Roper Steam Velocipede
The Roper steam velocipede was a steam-powered velocipede built by inventor Sylvester H. Roper of Roxbury, Boston, Massachusetts, United States sometime from 1867–1869. It is one of three machines which have been called the first motorcycle, along with the Michaux-Perreaux steam velocipede, also dated 1867–1869, and the 1885 Daimler ''Reitwagen''. Historians disagree over whether the Roper or the Michaux-Perreaux came first. Though the ''Reitwagen'' came many years later than the two steam cycles, it is often labeled as the "first motorcycle" because there is doubt by some experts whether a steam cycle should meet the definition of a motorcycle. After his initial prototype of the late 1860s, Roper built a new and revised version in 1894, based on the then state of the art safety bicycle frame type. Sylvester Roper died of an apparent heart attack while riding this machine in 1896. An 1869 Roper machine is now in the Smithsonian Institution, and one from 1868 is in private h ...

Evel Knievel
Robert Craig "Evel" Knievel (; October 17, 1938 – November 30, 2007) was an American stunt performer and entertainer. Over the course of his career, he attempted more than 75 ramp-to-ramp motorcycle jumps. Knievel was inducted into the Motorcycle Hall of Fame in 1999. He died of pulmonary disease in Clearwater, Florida, in 2007, aged 69. Early life Knievel was born on October 17, 1938, in Butte, Montana, the first of two children of Robert E. and Ann Marie Keough Knievel. His surname is of German origin; his paternal great-great-grandparents emigrated to the United States from Germany. His mother was of Irish ancestry. Robert and Ann divorced in 1940, after the 1939 birth of their second child, Nicolas, known as Nic. Both parents decided to leave Butte. Knievel and his brother were raised in Butte by their paternal grandparents, Ignatius and Emma Knievel. At the age of eight, Knievel attended a Joie Chitwood auto daredevil show, which he credited for his later career cho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Museums In The United States
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] |

Honda CB77
The Honda CB77, or Super Hawk, is a straight-twin motorcycle produced from 1961 until 1967. It is remembered today as Honda's first sport bike. It is a landmark model in Honda's advances in Western motorcycle markets of the 1960s, noted for its speed and power as well as its reliability, and is regarded as one of the bikes that set the standard for modern motorcycles. Characteristics The CB77 had, at only 305 cc, a relatively big engine in comparison to most other Japanese bikes of the period, although it had performance to rival much larger motorcycles from other countries. It quickly built a reputation for reliability, and was equipped with luxuries such as an electric starter. The engine on the CB77 differed from that of the touring C77 version, in that the crankpins on the crankshaft were spaced 180 degrees apart. This had the benefit of making the engine smoother at higher revs but due to the firing sequence of one power stroke following another, the engine note sounde ...

Robert M
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Harley-Davidson Electra Glide Ultra Classic
The Harley-Davidson FL is a model designation used on Harley-Davidson motorcycles since 1941. The FL prefix is mostly applied to Harley-Davidson's large-framed bikes, including the current Touring series, and also the Softail series, especially those with traditional styling, 16-inch front wheels, and either Springer forks or large-diameter telescopic front forks. Early FL models The FL was introduced to the Harley-Davidson model line in 1941. It used a version of the " Knucklehead" OHV engine that powered the EL in form. The FL shared its frame with the EL and with the U and UL, which used a 74 cubic inch flathead engine. The FL replaced the UH and ULH, which used the same frame with flathead engines.Mitchell p. 95 The FL continued relatively unchanged until 1948, when it and the EL were given redesigned "Panhead" engines of the same capacities as before. These engines had several improvements over the earlier "Knuckleheads", including self-adjusting hydraulic li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Fairing
A motorcycle fairing is a shell placed over the frame of a motorcycle, especially racing motorcycles and sport bikes, to deflect wind and reduce air drag. The secondary functions are the protection of the rider from airborne hazards and wind-induced hypothermia and of the engine components in the case of an accident. A motorcycle windshield will usually be integrated into the design of the fairing.Tony Foale, ''Motorcycle Handling and Chassis Design'', , Chapter 5: "Aerodynamics" The major benefit of a fairing on sport touring and touring motorcycles is a reduction in aerodynamic drag, which allows for reduced fuel consumption and permits higher speeds at lower engine rpm, which in turn increases engine life. A motorcycle may have a front fairing, a rear fairing, a belly fairing, or any combination of these. Alternatively, a single fairing may partially or fully enclose the entire motorcycle, and may even enclose the rider. History The importance of streamlining was known ver ...

Harley-Davidson XR-750
The Harley-Davidson XR-750 is a racing motorcycle made by Harley-Davidson since 1970, primarily for dirt track racing, but also for road racing in the XRTT variant. The XR-750 was designed in response to a 1969 change in AMA Grand National Championship rules that leveled the playing field for makes other than Harley-Davidson, allowing Japanese and British motorcycles to outperform the previously dominant Harley-Davidson KR race bike. The XR-750 went on to win the most races in the history of American Motorcyclist Association (AMA) racing. The XR-750 is associated with the careers of racers Mark Brelsford, Cal Rayborn, and Jay Springsteen, and was the favorite motorcycle of stunt performer Evel Knievel. Knievel used the bike from December 1970 until his final jump in January 1977. An XR-750 was included in the 1998 '' The Art of the Motorcycle'' exhibition, and one of Knievel's bikes is in the Smithsonian's National Museum of American History ''America on the Move'' exhibit. * * ...
