Bridgestone (motorcycle)
Bridgestone motorcycles were a division of the Bridgestone Tire Co. of Kyōbashi, Tokyo, Japan that produced mopeds and motorcycles from 1952 to 1970. Initially producing power assisted bicycles, the division moved on to producing mopeds and then motorcycles. The motorcycles were technologically advanced and powered by two-stroke engines. The high technical specification resulted in the machines being more expensive compared to other manufacturers models. Production was stopped in 1970 to protect the supply of tyres to other manufacturers. History In 1946 the tyre manufacturer Bridgestone started to produce bicycles and in 1949 the Bridgestone Cycle Company was formed. In 1950 an agreement was formed with ''Fuji Seimitsu Jogyo'' (Fuji Precision Engineering Company - now part of Nissan) to supply auxiliary engines for these bicycles. Initially the engines were supplied separately but from 1952 Bridgestone produced a bicycle fitted with the engine, the ''BS21 Bambi''. The 26 cc eng ...

Kyōbashi, Tokyo
is a neighborhood east of Tokyo Station in Chūō, Tokyo, Japan. It is one of the city's oldest commercial districts, although it has since been eclipsed by Ginza to the south and Nihonbashi to the north. Kyobashi, together with Nihonbashi and Kanda, is the core of Shitamachi, the original downtown center of Edo-Tokyo, before the rise of newer secondary centers such as Shinjuku and Shibuya. History Its name comes from the bridge that once spanned the Kyōbashi Canal. The south side of the canal was called Takegashi（竹河岸 Bamboo Quay）because it was bamboo wholesalers' area. The Kyōbashi, or Capital Bridge, linked the Ginza and the Kyōbashi neighborhood. According to the sign erected at the site by the Chuo-ku Board of Education, together with Nihonbashi, it was one of the famous bridges of Edo. When the canal was filled in 1959, the bridge was removed. Today, a pillar stands to mark the site of the old bridge. Kyobashi was also a ward of Tokyo City, encompassing 1 ...

Triumph Bonneville
The Triumph Bonneville is a standard motorcycle featuring a parallel-twin four-stroke engine and manufactured in three generations over three separate production runs. The first two generations, by the defunct Triumph Engineering in Meriden, West Midlands, England, were 1959–1983 and 1985–1988. The third series, by Triumph Motorcycles in Hinckley, Leicestershire, began in 2001 and continues to the present as a completely new design that strongly resembles the original series. The name Bonneville derives from the famous Bonneville Salt Flats, Utah, USA where Triumph and others attempted to break the motorcycle speed records. Development history T120 Bonneville 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 ...

Gaiter (vehicle)
{{Unreferenced, date=June 2019, bot=noref (GreenC bot) On a vehicle, a gaiter or boot refers to a protective flexible sleeve covering a moving part, intended to keep the part clean. On motorcycles and bicycles Gaiters are pleated rubber tubes enclosing the front suspension tubes of some motorcycles and mountain bikes with telescopic front forks. Gaiters protect the sliding parts of the front suspension from dirt and water. On cars and other vehicles Similar gaiters to those described above find multiple uses on most vehicles. They are used at both ends of driveshafts, protecting constant-velocity joints from the ingress of dirt, and retaining the grease. They also prevent the ingress of dirt where one component slides within another, for example, on suspension struts or the ends of steering racks. Finally, they are also usually used to perform the same function on ball joints, which appear on suspension wishbones and steering tie rod ends. The gear stick A gear stick (rarely ...

Carburettor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English a ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

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 o ...

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or Scavenging (automotive), scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scotland, Scottish engineer Dugald Clerk, who pa ...

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Tokyo Motor Show
The is a biennial auto show held in October–November at the Tokyo Big Sight, Tokyo, Japan for cars, motorcycles and commercial vehicles. Hosted by the Japan Automobile Manufacturers Association (JAMA), it is a recognized international show by the Organisation Internationale des Constructeurs d'Automobiles, and normally sees more concept cars than actual production car introductions which is the reason why the auto press see the show as one of the motorshow's big five (along with Detroit, Geneva, Frankfurt and Paris). For the first time in its 67-year history, the Tokyo Motor Show was cancelled for 2021 due to rising cases of COVID-19. History The show, originally called All Japan Motor Show was first held in an outdoor venue called Hibiya Park, the show was considered a success with 547,000 visitors over ten days and 254 exhibitors displaying 267 vehicles, but of the 267, only 17 of them were passenger cars as the show was dominated by commercial vehicles. In 1958, due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cafe Racer
A coffeehouse, coffee shop, or café is an establishment that primarily serves coffee of various types, notably espresso, latte, and cappuccino. Some coffeehouses may serve cold drinks, such as iced coffee and iced tea, as well as other non-caffeinated beverages. In continental Europe, cafés serve alcoholic drinks. A coffeehouse may also serve food, such as light snacks, sandwiches, muffins, fruit, or Pastry, pastries. Coffeehouses range from owner-operated small businesses to large multinational corporations. Some coffeehouse chains operate on a Franchising, franchise business model, with numerous branches across various countries around the world. While ''café'' may refer to a coffeehouse, the term "café" generally refers to a diner, British café (colloquially called a "caff"), "greasy spoon" (a small and inexpensive restaurant), transport café, teahouse or tea room, or other casual eating and drinking place. A coffeehouse may share some of the same characteristics of a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescopic Fork
A telescopic fork is a form of motorcycle front suspension whose use is so common that it is virtually universal. The telescopic fork uses fork tubes and sliders which contain the springs and dampers. The main advantages of the telescopic fork are that (i) it is simple in design and relatively cheap to manufacture and assemble; (ii) it is lighter than older designs using external components and linkage systems; and (iii) it has a clean and simple appearance that bikers find attractive. Telescopic forks sometimes have gaiters to protect the fork tubes from abrasion and corrosion. A more modern (and more expensive) version of the conventional telescopic fork is the inverted or "USD" (upside-down) fork. BMW's patented telelever front suspension appears at first glance to be conventional telescopic fork, but the fork tubes contain neither springs nor damping. Instead, a wishbone and an inboard monoshock perform suspension duties, and the forks serve to locate the front wheel an ...
