Swinging Arm
A swingarm ( or swinging arm), originally known as a swing fork or pivoted fork, is a single or double sided mechanical device which attaches the rear wheel of a motorcycle to its body, allowing it to pivot vertically. The main component of the rear suspension of most modern motorbikes and ATVs, it holds the rear axle firmly, while pivoting to absorb bumps and suspension loads induced by the rider, acceleration, and braking. Originally motorcycles had no rear suspension, as their frames were little more than stronger versions of the classic diamond frame of a bicycle. Many types of suspension were tried, including Indian's leaf spring suspended swingarm, and Matchless's cantilevered coiled-spring swingarm. Immediately before and after World War II, the plunger suspension, in which the axle moved up and down two vertical posts, became commonplace. In the latter, the movement in each direction was against coiled springs. Some manufacturers, such as Greeves, used swinga ...

Wheelie
A wheelie, or wheelstand, is a vehicle maneuver in vehicle acrobatics in which the front wheel or wheels come off the ground due to sufficient torque being applied to the rear wheel or wheels, or rider motion relative to the vehicle. Wheelies are usually associated with bicycles and motorcycles, but can be done with other vehicles such as cars, especially in drag racing and tractor pulling. History The first wheelie was reportedly performed by trick bicyclist Daniel J. Canary in 1890, shortly after modern bicycles became popular. Writing in 2009, Mike Seate related to the U.S. Army motorized cavalry training in 1943, pictured in Life magazine. Seate described "vaulting trenches and beach obstacles" and interpreted this technique as "High speed wheelies, naturally". Daredevil Evel Knievel performed motorcycle acrobatics including wheelies in his shows. Doug "The Wheelie King" Domokos has accomplished such feats as a wheelie. Types Types of wheelie can be divided into two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Motorcycle Drag Racing
Motorcycle drag racing (also known as "sprints") involves two participants lining up at a dragstrip with a signaled starting line. Upon the starting signal, the riders accelerate down a or long, two lane, straight paved track where their elapsed time and terminal speed are recorded. The rider to reach the finish line first is the winner. The best-known form of motorcycle drag racing is the Pro Stock Bike category, although several other categories exist, including Top Fuel and Pro Street. Motorcycles in the Top Fuel category are fueled by nitro methane and can make nearly 1,500 horsepower. From a standing start they can cover the first 60 feet in less than a second and can reach 200 mph in less than eighth-mile or 660 feet. The current world record is held by Top Fuel Veteran Larry "Spiderman" McBride who covered the quarter-mile in 5.50 seconds at 264 MPH on 21 November 2019 recorded at South Georgia Motorsports Park. Elmer Trett is considered by many to be the greatest mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Moto Guzzi
Moto Guzzi () is an Italian motorcycle manufacturer and the oldest European manufacturer in continuous motorcycle production. Established in 1921 in Mandello del Lario, Italy, the company is noted for its historic role in Italy's motorcycling manufacture, its prominence worldwide in motorcycle racing, and industry innovations—including the first motorcycle centre stand, wind tunnel and eight-cylinder engine. Since 2004, Moto Guzzi has been an ''unico azionista'', a wholly owned subsidiary, and one of seven brands owned by Piaggio Group, Europe's largest motorcycle manufacturer and the world's fourth largest motorcycle manufacturer by unit sales. The company's motorcycles are noted for their air-cooled 90° V-twin engines with a longitudinal crankshaft orientation where the engines' transverse cylinder heads project prominently on either side of the motorcycle. History Similar to other storied motorcycle manufacturers that have survived for decades, Moto Guzzi has experien ...

Shaft Effect
The shaft effect, also known as elevator effect or shaft jacking, is a phenomenon occurring in shaft-drive motorcycles. This effect occurs because the acceleration being applied to the rear wheel creates a reactive force on the drive shaft. This in turn lifts the rider and the body of the bike, exacerbating the natural "tucking under" of the rear wheel. Under acceleration Newton's third law says trying to turn the wheel forward exerts a reactionary force against the drive mechanism. In the case of a belt, this makes the top part of the belt tighten and the whole bike "shrug" down just a bit. This is typically obscured because acceleration causes the rear wheel to "tuck under." A shaft-drive, on the other hand has a rigid connection to the hub so this reactionary force turns the shaft backwards about the rear wheel and the middle of the bike "tightens" and lifts the rider up. This effect is one of the most notable differences between riding a shaft-driven motorcycle and a typical mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bicycle Suspension
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more than 1 billion bicycles. There are many more bicycles than cars. Bicycles are the principal means of transport in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys. Bicycles are used for fitness, military and police applications, courier services, bicycle racing, and artistic cycling. The basic shape and configuration of a typical upright or "safety" bicycle, has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern materials and computer-aided design. These have allow ...

Softail
A softail (shortened form of ''soft tail'') motorcycle intentionally looks like vintage motorcycles with a rigid hard-tail frame that has a triangle of steel tubes at the rear axle, as on a bicycle frame, but on a Softail these tubes are actually a triangular swingarm, with the shock absorber(s) hidden, as opposed to clearly visible regular twin shocks on both sides of the rear wheel on standard bikes. Since the introduction of the Harley-Davidson ''FXST Softail'' in 1983 as a registered trademark of the Motor Company, ''softail'' has become a genericized trademark for other models of cruiser motorcycles with rear suspensions hidden for retro style reasons. This was done even though the rear wheel was often hidden behind bags or exhaust pipes. History The first rear suspensions on motorcycles were introduced before World War I, and many companies offered fully suspended motorbikes before World War II, but most designs were either expensive, prone to wear and tear, or adde ...
