2024 Zx-4r Top Speed. It breached 200kmph (120mph) with ease, only to make us. This impressive top speed is achieved thanks to its 399cc.

As mentioned, the 399cc engine produces a claimed maximum output of 74.8hp (55kw), the figure chiming in at 14,500rpm, but the ram air system pushes this a smidge further to 77hp (56.7kw). Without getting anywhere near top speed, the reduced power output stood out versus the honda, too.
