Kawasaki Recalls Ninja ZX-4RR KRT Edition Over Potential Alternator Failure

Over in the United States, the Ninja lineup kicks off with the good ol' 400 that combines a liquid-cooled parallel twin engine with a slipper-clutch transmission. Priced at $5,299 (before taxes and extras), the 400 can also be had as the Kawasaki Racing Team-inspired KRT Edition.

Available from $9,699 under the Ninja ZX-4RR KRT Edition moniker, this version has been hit by a safety recall. A grand total of 991 motorcycles are called back in the United States of America, namely those manufactured from January 11 to March 29 this year.

Described as a supersport bike, the KRT Edition may experience a malfunction with the alternator. Documents filed with the National Highway Traffic Safety Administration describe the failure as follows: the connection between the alternator's rotor and crankshaft may loosen, therefore resulting in stalling.

Kawasaki says that certain alternators had their rotors installed incorrectly during the manufacturing process, with Kawasaki listing itself as the supplier of the suspect parts. Unfortunately, no remedy has been decided at press time. Kawasaki Motors Corp. USA hasn't provided a schedule for owner notification either, but nevertheless, affected owners may contact customer support at 1-866-802-9381 for more information. Alternatively, owners can check if their bikes are called back by running the VIN on the NHTSA's website.

Given the condition presented earlier, the remedy will come in the form of a replacement alternator. One assembled properly, that is. Knowing the Japanese manufacturer, an update on recall 23V-515 with said remedy should be published in August at the latest.

Codenamed ZX400SPFNL, the Ninja ZX-4RR KRT Edition is a bit of a bargain compared to the big-boy H2 SX (starting at $28,000) and race-ready H2 R (starting at $57,500). Despite the huge pricing differences between it and the Ninja's hypersport line of motorcycles, the KRT Edition isn't a bad motorcycle. 400 cubes are more than enough for dailying, and they're also good enough for a fun ride on a winding road.

What are you getting for your hard-earned cash, though? For starters, a chassis inspired by the World Superbike Ninja ZX-10RR racing motorcycle. At home in the urban jungle and on the open road, the ZX-4RR KRT Edition further sweetens the deal with a ram-air duct located on the left-hand side of the fork.

Equipped with a 4.3-inch TFT digital instrument cluster that boasts Circuit Mode if you're into lap timing and track day-related information, this version of the Ninja can be paired to your smartphone via the Rideology app for both Android- and iOS-running smartphones.

Painted in Team Green's trademark color, the KRT Edition comes exclusively in Lime Green with Ebony touches here and there, plus cool decals throughout. Tipping the scales at 414.5 pounds (188 kilograms), this fellow is covered by a 12-month limited warranty.
