The 2024 Kawasaki Z900 is a fiercely capable naked bike that blends everyday usability with inline-four charisma. If you want a smooth-revving engine, balanced chassis, and real-world comfort, this is a compelling option in the super-naked middleweight space. This Kawasaki Z900 review focuses on how the numbers translate into the ride.
At the heart of the 2024 Kawasaki Z900 specs is a 948 cm³, liquid-cooled inline-four with a DOHC, 16-valve head. Its 92.2 kW {125 PS} at 9,500 rpm and 98.6 N•m at 7,700 rpm define the bike’s personality: tractable torque down low, a strong midrange, and a classic inline-four rush on top. Bore and stroke measure 73.4 x 56.0 mm with an 11.8:1 compression ratio—figures that support responsive revs and a lively character without sacrificing durability.
Fueling comes via fuel injection with sub-throttles (36 mm x 4), paired to a digital ignition and electric start for crisp response and easy cold starts. The 6-speed, return-shift transmission and sealed chain final drive put the power to the ground cleanly, with a wet, multi-disc clutch for consistent engagement. Real-world economy is respectable, with a fuel consumption figure of 5.7 l/100km (41.27 mpg) and CO2 emissions listed at 132 g/km.
In city riding, the torque peak at 7,700 rpm helps you short-shift and surf the midrange. On the highway, the motor settles into an effortless lope with plenty in reserve for passes. Weekend canyon runs are where the Z900’s smooth, linear delivery really shines—easy to modulate, yet thrilling when you let it spin.
The trellis, high-tensile steel frame and 1,455 mm (57.28 in) wheelbase give the Z900 a planted feel at speed while keeping it agile in tighter sections. A 110 mm (4.33 in) trail and generous steering angle of 33° both left and right help with confidence during low-speed maneuvering and U-turns. Ground clearance is 145 mm (5.71 in), adequate for spirited street riding.
The Kawasaki Z900 seat height is 820 mm (32.28 in), a friendly midpoint that many riders will find manageable. Combined with the 212 kg (467.38 lbs) curb mass, it strikes a balance: stable on the move while still approachable in parking-lot scenarios. Shorter riders benefit from the moderate perch, and taller riders should still have room to move.
Suspension travel is 120 mm up front and 140 mm at the rear—enough for comfort over broken pavement without sacrificing control. Tyres are sport-focused sizes: 120/70 ZR17 M/C (58W) front and 180/55 ZR17 M/C (73W) rear, delivering quick turn-in and confident drive out of corners.
Braking hardware is serious for a street naked: dual semi-floating petal discs up front (Ø300 mm) with opposed 4-piston calipers, and a single petal disc at the rear (Ø250 mm) with a single-piston caliper. The front suspension is an Ø41 mm inverted fork with rebound damping and spring preload adjustability, while the rear uses a Horizontal Back-link shock with rebound damping and spring preload adjustability. This level of adjustment lets riders tailor the ride to weight, pace, and road conditions.
Other notable items from the 2024 Kawasaki Z900 specs:
The Z900 best suits intermediate to experienced riders who want a lively inline-four with everyday comfort. It’s practical enough for commuting thanks to its smooth fueling and moderate seat height, yet exciting for weekend backroads. Newer riders with strong self-control may manage it, but the output and Kawasaki Z900 weight suggest it’s a better fit once you’ve built some seat time.
The 2024 Kawasaki Z900 delivers what enthusiasts love about inline-fours: a smooth, rev-happy engine with a rewarding top-end, matched to a stable yet nimble chassis. Adjustable suspension, strong brakes, and sensible ergonomics round out a package that works from Monday to Sunday.
On the flip side, the spec sheet focuses on fundamentals over flashy electronics, which some riders may prefer—and others may miss. Still, as a pure riding machine, the Z900 is a standout: approachable ergonomics, engaging performance, and a spec that punches above its weight in the naked class.
