to as "parallel-twin", "vertical-twin" and "inline-twin". Some of these terms originally had specific meanings relating to the crankshaft angle or engine orientation, however they are often also used interchangeably. In the United Kingdom, the term "parallel-twin" is traditionally used for engines with a crankshaft angle of 360 degrees, since the two pistons are in the same direction (i.e. parallel to each ...

AJS Porcupine
The AJS 500 cc Porcupine was a British racing motorcycle built by Associated Motor Cycles (AMC), which débuted in 1945 with a horizontal-engine designated E90S. The later E95 model was developed with an inclined-engine. AMC produced AJS and Matchless brands at the time. Racing history The motorcycle was originally designed by AJS to be supercharged, as were a number of pre-war racing bikes, but the FICM banned supercharging in 1946. The motor was then worked on to allow it to perform without a supercharger. Jock West first rode the machine at the 1947 Isle of Man TT where he experienced teething problems relegating him to a 15th place, although he recorded the third fastest lap time of the race. Leslie Graham then rode the bike to victory in the inaugural 1949 FIM 500cc world championship. This was the only World Championship win for AJS. Despite this victory, the bike is often cited as unreliable, and not living up to its promise. Mechanicals Engine The E90S Porcupi ...

Leslie Graham
Robert Leslie Graham (14 September 1911 – 12 June 1953) was a British motorcycle road racer who competed in the 1930s and 1940s. He won the inaugural Grand Prix motorcycle racing 500 cc World Championship in 1949. Early Career (1929–1939) Les Graham started racing at Liverpool's Stanley Speedway on dirt. In 1929 he entered a race on the Oswestry Park Hall circuit, riding a second hand Dot-JAP, and came second to Henry Pinnington on an AJS. For the next few years he raced a succession of Rudge hybrids with varying success. In 1936 he managed to purchase a near new 250 cc OHC OK-Supreme cheaply, because it had dropped a valve. He rebuilt it, and entered it in the 1936 Ulster Grand Prix. After completing a lap of the Clady Circuit, the big end seized. He rebuilt it for 1937, and entered Northern Ireland's North West 200, and lead the Lightweights for a while until he came off. He remounted, joined the field, and was running third behind a couple of Excelsiors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senior TT
The Senior Tourist Trophy is a motorcycle road race that takes place during the Isle of Man TT festival, an annual event traditionally held over the last week in May and the first week in June. The Senior TT is the Blue Riband event of the festival that takes place on the Friday of race week, with "The Marquis de Mouzilly St. Mars trophy" awarded to the winner. The event was part of the FIM Motorcycle Grand Prix World Championship from 1949 to 1976, before being transferred to the United Kingdom after safety concerns, becoming the British Grand Prix under the FIM from the 1977 GP season. Until 2012, the Senior TT had never been cancelled except during the two World Wars and during travel restrictions associated with the animal foot and mouth outbreak in 2001. However, during the 2012 TT Races, with inclement weather on the day prior to its traditional Friday race day (8 June), the decision was taken to postpone racing until the following day, Saturday, 9 June.

Sidecar
A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle, making the whole a three-wheeled vehicle. A motorcycle with a sidecar is sometimes called a ''combination'', an ''outfit'', a ''rig'' or a ''hack''. History Jean Bertoux, a French army officer, secured a prize offered by a French newspaper in 1893 for the best method of carrying a passenger on a bicycle. The sidecar wheel was mounted on the same lateral plane as the bicycle's rear and was supported by a triangulation of tubes from the bicycle. A sprung seat with back rest was mounted above the cross-member and a footboard hung below. A sidecar appeared in a cartoon by George Moore in the January 7, 1903, issue of the British newspaper ''Motor Cycling''. Three weeks later, a provisional patent was granted to Mr. W. J. Graham of Graham Brothers, Enfield, Middlesex. He partnered with Jonathan A. Kahn to begin production. One of Britain's oldest sidecar manufacturers, Watsonian, was foun ...

Cubic Centimetre
A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of one millilitre. The mass of one cubic centimetre of water at 3.98 °C (the temperature at which it attains its maximum density) is almost equal to one gram. In internal combustion engines, "cc" refers to the total volume of its engine displacement in cubic centimetres. The displacement can be calculated using the formula :d = \times b^2 \times s \times n where is engine displacement, is the bore of the cylinders, is length of the stroke and is the number of cylinders. Conversions *1 millilitre = 1 cm3 *1 litre = 1000 cm3 *1 cubic inch = .
