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).
