About the Kawasaki ZX25R

Introduced in Japan and Launched in Indonesia

The supersport bike world has been anticipating the Kawasaki ZX25R for the past couple of years. You can say that it is the most anticipated motorbike of the year. Finally, it has been introduced in Japan and launched in Indonesia. The world has finally set its eyes on this marvelous wonder.

It was first seen in the Kawasaki Motorcycle Fair 2020 in Japan. The Kawasaki Ninja ZX25R was eventually launched in Indonesia shortly thereafter. Why in an Asian country? The reason is primarily that it was designed for the Asian Market. Most riders in these parts are on sub-400cc motorbikes.

Four Cylinders

But why four cylinders? The market in South East Asia wants more options. And this is where the Kawasaki Ninja ZX25R comes in. It will probably be made available in the United States for those looking for smaller bikes with big bike capabilities.

What Kawasaki tried to do was to scale down the traditional sportbike. And by doing this, they were able to sell the ‘big bike’ feel and its characteristic sound without the extra big engine displacement for less money than the usual costs of big bikes.

Body Is Suspended on a Trellis Frame

It seems that this little ‘big bike’ comes with all the right parts. The body of this sportbike is suspended on a trellis frame that is made of high-tensile steel. It comes with functional features like the following:

  • Quickshifter,
  • Several ride modes,
  • Radially mounted monoblock brakes with ABS,
  • Traction control, and many more.

An in-line four-cylinder propels this supersport bike, 250cc gasoline engine mated to a 6-speed transmission. Kawasaki claims that their test models can generate 50.3 brake horsepower (bhp) at 15,500 RPM. Japanese models, though, can produce a more modest 44 bhp.

On test models such as the Kawasaki Ninja ZX25R Carbon, which was tested in the U.K., the super sportbike achieved a top speed of 190 kilometers per hour (kph). That is around 118 miles per hour.

Kawasaki Quick Shifter

This motorbike also has a downshift that sounds very aggressive. That is because it is fitted with a KQS or Kawasaki Quick Shifter. For a four-cylinder engine, this 250cc unit is really very compact. It could generate high revs. This engine redlines at around 17,000 RPM.

With all these high-level qualities, it is no wonder that the Kawasaki ZX25R is quite expensive. If there is ever going to be a Kawasaki ZX25R (USA), it would be priced at around $9,000 to $10,000. Right now, its price in some Asian countries is no less than $8,000. Some say that this bike could be made available in the US on a pre-order basis.

That price is brought about because it costs a lot of money to make an engine that can produce so much power using just a small displacement. Creating a four-cylinder engine instead of just a parallel-twin engine will also up the price.

Kawasaki ZX25R Features

While the Kawasaki ZX25R has many functional features, you may focus on a few of its salient features. They make this supersport bike worth considering:

1. Strong Performance

The Kawasaki ZX25R is fitted with a 249cc inline four-cylinder engine which can deliver 50 hp. at 15,500 RPM and 22.9 nM of torque at 14,500 RPM. These figures are not that much, but it is already big and powerful enough for beginners and intermediate riders. They can use this bike to improve their riding skills on the tracks.

Gear shifts are quite smooth with its 6-speed manual transmission because it has an assist slipper clutch. For even smoother shifts, Kawasaki added its own quickshifter to the mix. So attacking corners on the track is made easier.

The engine’s multi-cylinder configuration and low displacement enable this sportbike to deliver a very linear powerband and revolutions up to a maximum of 17,000 rpm. If the ram air intake is increased further, it will also increase its power output to about 51 hp. This makes it more powerful than all other rival bikes that are powered by 250cc engines.

By comparison, Kawasaki ZX25R’s nearest rivals, the Yamaha R3 and the KTM RC 390 have power limits lower than 50 horses. The Yamaha R3 can only produce up to 42 hp, while the KTM RC 390 can only manage a maximum of 43.5 hp.

2. Mileage and Speed

The Kawasaki Ninja ZX25R can get 58.8 miles to a gallon of fuel or 25 kilometers to a liter. It can get from zero to 100 km/h in just about 6 seconds. That’s about 62 miles in 6 seconds. This superbike can attain a top speed of 190 km/h. That’s around 118 mph.

3. Strong but Flexible Chassis

The engineers developed the chassis of the ZX25R at Kawasaki by using advanced dynamic rigidity analysis. This process enabled them to save weight and optimize the frame’s rigidity where it is needed the most.

The lightweight trellis frame of this supersport bike was designed meticulously by the Kawasaki engineers to possess the right combination of flexibility and strength. That is why it can be considered an agile bike with superbike handling qualities.

4. High Quality Suspension

The Kawasaki ZX25R comes with first-class suspension components. Kawasaki claims that the suspension of this superbike is the same as the one they use on the ZX-10R, the company’s flagship model.

The suspension components of this bike include 37 mm inverted forks at the front and a horizontal back-link rear suspension setup from Showa. There’s a wide range of adjustability for the bike’s suspension, both front, and back. Riders can set the suspension at their desired setting according to the weather and track conditions.

5. More Bang for the Buck

The Kawasaki ZX25R offers more value for your money. Its engine is meant to deliver power, performance, and riding characteristics as its bigger and more powerful siblings and a more approachable and affordable package.

This motorbike can be said to be sitting on a class of its own when talking about performance-oriented machines. There is no other motorbike in the market that offers the kind of performance and the thrilling sound of its relatively small engine package.

It is, therefore, quite understandable that the Kawasaki ZX25R commands a steep price. This bike is almost as pricey as its middleweight sibling, the Ninja 650. But considering its superb characteristics and capabilities, the price is just right for the value it offers.

Other Features Worth Mentioning

Here are some of the other features of the Kawasaki ZX25R that you need to know:

1. Curb Weight

For the base model, the curb weight is set at 396 pounds (180 kg.). If the unit has an ABS, another 5 pounds will be added to its overall weight.

2. Body

The beautiful body of this superbike is suspended on a Trellis frame with upside-down front forks.

3. Suspension

This bike has a Showa suspension, with 37 mm SFF-BP separate function front big piston forks. The rear suspension consists of a horizontal back-link rear shock with spring pre-load adjustment. The Kawasaki ZX25R offers a 120 mm suspension travel in the front and horizontal back-link suspension with this suspension system.

4. Riding Modes

This bike has three riding modes, namely:

  • Race,
  • Road, and
  • Sport modes.

5. Instrument Console

The instrument panel of this superbike contains the following:

  • Digital odometer,
  • A digital fuel gauge,
  • An oil change indicator,
  • A digital speedometer,
  • A trip meter, and
  • A tachometer.
