Kawasaki’s former Z1000 ran for a long time, beginning in 2004 and updated in 2014, before being split up by the Z900 and the insane Z H2, and this new 2026 Z1100 SE is meant to be a modernization of that famously raw original. As alluded to in its name, the major highlight is a larger-displacement engine to enable more torque and a broader powerband, and - in a major break with prior Kawasaki Z bikes - the implementation of modern electronic rider aids.
What’s new?
Externally, the Z1100 is almost identical to former and existing Z bikes, using the same vicious Sugomi styling meant to evoke a crouching predator, and it still looks fantastic. Keen eyes will note this SE model carrying Brembo M4.32 front brakes and an Ohlins S46 rear shock, adding a little bit of detail pop and a lot of streetfighter function.
Engine
This engine is a treat. It's based off the former 1,000cc engine, and the tweaks to it might sound disappointing at first: longer stroke, milder cams, narrower intakes, heavier flywheel. Peak power comes in at 136 horsepower at 9,000 rpm with a redline of 10,500, and 83 foot-pounds of torque at 7,600 rpm, but those factoids don’t tell the whole story. As a result of the tweaks to cam profiles and intake, mid-range power and roll-on response are much improved, and this enabled Kawasaki to fit slightly taller 5th and 6th gears to improve fuel efficiency - having that said, we observed an average of 7.2L/100km… which is indicative of how it wants to be ridden. I can't be held accountable for how ridiculously good the intake sounds.
To help take some of the edge off, it’s been fitted with a secondary balance shaft to smooth vibrations, and I can confirm it is indeed a slick engine. Perhaps more important than that, the new engine now has throttle-by-wire, and with that comes selectable ride modes (rain, road, sport, and 2 programmable rider modes), traction control, and a 2-way quickshifter.
Chassis and tech
Alongside the updated engine control, the chassis side of the Z gets modernized as well. One of the few amenities the Z already had was ABS, and it is now lean-sensitive. This is thanks to the IMU-Enchanced Chassis Orientated awareness system that accounts for longitudinal and lateral forces, as well as roll and pitch, all to enable the bike’s digital safety nets to work with greater precision and not get in the way of a good time.
A 5-inch TFT display serves as the gauge cluster and hub for the Z1100's new tech, with three standard ride modes, and a user-programmable mode. It's not the most intuitive to use, but it's familiar if you're used to Kawas, and it works well. It also integrates with Kawasaki's Rideology App, which adds turn-by-turn navigation functionality, among other niceties.
Mechanically, it uses the same horizontal rear shock setup and the same adjustable Showa 41mm inverted forks as before, enhanced on this SE by the aforementioned Ohlins rear damper. Braking is handled by 310mm semi-floating dual discs with 4-piston Brembo calipers. It weighs in at 487 pounds, ready to roll.
On the road
This may be modernized Z, but it still very much puts the fight in streetfighter. The riding position is snug; you’re positioned quite far forward, almost feeling like you’re straight over the steep forks, elbows out, legs tucked up close; it’s ergonomically closer to a full-fairing sport bike than most of the nakeds I've ridden.
Kawa’s tweaks to the way this engine delivers power have been quite successful; it very much likes to rev, but does not need to, with a strong mid-range roll-on that keeps building to its redline, with a gorgeously guttural intake shriek, and it feels far faster than its numbers convey. The new traction control and, more specifically, wheelie control are very helpful on this machine. I’ll borrow this comment from my WhatsApp chat with my colleague Erik:
It is V I O L E N T
That bike does NOT feel like 136 horsepower
It very much lives up to its crouching-tiger Sugomi styling, it is a furious machine; I would hesitate to call it demanding to ride fast, because it is ergonomically sound and well set up, but it’s not the friendliest thing out there. You have to work a bit to get it to lean over and have confidence to really push it, and it feels edgy with its sharp responses, but it never tried to bite me and my still-relatively-novice-ass either.
I could feel it had a lot more to give, and liked that it felt it was willing to help me get there, but not willing to do it for me. Once you learn to trust and push it, it’s easy to set up through a corner, easy enough to trim or widen a line, it isn't easily upset by uneven pavement, power rolls on predictably, and the brakes have great feel.
For all its Sugomi fury and brutal performance potential, it is an approachable bike that wouldn’t be a chore to live with. The clutch throw is easy to read (with a slight chattering sensation on take-off that may have been specific to this bike) and the engine has enough torque to make taking off a cinch at any speed.
You don’t need to rev it to the moon to get anywhere confidently, it runs smoothly, and the shifter and quickshifter mechanism are very impressive in how slick they work. It’s definitely firm over bumps, but not abusive. The added ride modes and traction control and ease of control means you could ride this all the time fairly easily.
Wrap it up
It’s great if you want a litre bike, but don’t want the problems that come with a litre bike - namely the cramped ergonomics and, perhaps more importantly, the completely inaccessible performance. This Z1100 SE is set up such that its performance can be utilized and toyed with, without having to delve into psychotic speeds. It will happily hang with the best of them, and scratch the itch for all but the most demonically-possessed of riders.
The 2026 Kawasaki Z1100 SE is a lot of bike for $18,599, with a lot of serious speed hardware, a silly amount of performance potential in a beautifully built, uniquely styled package. You could be cynical and say it’s a softened engine on an old platform, but you’d be missing the point; none of its newness detracts from the experience at all, and instead only adds to the magic by making it easier to have more fun, more of the time.
