Engine Performance of 2024 Kawasaki Ninja ZX-4RR

At the heart of the 2024 Kawasaki Ninja ZX-4RR lies a beastly inline-four-cylinder engine that delivers mind-blowing performance. With a displacement of 400cc, this powerhouse generates an impressive amount of horsepower and torque. The precise fuel injection system ensures efficient combustion, resulting in instant throttle response and exhilarating acceleration. Whether you’re cruising on the highway or pushing the limits on the racetrack, the Ninja ZX-4RR will leave you with an adrenaline rush like no other.

The four-cylinder engine in the ZX-4RR is derived, like the rest of the bike, from the 250cc ZX-25R that has been available in some markets since 2020. Both the bore and stroke have been increased, with the bore rising from 50mm to 57mm and the stroke increasing from 31.8mm to 39.1mm. Like the 2023 version of the ZX-25R, the ZX-4RR has an increased compression ratio – the original 250cc version was only 11.5:1, but it has now risen to 12.5:1, and the ZX-4R’s ratio is 12.3:1. Along with the additional 150cc of capacity, these changes result in a peak power of 57kW (76.4hp), which rises to 59kW (79.1hp) when the ram air effect is added at speed. However, it should be noted that Kawasaki states that the power level may vary by market, and while it appears that Europe will get the fastest models, some places will have less powerful variants. For example, in the USA, the ZX-4RR is restricted to 42kW (56.3hp), and in Australia, the power is limited to 55kW (73.8hp). The limiting factor seems to be the revs, with Australian models peaking at 14,500rpm and Canadian versions revving no higher than 11,500rpm. In Europe, the ZX-4R is expected to go beyond 15,000rpm, and the photos show a red line of 16,000rpm, suggesting that Europe will have access to the full 76.4hp.

There are four riding modes – Sport, Road, Rain, and Rider-adjustable – each of which alters the bike’s power map and traction control settings. The ZX-4RR also comes standard with an up/down quickshifter, which is likely to be useful considering how much the rider will need to use the gearbox to keep that engine running at high revs.

A 4.3-inch color LCD dash with smartphone connectivity and various display modes, including a ‘track’ setting that displays lap times and gear position, is standard on all three versions of the bike.

In the UK, only the top-spec RR version and full power will be available, which equates to a quoted power of 57kw/76.4hp @ 14,500rpm and 58.7kw/79.1hp with ram-air at the same 14,500rpm. Peak torque is predictably high in the rev range at 39Nm/28.8ftlb at 13,000rpm. These are impressive figures for a small-capacity Euro5 bike and are far superior to the old ZXR400, which even in a highly tuned and unreliable race spec would only make 75-80hp.

This was a track-only test conducted in the perfect environment of the tight and twisty Calafat racetrack one hour from Barcelona. The 2-mile track with a 600m straight was blessed with perfect conditions, and seven long sessions allowed us to really push the engine to its limits. All 16,000 of them.

With less than 30ftlb of torque and peak power up at 14,500rpm, you need to keep the ZX-4RR revving high. Thankfully, there is a super-smooth up-and-down quick-shifter as standard on the RR model that allows you to keep the rev counter north of 10,000rpm. The 399cc, 16-valve motor loves to rev and is more than happy to be abused, even allowing an over-rev between turns. When you occasionally hit the rev limiter at around 16,000rpm, it’s soft and not too intrusive. Ideally, you don’t want to rev any higher than 15,000rpm; that’s just beyond peak power. Instead, try to maintain the sweet spot between 10,000rpm and 15,000rpm.

This is not a slow bike by any standards. My ZX was clocking 120mph at the end of the 600m straight with plenty of rpm left and another gear to go. I’d estimate that in the right conditions it should be good for around 130mph, which will be no laughing matter if you have one of these little terriers sitting behind you on a track day.

It’s so rewarding and enjoyable to ride the ZX-4RR on track. You can be reasonably aggressive with the throttle, winding it gleefully to the stop. You don’t have to be gentle with the power in the lower gears like you would on a superbike. Instead, stay tucked in and keep those revs coming. Should you get a little too carried away, there is three-stage traction control that uses wheel speed sensors and is not lean sensitive.

We had an official accessory road-legal Akrapovic muffler fitted (£914), which added even more desirability to the package as well as a pleasing rasp. I’ve heard the Superteen race version of the ZX-4RR on track during British Superbike tests, and it sounded great as it screamed towards that sky-high redline. I can’t wait to hear 30 identical bikes racing together.

