ZX-4R

After months of speculation, Kawasaki has officially announced its latest sports bike line-up with the all-new Kawasaki ZX-4R. 

  • The Kawasaki Ninja ZX-4R is the latest inline-four screamer to join Team Green. 
  • The Ninja ZX-4R features the same high-tensile steel trellis frame as the ZX-25R. 

Available in three variants, ZX-4R, ZX-4R SE and ZX-4RR is powered by the firm all-new 399cc inline-four, water-cooled 4-stroke with DOHC unit that’s capable of pumping 79.1hp with Ram-Air. 

Similar to the ZX-25R, the 400cc screamer also offers a generous rev limit of over 15,000rpm and is fitted with the same trellis (high tensile steel) frame. 

Power is fed from the bike’s 15-litre fuel tank and is regulated by a 6-speed manual transmission with a final chain drive.

The suspension comes from Showa with SFF-BP forks at the front and a horizontal back-link at the rear. However, the suspension package is what sets the three variants apart, with the base model getting the SFF-BP forks as mentioned above, while the SE and RR feature front forks with preload adjustment. The RR is also equipped with Showa BFRC-lite rear shock similar to the one found on the ZX-10R. 

Braking is done via radial-mounted callipers mated to a dual 290mm front brake disc and a single 220mm disc at the rear. 

Electronic-wise, the Ninja ZX-4R features all-around LED lighting, Kawasaki Traction Control (KTRC), 4-power modes (Sport, Rain, Road and Rider), a two-way quickshifter (SE and RR) and a 4.3-inch LCD colour display with integrated ‘Track Mode’. 

According to Kawasaki USA, the Kawasaki Ninja ZX-4R is confirmed for release in mid-2023 with an official selling price of USD 9,699 (RM41.3k). 

It is no secret that Kawasaki plans to introduce the Ninja ZX-4R in 2023, as confirmed by the latest report in Japan.

  • The current ZX-25R is set to be joined by the bigger ZX-4R.
  • A new VIN decoder suggests that the ZX-4R will be available in two trims, ABS and non-ABS.

Japanese publication, Autoby managed to get an inside scoop regarding the 399cc inline-four cylinder motorcycle.

Now, thanks to the latest report by Motorcycle.com, a new Vehicle Identification Number (VIN) decoder released by the U.S. National Highway Traffic Safety Administration has confirmed that Kawasaki will indeed introduce the Ninja ZX-4R model for 2023.

This means that unlike the ZX-25R – currently only available in Japan and other Asian markets due to emission restrictions – the Ninja ZX-4R will make its way to the U.S. and Europe.

The VIN decoder was dated March 22, which stated the following listings that you can check out HERE.

The first row on the first column listed ZX400PP. According to Motorcycle.com, the Z.X. refers to a high-performance sportsbike, while the 400 indicates the engine capacity followed by the letter “P” representing 2023MY.

The complete VIN decoder listings – specifically the first two rows of the seventh column – clearly state the number of cylinders of the ZX400PP and ZX400SP.

The ZX-4R could be offered in two trims, ABS and non-ABS, hence the ZX400PP and ZX400SP.

Like the ZX-25R, the upcoming ZX-4R is likely to present a significant increase of power over the Ninja 400’s 48hp, with rumours going around suggesting the 400cc inline-four cylinder motorcycle to put out around 59hp.

The highly anticipated Kawasaki ZX-4R looks to be on its way, as confirmed by the latest reports.

Talk of a new 400cc inline-four sports bike has been around for quite some time, ever since the introduction of the quarter-litre ZX-25R.

Japanese publication, Young-Machine – known for getting the latest insight for Japanese motorcycles – has made the ZX-4R its latest cover for April with a render that is likely to be close to the final product.

The headline also suggests that Kawasaki is prepping for an official reveal very soon.

While the ZX-4R is somewhat related to the ZX-25R, the former will follow the ZX-10R design, prominently the sunken headlight and the air-duct.

Reports also suggest that the new bike will feature premium components, from Kawasaki Traction Control (KTRC), USD forks and riding modes.

We have yet to secure any information regarding how much power it might produce, but rumours have that it could be around 75hp and above.

The Kawasaki ZX-25R is almost a walk down memory lane, taking us back to the glory years of the 4-cylinder screamer of the 80s and 90s.

Although we have yet to see the bike making its way to Malaysia, we are still hopeful that it just might, under the new management of MODENAS.

Nevertheless, Kawasaki is already working on another tempting machine in the form of a more powerful 400cc version, retaining the high-reving appeal of the original 1990 ZXR400.

The rumour first came out during the global introduction of the ZX-25R itself; however, reports in Japan have confirmed that the ZX-4R is sure to be launched soon.

Moreover, Kawasaki already filed a patent in 2019 showcasing a design that states “preferably applied to a vehicle having four-cylinder 400cc engine.”

Based on a rendered image shared, the upcoming ZX-4R is expected to be fitted with the same components from the existing ZX-25R, including the tubular steel frame and the banana swingarm.

According to reports, the ZX-4R will feature a revamped front and headlights, heavily inspired by the latest ZX-10R superbike together with the ZXR400 paint scheme.

Since the ZX-25R makes 50hp @ 15,500rpm with Ram-Air, the ZX-4R could churn out close to 80hp.
