Engine and performance
At the heart of both models is a 1,099 cc inline four-cylinder engine, already familiar from the Ninja 1100 and Versys 1100. The engine has been further developed for the Z1100 and, according to Kawasaki, delivers 100 kW (136 hp) at 9,000 rpm. The maximum torque is 113 Nm at 7,600 rpm. This puts the Z1100 below some of its competitors, such as the Honda CB1000 Hornet, in terms of performance, but it still offers sufficient reserves for sporty road riding. The engine overhaul includes new camshaft profiles, revised valve springs, modified pistons, and adjusted gear ratios, with the 5th and 6th gears in particular being lengthened.
Chassis, suspension, and weight
The aluminum twin-tube frame remains the distinctive backbone of the new Z1100, complemented by a new aluminum swing arm with a standard chain tensioner instead of an eccentric. The front suspension consists of 41 mm SFF-BP upside-down forks, while a horizontally mounted back-link shock absorber works at the rear. The Z1100 SE is additionally equipped with an Öhlins S46 shock absorber with remote preload adjuster. Kawasaki specifies the fully fueled weight as 221 kg (approx. 487 lbs) – identical to its predecessor and at the upper end of the scale compared to other supernaked bikes.
Brakes and tires
The standard version has monobloc brake calipers and 310 mm brake discs at the front. The SE version offers Brembo radial monobloc brakes with 310 mm Brembo discs, steel braided lines, and an Öhlins shock absorber at the rear. Both models roll off the production line on Dunlop Sportmax Q5A tires.
Ergonomics, design, and instrumentation
The handlebars have been widened by 22 mm and moved forward by 13 mm, which, according to Kawasaki, improves feedback and makes handling feel easier. Visually, the aggressive Sugomi design remains dominant – with striking LED headlights, a newly shaped skid plate and an eye-catching rear silencer. The SE variant is distinguished by gold fork legs and rims, as well as a unique color design. The seat height is 815 mm on both versions.
The cockpit is dominated by a 5-inch TFT color display with smartphone connectivity, turn-by-turn navigation, and the Kawasaki Rideology app, including voice control. A USB-C port is standard on the SE.
Electronic assistance systems
The Z1100 series is extensively equipped with electronics. These include electronic throttle valves (ETV), cruise control, Quickshifter (KQS) for upshifting and downshifting, a 6-axis IMU for lean-angle-dependent systems, KTRC traction control, KIBS integral brakes, selectable riding modes (Sport, Road, Rain, Rider/Manual), power modes, and KCMF cornering management.
Prices, variants, and availability
Both variants are expected to be available at dealers starting in October 2025. The standard version starts at €11,995 (approx. $12,650), while the Z1100 SE costs €13,795 (approx. $14,550). In the UK, prices are £11,099 (standard) and £12,699 (SE). The paint finishes vary depending on the model, with the SE being the more eye-catching of the two.
Conclusion: evolution instead of revolution
Kawasaki has deliberately opted for evolution with the new Z1100, consistently continuing the familiar line. With modernized engine and electronic features, a revised chassis, and additional equipment in the SE version, the model remains competitive, even if its performance figures lag behind some of its rivals. The Z1100 remains the flagship among Kawasaki’s large-displacement naked bikes and appeals above all to lovers of classic Z virtues.