I thoroughly loved riding the ZX-4RR on track, partly because after seven sessions in blistering temperatures, I wasn’t even slightly fatigued. That’s because the ZX-4RR is so easy to handle; it’s not intimidating. You have time to pick the right line, spot your braking markers, and get that corner just right. You’re not rushing up to corners, scaring yourself on the brakes, and then having to muscle it through the apex. It flows naturally, carries its speed, and then unleashes a riot of revs and wailing exhaust that makes you feel like you are setting lap records!

As this was a track-only test, I rarely allowed the revs to drop below 9000rpm. However, on the cool-down lap, I did play around with the mid-range. It’s not completely lacking in power; you can make progress. But I expect that making a fast getaway from the lights is going to require several handfuls of revs – but that’s what makes it fun, isn’t it? With traction control off, wheelies are just about possible in first gear, but you have to be aggressive.

Handling and Stability of 2024 Kawasaki Ninja ZX-4RR

The engineering marvels of the 2024 Kawasaki Ninja ZX-4RR extend beyond its engine. This sport motorcycle is equipped with cutting-edge suspension components and a rigid chassis, offering exceptional stability and precise handling. The advanced traction control system keeps you in control even during aggressive cornering, while the quick-shifter allows for seamless gear changes without the need to clutch. With superb maneuverability and responsive steering, the Ninja ZX-4RR is designed to dominate every twist and turn on the road.

There are three versions of the ZX-4R available, each with slight differences in their suspension specs. The mid-range ZX-4R SE is equipped with Showa SFF-BP forks, while the ZX-4RR comes with the SFF-BP forks and a Showa BFRC-lite rear shock. However, there is limited adjustability even with the higher-end suspension parts. The SFF-BP forks can only be adjusted for preload, and the base ZX-4R has no fork adjustment at all. On the ZX-4RR, the BFRC-lite rear shock adds compression and rebound damping adjustment in addition to preload adjustment.

The steel trellis frame is a departure from the old 400cc fours of the 90s, which typically used alloy beam frames. It closely resembles the chassis of the ZX-25R, but with a steeper head angle of 23.5 degrees compared to the 24.3-degree rake of the 250cc bike. The trail is also reduced by 2mm to 97mm, but the wheelbase remains unchanged at a compact 1380mm.

Kawasaki Ninja 7 HEV Hybrid Review 2024: The Future of Motorcycling

The weight of the ZX-4RR is 188kg.

As previously mentioned, we enjoyed perfect conditions in Spain, and Kawasaki had chosen to fit Pirelli Diablo Rosso III tires instead of the Dunlop GPR300 that will come as standard in the UK. I was also unsure of what to expect from the ZX-4RR itself, as the original 1990s ZXR400 was a fully adjustable mini superbike with impressive handling and a lightweight alloy frame, unlike the new model’s steel frame.

The first two learning sessions were easy and revealed an impressive base package. Manufacturers often compromise on suspension specifications to reduce costs on lower capacity bikes, but this does not appear to be the case with Kawasaki. The ZX-4RR was instantly comfortable and easy to ride, allowing me to find a decent pace right away.

The front-end feeling, which is crucial for confidence, was excellent and comparable to the benchmark ZX-6R and ZX-10R. Kawasaki had made some suspension tweaks for this track test, adding two turns of preload on the front forks and running standard preload on the rear shock with 1.5 turns of compression and rebound. This adjustment was made to accommodate the high temperatures and grippy tires. Later, I added an additional 0.5 turns of compression and rebound damping on the rear to suit my weight. The changes were immediately noticeable, further proving that Kawasaki had not skimped on suspension quality despite the absence of damping adjustment on the front forks.

Comfort and Ergonomics of 2024 Kawasaki Ninja ZX-4RR

Long rides on a sport motorcycle can sometimes be exhausting, but Kawasaki has taken comfort into consideration when designing the Ninja ZX-4RR. The ergonomics strike a perfect balance between aggressive riding posture and rider comfort. The sculpted seat provides adequate support for both the rider and passenger, while the adjustable footpegs allow you to find your ideal riding position. With wind-deflecting fairings and well-placed controls, you can enjoy extended rides without feeling fatigued.

The compact dimensions of the ZX-4RR might make it a tight fit for larger riders, with the 800mm seat height reasonably low for a sports bike.

There are no claimed economy figures for the European spec ZX-4RR, which won’t be arriving in dealers until late this year. However, the fuel tank, at 15 litres, hasn’t been shrunk like the engine, so you can expect a decent range between fill-ups.

