Kawasaki Z900 Acceleration & Top Speed

The Kawasaki Z900 0-60 mph in 3.10 seconds

The Kawasaki Z900 is a midrange naked bike that competes in a very diverse and competitive class up against models such as the MT-09 ,790 Duke , CB1000R and even its sibling the Z900RS.

Below we have top speed and acceleration data through the gears, accompanied by Dyno Curve and Thrust Curve graphs.

Kawasaki Z900 Dyno Curve

The Z900 produces a claimed 125 horsepower at 9,500 rpm from its 948 cc inline-four engine.  Peak torque is a solid 72 ft-lb at just under 8,000 rpm.

These kinds of numbers are a little lower than those of an early-generation Kawasaki ZX-9R.

By today’s standards, these figures are not earth-shattering in a world full of 180–200 horsepower naked bikes.

At the rear wheel, the numbers look a little more modest, with 110 horsepower at 9,800 rpm and 69 ft-lb of torque at 8,000 rpm.

On the plus side, the power and torque are spread very nicely and delivered in a smooth, linear yet in an intense manner, much like the Z H2, with almost no peaks or troughs.

The engine pulls strongly from high gears and will even drive cleanly from tickover. 

We must remember what the Z900 is actually up against.

While it is tempting to compare it with machines such as the Yamaha MT-10, Ducati Streetfighter V4 and KTM 1290 Super Duke R, that would not be entirely fair

The Z900’s 110 horsepower at the rear wheel looks far more competitive when pitched against bikes like the Yamaha MT-09, KTM 790/890/990 Duke models, and even Triumph’s 765 Street Triple.

On the road, the engine is excellent and, like many naked bikes, feels like it has more power than it does.

Much of this is down to lower gear ratios and a good spread of torque.

The Z900 is very punchy and more so than many big superbikes that have 80 horsepower more.

For example, in top gear from 70-100 mph, the Z900 can run with a first-generation ZX-14R despite giving away a large amount of engine capacity, power, and torque.

This is because the Z900 is lighter and has lower gear ratios, which makes the best use of its available torque. The Z900 can do this as it does not need to be geared to hit 190 mph plus.

Kawasaki Z900  Acceleration through the gears

The Kawasaki Z900 is something of a dragster, putting its 110 rear-wheel horsepower to excellent use.

This level of power, combined with well-chosen gearing, creates a great balance: enough to lift the front wheel when you want it to, but not so much that it hinders clean acceleration from a standing start.

The 0-60 mph time is nothing groundbreaking but very respectable for a 100-plus horsepower naked bike, arriving in 3.10 seconds. The 0–100 km/h sprint takes 3.33 seconds.

This makes it just as quick as most things out there.

The Z900 charges hard to 100 mph, reaching it in just 6.20 seconds – a strong time for the class and quicker than most supersport 600s.

The 0–200 km/h benchmark, often used to measure powerful cars, comes up in 9.57 seconds. Not nad though the litrebike acceleration statys to taper off above this speed and into 600 territory.

In the real world, the Z900 typically runs the quarter-mile in the low 11s at around 125 mph. However, with a good launch and committed riding, it can dip  in the 10s. 

A best of 10.89 seconds with a terminal speed of 129 mph, to be precise.

This means the Z900 can humiliate most supersport 600s either to the quarter-mile line or from a standing start to 130 mph – whichever comes first.

After that, speed, any modern 600 will eat into any lead you may have and pass you.

The Kawasaki Z900 has a top speed of 153 mph

The Z900 is not about top speed, as it’s a naked bike after all, and it is geared for exceptional in-gear acceleration! I

But if you must, you’ll see a top speed of 153 mph on the Z900 right at the redline in sixth, though you’d better be pretty small and in an excellent tuck.
