A softail 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.
Vincent Motorcycles was a British manufacturer of motorcycles from 1928 to 1955. The business was established by Philip Vincent who bought an existing manufacturing name HRD, initially renaming it as Vincent HRD, producing his own motorcycles as HRD did previously with engines purchased as complete assemblies from other companies. From 1934, two new engines were developed as single cylinder in 500 cc and v-twin 1,000 cc capacities. Production grew from 1936, with the most-famous models being developed from the original designs after the War period in the late 1940s.
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above 52 km/h (32 mph), however in recent years larger motors have been built, allowing bikes to reach speeds of upwards of 72 km/h.

The Yamaha WR450F is an off-road motorcycle made by Yamaha Motor Company. It currently has a 450 cc (27 cu in) liquid-cooled single-cylinder engine. First offered in 1998 at 400cc, it shared many components and design concepts with the YZ400F motocross model. It is basically the racing YZ450F detuned slightly for more controllable power, with a headlight and lighting coil, softer suspension, a kickstand, lower noise specifications, larger radiators and lower emissions. The WR in the name indicates a wide-ratio gear box common to most enduro or trail bikes and stands in contrast to the close-ratio gearbox essential to a motocross racer. Over the years the WR has benefited from the advances made in the YZ motocross version gaining displacement and advancements such as an aluminum frame and improved suspension. Over much of its life the weight of the WR450F has remained fairly constant ranging from 244 to 249 pounds dry weight.
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine.
A vehicle frame, also historically known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
Fuldamobil is the name of a series of small cars produced by Elektromaschinenbau Fulda GmbH of Fulda, Germany, and Nordwestdeutscher Fahrzeugbau (NWF) of Wilhelmshaven between 1950 and 1969. Various designated versions of the car were produced, although the vehicles produced under each designation were not always identical and the designations were sometimes misapplied. Though overall numbers produced were relatively small, the cars attracted sufficient attention to see licensed construction on four continents including Europe. In its ultimate configuration it is said to have inspired the term "bubble car". It is acknowledged as the first car in the world to feature a negative scrub radius, now recognised as a major advance in driving safety.
Ascot-Pullin Motorcycles was a British motorcycle manufacturer founded by Cyril Pullin as the Ascot Motor & Manufacturing Co Ltd. at Letchworth, Hertfordshire in 1928. An inventor and winner of the 1914 Isle of Man TT, Pullin had been developing ideas for motorcycle designs since 1920 with Stanley Groom, and had patented a two-stroke engine motorcycle with pressed sheet metal frame and forks. After leaving Douglas the first time, Pullin worked with Groom again to refine his ideas and develop and patent the Ascot-Pullin motorcycle. Fewer than 500 were built and sales were poor, resulting in the company's liquidation in 1930.
The Brough Superior Austin Four was a limited-production motorcycle designed and manufactured by Brough Superior of Nottingham, UK in 1932. It was listed in the 1932 Brough Superior catalogue as the 'Straight Four' but it was commonly known as the Brough Superior Austin Four, or BS4, or '3-wheeled Brough'. The machine is unique in its design, being powered by a modified Austin 7 automobile engine and gearbox unit, from which a driveshaft emerges on the centre-line of the motor. Rather than design a new gearbox, George Brough had the inspiration to keep the central driveshaft, and use a pair of close-couple rear wheels driven by a central final drive box. This 3-wheeled design was legally considered a motorcycle as the wheel centres were within 24". The Brough Superior-Austin Four created a sensation when revealed at the 1931 Olympia Motorcycle Show.
