Adding more love to the A2 licence middleweight category, Kawasaki have ditched the old Z300 in favour of a new Z400 powered by the engine from the Kawasaki Ninja 400.

The old Kawasaki Z300 took a bit of flak for coming in well under the A2 power limit but that should be no issue with the new bike which is both more powerful and lighter weight than the old model.

The styling is pure classic Kawasaki, with the trellis frame shouting H2, while also giving the bike light and predictable handling. As expected for a bike aimed at new riders the Z400 has a low seat height and an easy to use slip assist clutch.

It’s also bristling with modern tech such as LED lighting, a digital speedo, gear position indication and the infamous ‘balls of wool’ economical riding indicator.

Fantastic A2 motorcycle. Perfect blend of (capped) performance, comfort, economy, weight and Zed styling. It even sounds quite good too, with the standard exhaust and that slipper clutch on the downshifts. I choose it over the Duke (another fine bike no doubt) as it looks so much easier to spanner on and to keep clean.

Ride quality & brakes 5 out of 5

The brakes are excellent. I have a few older bikes that I do service myself and they could all pass an MOT on any day of the year, their brakes however, seem wooden in comparison. I read some reviews prior to buying that said the reviewer thought the suspension was quite harsh, but again, in comparison to my older bikes, this seems to be a bit softer and more comfortable.

Engine 5 out of 5

I have only just finished the worst of the break in period, so still taking it relatively calmly on the Zed. However. the signs are good. It has that feel of an engine that wants to be set free. Lets be honest, it only has 45bhp (but I believe, unusually, that is at the back wheel, not off the crank...only something I have read though), that taken into consideration, it pulls.

Reliability & build quality 4 out of 5

Only going to award 4, because it is still being run in, so it too early to praise to highly! Seems to be well bolted together though. Only gripes are the stock mirrors are terrible and the stock indicator stalks seem cheap (they vibrate madly, even at tick over), oh and I needed some grip puppies, as the bars feel very thin.

Value vs rivals 5 out of 5

Very frugal to run, petrol wise. Too early to tell with other consumables, but as I do my servicing myself, it shouldn't be bursting the bank.

Equipment 4 out of 5

ABS, slipper clutch, gear indicator, nice big rev counter. More gizmos than I want, or need in all reality, but I'll take them and to be fair the slipper clutch is a nice addition. An extra £900 (check out Norton performance in the USA) can buy a significant performance hike too, although it may invalidate your insurance!

Buying experience: Superb. Brought as a pre-reg'd bike from M&P in Swansea. I paid the advertised price of £4099, which included free delivery. You'd pay (quite a bit more than tha)t, for several new 125cc bikes on the market). Fantastic value.
