^ The 1971 Norton Dunstall was the first "production motorcycle" to achieve a quarter-mile time under 12 seconds in Cycle World ' s testing, according to that magazine at that time. Later, in 2012, Cycle World said the 1972 Kawasaki H2 Mach IV was the first such production bike. The Norton Dunstall began as a factory-produced Norton motorcycle ...
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 1 ⁄ 4 mile (0.40 km) or 1 ⁄ 8 mile (0.20 km) long, two lane, straight paved track where their elapsed time and terminal speed are recorded.
The race follows a short, straight course from a standing start over a measured distance, most commonly 1 ⁄ 4 mi (1,320 ft; 402 m), with a shorter, 1,000 ft (0.19 mi; 304.80 m) distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning ...
Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.
In their test of a 1971 Norton Dunstall 810, Cycle World measured the top speed at 201 km/h (125 mph), with a 0 to 60 mph time of 4.7 seconds and a standing 0 to 1 ⁄ 4 mile (0.00 to 0.40 km) time of 11.9 seconds at 173.62 km/h (107.88 mph). [1] This was the first bike ever in Cycle World ' s tests with quarter mile time under 12 seconds. [1]
Performance was on a par with the GPz1100, at around 11.2 seconds at 125 mph (201 km/h) for the quarter mile and 148 mph (238 km/h) flat out. One magazine even branded it the fastest bike they had ever tested, and Kawasaki ran some ads claiming it to be "The World's Fastest Production Turbo Charged Bike". [ 2 ]
Ms Ellis currently holds the title of world’s fastest woman on a conventional motorcycle, after she went from a standstill to 264.1 miles per hour (mph) in 2014.
In 1960, he set the NHRA record for the largest improvement in the elapsed time (e.t.) when he drove the quarter mile in 8.84 seconds to break the previous 9.40-second record. [6] Hill raced at open competitions and Top Fuel events from 1955 until he retired in 1966. After opening a motorcycle shop, he returned several years later to race ...
