After the success of Kawasaki’s Ninja ZX-25R, the Japanese firm is said to be working on another 250cc four-cylinder engine.

The ZX-25R was a huge success since its launch and probably the most powerful quarter-litre bike to date.

It’s probably thanks to the Ninja success, Team Green is rumoured to be developing a naked version of the 250cc screamer.

Similar to the ZX-25R, we can assume the quarter-litre naked bike feature the same high-spec goodies such as premium inverted forks, radially mounted brake callipers and quickshifter.

Nonetheless, the new motorcycle will feature the same 250cc four-cylinder engine capable of producing 51hp @ 15,500rpm and 22.9Nm @ 14,500rpm.

Based on how strong the ongoing rumour is, we can expect that the development of the new motorcycle is already underway.
