Engine & Performance

A 1099 cm³ in-line four anchors the Ninja 1000SX, delivering 100.0 kW (134.1 hp) at 9,000 rpm and 113.0 Nm at 7,600 rpm. In practice, that means easy roll-on acceleration for highway passes and effortless overtakes without frantic downshifts. The in-line four’s smoothness is complemented by an 11.8:1 compression ratio and 38 mm fuel injection (x4), providing crisp response and predictable fueling in traffic or on twisty backroads.

A 6-speed, return-shift gearbox with ratios spanning from 2.600 in 1st to 1.069 in 6th works well for mixed riding—shorter lower gears help around town, while the taller top gear settles things down on long stretches. With a sealed chain final drive and a wet, multi-disc clutch, the drivetrain favors durability and a direct connection between throttle hand and rear tire.

Handling, Comfort & Kawasaki Ninja 1000SX Seat Height

Underneath, a twin-tube aluminium frame and 1,440 mm wheelbase strike a balance between stability and agility. A 98 mm trail and 31° left/right steering angles add useful low-speed maneuverability—handy for U-turns and parking lot shuffles. The Kawasaki Ninja 1000SX weight comes in at 235 kg (518.1 lbs), which places it firmly in sport-touring territory: planted on the highway, yet still manageable in city riding with smooth controls and predictable steering.

The Kawasaki Ninja 1000SX seat height is 835 mm (32.87 in), giving average-height riders a confident perch and room to stretch on longer rides. Shorter riders may appreciate the narrowish stance and the controllability afforded by the steering geometry. Suspension hardware is serious for the class: a 41 mm inverted fork with compression/rebound damping and spring preload adjustability up front, and a Horizontal Back-link, gas-charged shock with rebound damping and remote spring preload adjustability at the rear. Wheel travel is 120 mm front and 141 mm rear, enough to iron out rough pavement while keeping feedback clear during spirited riding. Tire sizes—120/70 ZR17 front and 190/50 ZR17 rear—support confident cornering and strong braking grip.

Ground clearance is 135 mm, and overall dimensions are 2100 x 805 x 1190 mm (1225 mm with the screen in its high position), providing a comfortable cockpit without feeling bulky.

Equipment & Features

Braking is handled by dual semi-floating 300 mm front discs with radial-mount, monobloc, opposed 4-piston calipers and a 260 mm rear disc with a single-piston caliper—serious stopping power with excellent feel. The ignition is digital, and starting is electric for everyday convenience.

Fuel capacity is 19.0 litres, and the stated fuel consumption of 5.6 l/100km (1.48 gal/100mi) supports long legs between stops. Additional chassis details include a sealed chain final drive and a twin-tube aluminium frame for stiffness and stability. The bike rolls on ZR17 rubber sized for sport-touring grip and longevity, and the adjustable suspension at both ends lets riders tailor the ride for solo commuting or weekend luggage.

Who Is the 2025 Kawasaki Ninja 1000SX For?

This machine suits experienced riders seeking a fast, smooth sport-tourer that can commute during the week and devour backroads on the weekend. The power and Kawasaki Ninja 1000SX weight make it less ideal as a very first motorcycle, but intermediate and advanced riders will appreciate its refined engine, stable chassis, and comfort. If you prioritize a four-cylinder’s top-end pull with real-world comfort and range, it’s squarely in your wheelhouse.

Torquepedia Verdict

The 2025 Ninja 1000SX stands out with its strong midrange torque (113.0 Nm), smooth 134.1 hp top end, and a chassis that blends stability with confidence. Adjustable suspension, serious brakes, and 19.0 litres of fuel capacity make it ready for long-haul sport touring. Efficiency at 5.6 l/100km and a comfortable 835 mm seat height add to its everyday usability.

On the downside, 235 kg is felt at a walking pace, and shorter riders may want to test the fit. But if you value an inline-four’s refinement and want one bike to commute, carve, and tour, this Kawasaki Ninja 1000SX review lands on a clear conclusion: it’s a compelling, mature sport-touring pick.
