2023 Kawasaki Ninja ZX-4RR Review

- We review the 2023 Kawasaki Ninja ZX-4RR, featuring a liquid-cooled 399cc inline-Four with DOHC and 16 valves, at the Thunderhill Raceway in Northern California.
The ZX-4RR has the potential to reinvigorate the sportbike market, providing a gateway to high-level performance in a package that is both tamable and attainable. Its power naturally pales in comparison to a fire-breathing ZX-10R or even a ZX-6R, but the 124 mph shown on its speedometer at the end of Thunderhill Raceway’s front straight demonstrates its potential for speed.
Unfortunately, EPA noise regulations mean that the 4RRs coming to North America are restricted, most likely by way of the electronic throttle valves at high revs. Our 4RRs produce peak power around 11,500 rpm according to a dyno chart supplied by Graves Motorsports, just shy of 60 hp at the rear wheel. Upconverting that number to a rated-at-crankshaft figure translates to about 65 hp, at least 10 ponies down from its Euro spec.

absolutely love mine, even with the power restricted in the US it is so much fun on the streets
my graves slip on makes it sounds bad to the MF bone
This is what I experience. I never want to stop riding my ZX4RR. I will empty the tank on every ride. This has helped my diet enormously. I don't have time to stop to eat. I am having a blast on all the curvy back roads around were I live. It's about a 5hr ride to the smokies from where I live and I'm planning to a ride there this spring. I've ridden a Triumph Street Triple to the Smokies before. It was great fun on the interstate. By the way, I just turned 70.
You're an inspiration for us all!
Great to see Kevin Duke back. Looking forward to seeing more tests in the future!
Such a cool little bike.
Amazing track bike I’ve already seen a handful run at the track and the owners speak highly of them.
Great vid. Said more useful info in 5 minutes than most reviwers have said in 25. Love the bike too, less is most definitely more! It's like a sports bike simulator as it does everything the bigger sports bikes do a sensory way but in a more useable street appropriate package.
Glad you appreciated the concise presentation! I already spend too much time in front of a screen, and when I see a 25-minute video about a bike, I move on. Click that subscribe button to stay tuned!
I'm going to my first track day in Shitfuck, Kansas on this bike and I leave in like 15 hours. I'm nervous as all heck.
Hope it went well man ride at 75% of your go up toy all day way less likely to crash and you’ll still vastly improve.
