Susuki HayabusaThe Suzuki Hayabusa (or GSX1300R) is known to be the world's fastest production motorcycle, with a top speed of 188 to 194 miles per hour (303 to 312 km/h). This bike is definitely not for everyone. The bike is powered by a 1,340cc in-line 4-cylinder fuel injected, DOHC liquid-cooled engine with 16-valves and Twin Swirl Combustion Chambers (TSCC), providing staggering power. The engine is mated to a six-speed transmission that features oil spray to the 4th, 5th, and 6th gears, reducing wear and mechanical noise.
