is not traction control but a unique system onto itself. These later models allow for extensive customization of the ECU using Kawasaki's optional software system, as well as including a Digital Fuel Injection (DFI) coupler system. DFI couplers allow for immediate trackside changes to the ECU through the simple change of a plug-and-play module. Kawasaki provides three modules with new bikes, a Green (standard mapping), White (soft track conditions mapping) and Black (hard track conditions mapping). Fourth Generation 2016-2018 The 2016 KX450F is a new redesign from 2015, including significant changes to the engine, chassis and throttle body. Fifth Generation 2019-Present In 2019, Kawasaki dropped the F from the name. The 2019 KX450 is an all-new design, which includes electric start and eliminates the kick starter. The fork was switched from an air fork to a coil-based Showa fork, leveraging A-Kit technology.
