The newest member of the championship winning ZX line up is a 250cc beast, with a big bore attitude.
The only in-line four model in its class, the Ninja ZX-25R features an all new in-line four engine which delivers superior performance, eclipsing all other bikes in the 250cc to 300cc field.
Intense In-Line Four Engine
The Ninja ZX-25R is equipped with an all-new engine design – a 250cc, In-Line Four, Liquid Cooled engine – the only one in its class. This new engine delivers performance that eclipses other 250cc models in the field. Direct throttle response and a flexible character that combines strong low-mid range torque for city riding, and intense high-rpm power that can be enjoyed when track riding. High-spec ECU that uses the same base platform as the ZH2, and is loaded with Kawasaki’s latest electronics
Key chassis dimensions were inspired by Kawasaki’s World Superbike Ninja ZX-10RR racing bike. Designed using Kawasaki’s advanced dynamic rigidity analysis, the all-new lightweight trellis frame delivers the required balance of strength and chassis flex to achieve nimble super sport-style handling.
The Ninja ZX-25R also comes with an arched swing-arm design. This swing-arm design enables the short silencer to be positioned more centrally, contributing to better balance, and adding to its stylish, sporty looks.
Showa SFF-BP Front Fork
The Ninja ZX-25R’s 37mm inverted front fork uses a Showa SFF-BP (Separate Function Fork – Big Piston) front suspension. This offers riders the convenience of having separate adjustments to the damping and rebound (vs traditional suspension systems that combine both in both forks). This advanced fork offers both racetrack performance and everyday usability. The first ever time that this feature us used on the 250cc class.
Kawasaki Traction Control
The Ninja ZX-25R is the first 250cc model to feature traction control. Provides enhanced sport riding performance and peace of mind under certain riding conditions to prevent accidents on low-traction surfaces. Comes in three modes. Mode 1 is for near perfect road conditions, Mode 2 is for normal riding conditions, and Mode 3 is for highly slippery conditions. Modes 1 and 2 prioritize maximum acceleration, while Mode 3 prioritizes maximum stability.
