The legend of the 90s is making its return in modern guise. When this shows up, bye-bye parallel twin 250cc & 300cc sportsbikes. Current 2-pot Ninja 250 will do 12500RPM... if the old ZXR250 is anything to go by, an inline 4 250 engine will rocket up to 18000RPM and scream just like an F1 car.

The real killer however would be a 400cc inline 4 version, CKD.. if there is even such a plan in the works. If the old ZXR400 is anything to go by, that ought to be about 14000RPM, 60+ horses in a package not that much bigger than a 250cc bike - sounds plenty fun!

In-line four-cylinder Kawasaki Ninja ZX-25R ready in prototype form

The rumours about the in-line four-cylinder Kawasaki Ninja ZX-25R have been around for quite some time now. In a new development, Indonesian website Gridoto claims that this rumoured quarter-litre motorcycle is ready in prototype form at the PT Kawasaki Motor Indonesia’s factory.

The report adds that the prototype motorcycle is equipped with a racing exhaust. The sound produced by the bike is claimed to be equivalent to that of a big bike. The details are scarce, but if a new model is under development, we can expect to see improved performance numbers. The two-cylinder Ninja 250, which is currently on sale in select international markets, draws 39 hp at 12,500 rpm and 23.5 Nm of peak torque at 10,000 rpm from its 249 cc liquid-cooled motor.

The quarter-litre four-cylinder model, if launched, will compete with the Honda CBR250RR and the Yamaha YZF-R3. Both its rivals feature a twin-cylinder engine.

The new engine specifications will be backed with updated hardware that should target the Honda CBR250RR. The quarter-litre from Honda packs upside down front forks and ride-by-wire tech. Kawasaki can try to integrate those features into the four-cylinder Ninja 250. The current generation model already gets full LED headlight. The semi-digital instrument console with an analogue tachometer can stay.

Like the Kawasaki Ninja 250, the rumoured Kawasaki Ninja ZX-25R should feature single disc brakes on both wheels, but maybe with a larger rotor. Dual-channel ABS will handle the safety department. The world premiere may take place at either the 2019 Tokyo Motor Show or the EICMA 2019 in the final quarter of the year.

Meanwhile, in India, Kawasaki has commenced the pre-bookings for the 2019 Ninja ZX-10R, its litre-class supersport model. With the MY2019 update, the Ninja ZX-10R's engine's maximum power has gone up from 200 PS to 203 PS. The bike can be pre-booked with a deposit of INR 1.50 lakh.

Yup, can't expect it to be cheaper in any way. 2 more cylinders doesn't end there. There's technology to be added on to make it all work and there is a development cost as well...

Well let's see what Kawasaki thinks of it.

The way I look at it, the 2-pot 250cc market is getting crowded coz all the major players are throwing everything into it. Kawasaki might decide the need to create a differentiated offering far outweighs everything else, which may justify bringing back the inline 4 250cc pocket rocket and adjusting the 2-pot 250cc line-up to accommodate it.

That might then serve as a stepping stone towards considering reintroducing the inline 4 400cc class.

It's early days yet, but it's encouraging to hear abt the possibility of this category of bikes making a comeback. After all, it has been 20 bloody years.

Surely this can't be bad news at all.

There will definitely be some R&D cost that this bike will have to recoup, but then it isn't as if Kawasaki needs to sink serious money designing testing & tooling for a brand new engine from scratch like Yamaha did with its triple.

They already have that engine design as a base to improve on. Just like how they developed the current gen 2-pot engines that trace their origins to existing GPZ & ZZR/EL engine designs of the 90s.

Was posted recently.

Howver, it most likely won't be the ZX-25R, but the 2020 W800.

The super bombastic English used in the video is typical of Indian writers.

Dyno run claims to show 41.8bhp at 15000RPM.

The original ZXR250 made 45 horses at 15,000RPM.

2-stroke 250s like the RGV250 & RS250 pushed out 70 horses at 12000RPM.... if you can keep feeding em expensive synthetic 2T....

Yamaha beh tahan edy. They might launch a competitor and give the ZX-25R a run for its money.
