Kawasaki Ninja ZX-12R
The Kawasaki Ninja ZX-12R is a motorcycle in the Ninja sport bike series made by Kawasaki from 2000 through 2006. The 1,199 cc (73.2 cu in) inline-four engine produced 178 hp (133 kW) at low speed, and increased to 190 hp (140 kW) at high speed due to its ram-air intake, making it the most powerful production motorcycle up to 2006 and the release of the ZX-14. It was a contender to be the fastest production motorcycle, and played a role in bringing to a truce the escalating competition to build an ever-faster motorcycle. Its top speed was electronically limited to 186 mph (300 km/h), tying it with the Suzuki Hayabusa and Kawasaki Ninja ZX-14 as the fastest production motorcycle on the market, after the 303–312 km/h (188–194 mph) 1999 Hayabusa was replaced with a speed-limited version as part of a gentlemen's agreement between motorcycle manufacturers that lasted until the 298–311 km/h (185.4–193.24 mph) 2007 MV Agusta F4 R 312.
