The Kawasaki Ninja ZX-14 (ZZR1400 in some markets, ZX-14R since 2012), is a motorcycle in the Ninja sport bike series from the Japanese manufacturer Kawasaki that was their most powerful sport bike as of 2007. It was introduced at the 2005 Tokyo Motor Show and released for the 2006 model year as a replacement for the ZX-12R. The ZZR1400 is capable of accelerating from 0–60 mph in 2.5 seconds. The top speed is electronically limited to 186 mph (299 km/h) as a result of an agreement between the major Japanese and European motorcycle manufacturers. The motorcycle was in season 10 of Fifth Gear on October 30, 2006. Motorcycle USA road tested the bike in its October 10, 2006 issue and posted the following stock results:

2008 saw a minor update. The launch of the 2012 ZX-14R saw a second-generation revision along with getting the R designation. A displacement increase which produced more horsepower, along with three variable power modes and KTRC. Kawasaki traction control and ignition-management system that was lifted from the ZX-10R. Also with cosmetic updates and incremental chassis upgrades and suspension revised internals. There was also a slipper clutch added for the first time. The motor gets cylinder heads with polished ports and cams with more lift and longer duration. Piston are lighter with added compression that get cooled by a new oil jet system. Stronger connecting rods and crankshaft as well as a stronger tensioner and cam chain. while the transmission gets heat treated surface gears. Also in an effort to make the motorcycle run cooler, and therefore be more durable, they added a second radiator fan. Larger head pipes and larger mufflers with a less restrictive air filter all improve response. Motor cyclist recorded Rickey Gadson’s quarter-mile time of 9.64 seconds at 149.83 mph from a bone-stock bike, on a 50-degree morning, at an altitude of 2100 feet. Cycle world recorded a quarter-mile time that produced a record 9.47-second (corrected) at 152.83 mph, and also hit 60 mph in just 2.6 sec.
