Well lads and lasses, today I read on a czech motorcycle site, that Kawasaki is working on another ZXR250 and they say the prototype is in it's final stage. All I could find so far is, that the zxr should have a in-line four cylinder four stroke engine with 16 valve head. Along with the in-line four cylinder engine version there's being developed a twin cylinder engine version. Also, they say the bike's gonna be most likely produced in Indonesia, which could mean they're gonna go with the twin cylinder engine.

Now it's up to bosses in Japan, what's it gonna be. Thumbs Up

For those less educated or just ignorant people, here are something about the original zxr 250: https://en.wikipedia.org/wiki/Kawasaki_Ninja_ZX-2R

Specs ('89-'90) NOT THE NEW VERSION FROM 2015
Engine: Liquid cooled, four stroke, transverse four cylinder, DOHC, 4 valves per cylinder
Displacement: 249ccm
Bore x stroke: 49 x 33.1 mm
Max power: 45 hp 32.8 kW @ 15000 rpm
Max torque: 2.6 kgf-m 24.5 Nm @ 11500 rpm
Transmision: 6 speed gearbox
Dry weight: 144 kg

Probably a hoax - the 300cc seems to be the sweet spot within the EU licensing laws nowadays.

As for moving a few letters around, ninja 300, 300r, zx300r, zxr300 it just doesn't make a difference... They'll call it what they want and it'll bare little relation to the bikes of the past.

45bhp? Aren't current 250's barely scraping 30 these days? And probably much heavier as well.

I googled around and many motorcycle sites have quite the same info. By the way, the specs are marked as 1989-1990 and even the picture is of the 1989-1990 version. So don't get overexcited yet. Thumbs Up

The CBR and YBR are single cylinders, Ninja 250 is a twin. The smaller you make the cylinders, the less they weigh and therefore the faster the engine can rev. Power = torque x engine speed. So for the same displacement, if you can make the engine rev higher then there's more power. Honda once made a five cylinder 125 a loooong time ago and nothing could touch it on the track.

I will want if it's four cylinders. Those figures ain't A2 compliant though Razz

Not so much (although part of it). More cylinders means a shorter stroke without the bore getting silly. Shorter stroke means the piston has less distance to travel for one revolution of the crank. Mean piston speed is pretty much the limiting factor.

Suzuki were building 4 cylinder 125 bikes in the 1960s. Peaky as hell, hence needing a 12 speed gearbox. Even a 3 cylinder 50cc bike with a 14 speed gearbox.

All the best

We will get the boring option. The emerging markets aren't interested in the small cc sports bikes, but they are interested in frugal commuters.
