These were subsequently taken from the monastery by Godwin, Earl of Wessex, Earl Godwin for his fourth son, Tostig Godwinson, Tostig.

Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nodular Iron
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its ''nodular graphite'' inclusions. On October 25, 1949, Keith Dwight Millis, Albert Paul Gagnebin and Norman Boden Pilling received US patent 2,485,760 on a cast ferrous alloy for ductile iron production via magnesium treatment. Augustus F. Meehan was awarded a patent in January 1931 for inoculating iron with calcium silicide to produce ductile iron subsequently licensed as Meehanite, still produced . Metallurgy Ductile iron is not a single material but part of a group of materials which can be produced with a wide range of properties through control of their microstructure. The common defining characteristic of this group of materials ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The AJS 7R was a British 350 cc racing motorcycle built from 1948 to 1963 by Associated Motor Cycles. It was also commonly known as the ‘Boy Racer’, and won victories both for the factory and for privateers right from its introduction in 1948. The AJS 7R A new design by Phil Walker, the chain-driven overhead camshaft 7R had the history of the pre-war AJS ‘cammy’ singles behind it. Initially, the 7R was not quite as powerful as its competitors, producing at 7500 rpm. The duplex frame and Teledraulic front forks remained relatively unchanged during production, while the engine had a number of changes. The included valve angle was progressively narrowed, and the crankshaft strengthened. In 1956 the engine dimensions changed from the original long-stroke 74 x 81 mm to the ‘squarer’ 75.5 x 78 mm. The AMC gearbox replaced the older Burman unit in 1958. AJS 7R3 In 1951 AJS development engineer Ike Hatch developed a 75.5 mm bore x 78 mm stroke ...

Thruxton 500
The Thruxton 500 was a motorcycle endurance race for production based road machines, covering 500 miles and ridden by a team of two riders per machine. The first event was a 9-hour race which took place in 1955, organized by the Southampton and District Motorcycle Club (SDMCC) at the Thruxton Circuit near Andover in Hampshire. Two more 9-hour races followed in 1956 and 1957. These earlier 9-hour races resulted in the birth of the famous Thruxton 500 miler, the first taking place in 1958 and the last in 1973. The Thruxton 500 was an endurance race for production based road machines, covering 500 miles and ridden by a team of two riders per machine. There were twelve Thruxton 500 events between 1958 and 1973. During that period, there were four races where the 500 miler had to be run at two different circuits because of poor track conditions at Thruxton. The first rearranged 500 miler race was at Castle Combe in 1965 followed by three other meetings at Brands Hatch in 1966, 1967 a ...

Norton Atlas
The Norton Atlas was a Norton motorcycle made between 1962 and 1968, until it was replaced by the Norton Commando. Development The Mark 1 Atlas was launched as the 750SS in the early 1960s, but by the time it appeared c. 1962 it was being called a 750cc Atlas, with Norton's famous Featherbed frame. Designer Bert Hopwood’s 1949 497cc Dominator engine had been bored and stroked over the years to 745cc, via 600cc and then 650cc versions, to appeal to the American market and initially was only produced for export.

Norton P11
The Norton P11 is a air-cooled OHV parallel twin motorcycle that was made by Norton-Villiers from 1967 to 1969. Designed as an extremely light high power-to-weight ratio desert racer, P11 was revised in 1968 to the P11A and marketed as the Norton Ranger, a road legal version of the P11 with a more comfortable seat to make it suitable for normal road use. The Norton P11 gained a reputation as a ' desert racer' in the late 1960s but by 1969 lighter two stroke desert racers began to dominate the sport and the Norton had begun Commando production and it was selling well. Norton ended production of the P11 series to concentrate on the Commando, which used a number of ideas developed on the P11 series. Development Norton-Villiers developed the P11 from the Norton Atlas and Norton/Matchless N15CS and G15CS models as an export model for the growing sport of desert racing.
