Small capacity 4cyl bikes?

[TheInternet]

The CB500 Super Four announcement got me wondering if there have been any other <600cc four-cyl bikes in recent times?

I'm guessing they've all been emissioned off and also pointless in the A2 age, and doubt we'll see that Honda here.

Kawasaki did a Ninja 400 a couple of years ago. Cool bike.

They sell the Kawasaki ZX-25RR but only in the South East Asia markets.

Yeah this...

No interest in Europe so it seems

There's supposed to be a Z400RS coming out next year....

In the early or mid-90s I had a go on a GSXR250 import.

Astonishing thing to ride, but, as I best remember, redline at 18,000+ and no torque below about 9000.

Think the Kove 400 sportsbike is a 4 cylinder

Shame if so, as the smaller capacity, simple stuff (e.g. Royal Enfield Interceptor) seems to do well. I’d certainly take a good look at one - I really like the CB1000 but feel it’d be overkill for what I want. This would be ideal.

Benelli did a 4 cylinder 250 in the late 70’s.

Kawasaki do a Ninja ZX4-RR (I have one) and it is a lot of fun.

I think part of the issue is that everyone associates small capacity bikes with being cheap bikes. Making a four cylinder engine does actually just cost you more than making a single or twin, there's no way round it.

A multi cylinder bike will give more power but most people prefer to just buy a bigger bike.

Back in the 90s there were various licencing reasons around the world that seemed to make it worthwhile. I remember being in Australia in the early 2000s and there was loads of cool 250s (ZXR, GSXR, CBR - all inline fours) as they could ride them on some kind of learners licence. There were a few grey import 250 fours kicking about round here but generally the 250 two-strokes were seen to be more on a par with 400 four strokes (which is how they paired them for club racing) so probably less popular as 400s were readily available.

ZX4RR fits the bill, revs like a mutha too.

Just bought a Honda CB 400 1994 grey import lovely condition haven’t road it yet.

This is my ZX4-RR
