BMW HP4 Race
The BMW HP4 Race is a four-cylinder engine sport bike made by BMW Motorrad in 2017 in a limited-production run of 750 units. It is a non- street-legal, track-only version of the HP4 variant of the BMW S1000RR. Background Like the Honda RC213V-S and Ducati Superleggera, the HP4 Race does not qualify for any race series, and was made to display the manufacturer's technological prowess rather than for Homologation. BMW claims the HP4 Race produces at 14,500 rpm, due to the higher rev limit over the normal HP4, which BMW says makes at 13,900 rpm. Most of the HP4 Race's design elements and engine are from the S1000RR, with many components re-tuned for higher performance, and adding greater adjustability, including a rake of 24.5° that can be decreased by 0.5° or increased by 1.0°. It has an all-carbon fiber chassis that BMW says weights , and fairing makes extensive use of carbon fiber. It has a GP style 1-up, 2-3-4-5-6-down shifting pattern. Like the S1000RR, HP ...

Quickshifter
A quickshifter (or quick shifter) is a device that eliminates the need to use the clutch or throttle when shifting gears on a manual transmission. This can increase the safety and comfort of the vehicle and allow for faster gear shifting (usually shifting in less than 50 milliseconds) and is thus a popular performance enhancement for motorcycles. Working mechanism Almost all quickshifters work on the same basis, a sensor detects the gear shift action, a microcontroller (CPU) processes the data (and calculates the timing) and cuts off ignition momentarily, resulting in a reduction of the load at the transmission allowing the new gear to slip (and engage) into place. However the method of sensing and reducing the load can vary. Sensor Most gearshift sensors work by measuring the pressure change (push or pull) on the shift rod. However, some sensors use a strain gauge, which is more expensive but may be more reliable and free from false readings due to vibrations since it has no ...

Traction Control System
A traction control system (TCS), also known as ASR (from german: Antriebsschlupfregelung, lit=drive slippage regulation), is typically (but not necessarily) a secondary function of the electronic stability control (ESC) on production motor vehicles, designed to prevent loss of traction (i.e., wheelspin) of the driven road wheels. TCS is activated when throttle input and engine power and torque transfer are mismatched to the road surface conditions. The intervention consists of one or more of the following: *Brake force applied to one or more wheels *Reduction or suppression of spark sequence to one or more cylinders *Reduction of fuel supply to one or more cylinders *Closing the throttle, if the vehicle is fitted with drive by wire throttle *In turbocharged vehicles, a boost control solenoid is actuated to reduce boost and therefore engine power. Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylinder ...

Carbon Fiber Reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other additiv ...

Bicycle And Motorcycle Geometry
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a bike handles. Wheelbase Wheelbase is the ''horizontal'' distance between the centers (or the ground contact points) of the front and rear wheels. Wheelbase is a function of rear frame length, steering axis angle, and fork offset. It is similar to the term wheelbase used for automobiles and trains. Wheelbase has a major influence on the longitudinal stability of a bike, along with the height of the center of mass of the combined bike and rider. Short bikes are much more suitable for performing wheelies and stoppies. Steering axis angle The steering axis angle is called caster angle when measured from vertical axis or head angle when measured from horizontal axis. The steering axis is the axis about which the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homologation (motorsport)
In motorsports, homologation is the type approval process through which a vehicle, a race track, or a standardised part is required to go for certification to race in a given league or series. The process of testing and certification for conformance to technical standards is usually known as type approval in English-language jurisdictions. The regulations and rules that must be met are generally set by the series's sanctioning body. The word is derived from Greek , . When a car loses the homologation form, that is, it becomes a historic vehicle, it can no longer be part of a competition and can only be used in historic competitions. Requirements In racing series that are "production-based", meaning that the vehicles entered in the series are based on production vehicles for sale to the public, homologation not only requires compliance with a racing series's technical guidelines (for example engine displacement, chassis construction, suspension design and such), but often ...

Ducati 1299
The Ducati 1299 Panigale is a Ducati sport bike unveiled at the 2014 Milan Motorcycle Show and produced since 2015 as a successor to the 1199. The motorcycle is named after the small manufacturing town of Borgo Panigale. The 1299 wheelbase remains the same at 1437 mm. The base version retains front forks by Marzocchi and Sachs shock absorber; The S variant has new semi-active Öhlins Smart EC suspension that can be switched between different driving modes to match road conditions. The entire range is now equipped with new generation of electronics, including a new IMU, racing ABS and anti-wheelie. Switchable riding modes and traction controls, similar to the old version, have been ported over onto the new platform. Ducati Panigale R Due to World SuperBike engine displacement regulations, the engine in the R variant of 1299 Panigale retains the old 1,198 cc displacement, with the addition of a tungsten-balanced crankshaft, titanium valves and con-rods and two-ring ...

Honda RC213V
The Honda RC213V is a Japanese motorcycle developed for road racing by Honda Racing Corporation to compete in the MotoGP series from the 2012 season and onwards. Rules for 2012 allowed motorcycles up to in capacity, with a limit of 4 cylinders and a maximum 81mm cylinder bore. The model name designates the following: *RC= Honda's traditional racing prefix for 4-stroke bikes *213= third works bike of the 21st century *V= V engine A limited-production run of a hand-built, road-going version designated RC213V-S was introduced in 2015 as a MotoGP replica. Honda merchandised a Sports Kit upgrade package to allow owners to improve the specification for non-road use. History Compared to the RC212V, the most significant new design features of the RC213V were its 1000cc displacement and 90° cylinder angle. The widening of the angle from 75.5° to 90° made it possible to increase the displacement to 1000cc without raising the center of gravity. It also resulted in a perfect primary ba ...

Street-legal Vehicle
Street-legal, road-legal, or road-going, refers to a vehicle such as a car, motorcycle, or light truck that is equipped and licensed for use on public roads, being therefore Roadworthiness, roadworthy. This will require specific configurations of lighting, signal lights, and safety equipment. Some specialty vehicles that will not be operated on roads, therefore, do not need all the features of a street-legal vehicle; examples are a vehicle used only off-road (such as a sandrail) that is Trailer (vehicle), trailered to its off-road operating area, and a Auto racing, racing car that is used only on closed race tracks and therefore does not need all the features of a street-legal vehicle. As well as motor vehicles, the street-legal distinction applies in some jurisdictions to track bicycles that lack street-legal brakes and lights. Street-legality rules can even affect racing helmets, which possess visual fields too narrow for use on an open road without the risk of missing a fast-mov ...

Sport Bike
A sport bike (sports motorcycle, or sports bike) is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads. They are mainly designed for performance at the expense of comfort, fuel economy, and storage in comparison with other motorcycles. Sport bikes can be and are typically equipped with fairings and a windscreen to deflect wind from the rider to improve aerodynamics. Soichiro Honda wrote in the owner's manual of the 1959 Honda CB92 Benly Super Sport that, "Primarily, essentials of the motorcycle consists in the speed and the thrill," while ''Cycle World''s Kevin Cameron says that, "A sportbike is a motorcycle whose enjoyment consists mainly from its ability to perform on all types of paved highway – its cornering ability, its handling, its thrilling acceleration and braking power, even (dare I say it?) its speed." Motorcycles are versatile and may be put to many uses as the rider sees fit. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
