Overview
The 2026 Kawasaki Ninja ZX 4R is a sportbike in production from 2023 to 2026. Its liquid-cooled, 399 cm³ in-line four produces 76 hp (57 kW) and 39 Nm of torque, with a wet weight of 189 kg.
The 39 Nm peak arrives at 13,000 rpm, putting the strongest pull high in the rev range. A 15 L tank and fuel consumption of 5.10 L/100 km work out to roughly 290 km per tank at that rate. The 800 mm seat and 189 kg wet weight shape its fit and low-speed maneuvering, while the adjustable Showa suspension lets riders tune preload at both ends and compression and rebound at the front.

Pros and cons
Advantages
ABS braking
ABS is fitted, helping prevent wheel lock under hard braking.
Adjustable suspension
Spring preload is adjustable at both ends, and the front fork also offers stepless compression and rebound damping.
Assist and Slipper clutch
The Assist and Slipper clutch can reduce rear-wheel hop during hard downshifts.
Things to consider
Chain final drive
The chain needs periodic cleaning and adjustment.
Limited ground clearance
The 135 mm ground clearance can make tall obstacles and rough roads more demanding.
High-revving torque peak
Peak torque arrives at 13,000 rpm, so the strongest pull comes high in the rev range.
