What's mean, green, and ready to shake things up?

The 2023 Kawasaki Ninja ZX-4R Supersport

A mid-weight, higher-performance four-cylinder Kawasaki Ninja is on the way in the form of the Ninja ZX-4R, as well as the ZX-4R SE and the ZX-4 RR variants. Expect more hype and excitement drummed up for this bike later in the autumn of this year. But for now, we've got some of the details that we're sure you're chomping at the bit to know...

If you'd like to know specifications, you'll find them at the bottom!

It means business

The most powerful of the family will be equipped with a high-output engine delivering an insane 80 PS in a lightweight chassis, for superior cornering performance and a weightless feeling with acceleration. This bike is premium, aggressive and refined. Kawasaki are calling it an "apex predator" and an absolute must to experience whether you're a seasoned rider or a biker new to the joys of supersport and smaller race-style bikes. Whichever category you fall into... you're in for a real treat.

It's got serious power

What makes this bike really go and gives it its power is a newly developed 399cc liquid-cooled, parallel 4-cylinder DOHC engine, based on that of the ZX series. This gives a maximum output of 57 kW (77 PS) and 59 kW (80 PS), thanks mostly to Kawasaki’s world-famous Ram Air system, located in the centre of the upper cowl, providing styling that is instantly recognisable as part of the Ninja ZX series.

It's full of tech

Keep an eye on how the bike is performing via the 4.3-inch full-digital colour high visibility LCD screen. Enjoy "track mode" that displays lap times, gear positions, and RPMs from 10,000 rpm and above, as well as Kawasaki's "RIDEOLOGY" app that can be downloaded to your phone and used for a variety of functions, including recording GPS route information.

We can introduce you to a selected panel of lenders, which includes manufacturer lenders linked directly to the franchises that we represent. An introduction to a lender does not amount to independent financial advice and we act as their agent for this introduction. Our approach is to introduce you first to the manufacturer lender linked directly to the particular franchise you are purchasing your vehicle from, who are usually able to offer the best available package for you, taking into account both interest rates and other contributions. If they are unable to make you an offer of finance, we then seek to introduce you to whichever of the other lenders on our panel is able to make the next best offer of finance for you. Our aim is to secure the best deal you are eligible for from our panel of lenders. Lenders may pay a fixed commission to us for introducing you to them, calculated by reference to the vehicle model or amount you borrow. Different lenders may pay different commissions for such introductions, and manufacturer lenders linked directly to the franchises that we represent may also provide preferential rates to us for the funding of our vehicle stock and also provide financial support for our training and marketing. But any such amounts they and other lenders pay us will not affect the amounts you pay under your finance agreement, all of which are set by the lender concerned. If you ask us what the amount of commission is, we will tell you in good time before the Finance agreement is executed. All finance applications are subject to status, terms and conditions apply, UK residents only, 18’s or over. Guarantees may be required.