This was a track-only test; therefore, it’s hard to judge comfort and long-distance use. However, despite its compact proportions, the ZX-4RR is reasonably roomy. I’m nearly 5ft 7ins and didn’t find it too cramped, and there weren’t many complaints from the taller riders on the test. For me, it’s more comparable to a 600cc supersport, certainly larger and roomier than the ZXR400 from the 90s.

The view from the seat is neat: switchgear that, like most Kawasakis, is relatively simple, and a clear 4.3 TFT dash that has connectivity. There are four riding modes – Sport, Road, Rain, and Rider (manual) mode, which changes the power (full or low) and KTRC traction control (levels 1 to 3 and off). There’s an additional Circuit Mode that changes the screen to give a large lap timer and rev counter, which is ideal for track day fun and somewhat addictive. Preload adjustment is on the right-hand 37mm Big Piston Fork.

Styling-wise, the ZX-4RR is very much a baby brother of the Ninja ZX-6R and ZX-10R and could easily be mistaken for one of its bigger siblings. As much as I like the old ZXR400, I equally like the new ZX-4RR. Despite being a small-capacity bike, it’s a machine you can be proud of.

Price and Availability of 2024 Kawasaki Ninja ZX-4RR

The 2024 Kawasaki Ninja ZX-4RR is undoubtedly a high-performance machine loaded with advanced features, but what about its price? While Kawasaki has not yet released official pricing details for this model, it is expected to be competitively priced within its segment. As for availability, enthusiasts around the world eagerly await its release, which is expected to be in late 2023 or early 2024.

What is the price of the 2024 Kawasaki Ninja ZX-4RR? It is £8699, which is below what most people expected. When the announcement came earlier this year, the original guesses were £9000 – £10,000. In fact, Kawasaki has already taken deposits from customers who were expecting a higher price tag. Yes, that is a lot of money, but it is nearly £2000 below a ZX-6R, which is a significant saving. Quoted PCP prices with a 20% deposit are just £105 a month.

Back in the 90s, there was a decent selection of 400cc machines – some of them grey imports, others official – but those have long gone. Today, the competition for the rev-happy Kawasaki has to come from their own garage in the form of the ZX-6R or Ninja 650 (£7389). Alternatively, Yamaha’s R3 (£6405) or KTM RC390 (£5699) could be considered. Both the Yamaha and KTM are cheaper, but neither can match the spec and power of the ZX-4RR. The Kawa has nearly double the power of the Yamaha with ram-air.

You could make a case for Yamaha’s R7 (£8910). The 689cc twin will offer considerably more torque and almost the same power, and it looks sharp too. We also can’t ignore Aprilia’s RS660 (£9650) either. If you want a small-capacity sports bike, then this is the market leader.

Ultimately, Kawasaki’s new ZX-4RR’s position in the market depends on where you are coming from. For newer riders, it could be compared to many bikes, from Yamaha’s learner-friendly R3 to Kawasaki’s own ZX-6R. For older folk like me who remember the original ZXR400 and don’t want a 200bhp superbike anymore, its rivals could be any of the myriad machines we turn to when looking for a new style of two-wheel kicks.

Verdict of 2024 Kawasaki Ninja ZX-4RR

The 2024 Kawasaki Ninja ZX-4RR is set to revolutionize the sport motorcycle industry with its breathtaking design, unparalleled performance, and cutting-edge technology. Whether you’re an adrenaline junkie craving speed or an avid rider seeking a thrilling experience on two wheels, this motorcycle has it all. Stay tuned for more updates on pricing and availability, and get ready to unleash the ultimate powerhouse on the road with the 2024 Kawasaki Ninja ZX-4RR!

The ZX-4RR has some big shoes to fill (although I recently rode an original ZXR400 from the 1990s and wasn’t overly impressed, such is the march of time and progress). Nevertheless, the new ZX-4RR seamlessly picks up where the original left off and is also neater, faster, safer, roomier, and far easier to ride.

Kawasaki has been brave to produce such an unusual bike for the times – it’s the only sports 400 on the market – but I’m pleased they have. I don’t think the ZX-4RR will gain a reputation like the original, but it’s great fun, loves to rev, is easy to ride, and forgiving too; new sports bike riders are going to love it.

Equally, experienced riders like me can tweak the suspension, tuck in behind the low screen, and have some old-school fun. I rode the ZX-4RR on track all day, rode hard every lap, used all the power and didn’t feel tired at the end. I can’t remember doing that on any other quality sports bike recently. The small-capacity sports bike is back – thank you Kawasaki.
