In road racing, superchargers were not uncommon in the 1930s, and machines originally built for road racing also set many land speed records (see the list below for examples). Motorcycle racing in Europe went through a hiatus during the 1940s as World War II and its aftermath, and racing only restarted in 1946. [ 25 ]
The forward speed at which oscillations do not increase, where the weave mode eigenvalues switch from positive to negative in a Hopf bifurcation at about 5.3 m/s (12 mph) in this example, is called the weave speed. Below this speed, oscillations increase until the uncontrolled bike falls over. Above this speed, oscillations eventually die out.
Induction motors are most commonly run on single-phase or three-phase power, but two-phase motors exist; in theory, induction motors can have any number of phases. Many single-phase motors having two windings can be viewed as two-phase motors, since a capacitor is used to generate a second power phase 90° from the single-phase supply and feeds ...
The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...
MotoAmerica is the organization that promotes the AMA Superbike Series since 2015. Sanctioned by the American Motorcyclist Association (AMA) and the Fédération Internationale de Motocyclisme (FIM), it features eight classes of road racing: Superbike, Stock 1000, Supersport, King of the Baggers, Super Hooligan National Championship, Twins Cup, Junior Cup, and Mini Cup.
Otherwise, first electric vehicle to be considered for the position of the world's fastest street-legal production motorcycle, [37] [38] [39] to have won against ICE motorcycles in a professional road-based event and to have won any such race using only solar power. [40] Ducati Panigale R: 2013-2017 V-twin: 1,198 cc (73.1 cu in) 202 bhp (151 kW)
The Lambky Liner is a motorcycle land-speed record streamliner designed by Navy veteran and Vincent motorcycle restorer Max Lambky from Kansas, United States. [3] It reached a top recorded speed of 250 mph (400 km/h) at the 2007 International Motorcycle Speed Trials, [1] and an estimated 275 mph (443 km/h) in second gear before a supercharger spindle broke and spoiled a run in 2008.
A Suzuki GSX-R1000 at a drag strip – a 2006 model once recorded a 0 to 60 mph time of 2.35 seconds. This is a list of street legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1 ⁄ 4-mile times of under 12 seconds.
