Starting with the brilliant Z900 as its base, its no surprise the 2017 Kawasaki Z900RS matches performance with looks. It oozes '70s Z1 charm, detailing and mixes it with modern technology, easy speed, light controls, superb build quality and fastidious attention to detail. There’s enough performance for experienced riders to enjoy and for new riders it’s a piece of cake to jump on and live, or relive, your '70s dreams.

It's a different model to the Kawasaki Z900RS Cafe, which as the name suggests is more geared towards cafe racer styling. There's an online community for owners to join on Facebook: Kawasaki Z900RS owners.

2020 Kawasaki Z900RS colours

In September 2019 Kawasaki introduced three striking new colours for the Z900RS for the 2020 model year. You can see one of the new liveries below, which echoes the style of the 1973 Z1A, which replaced the first-generation Z1. The bike will also be available in either a black or grey design - both new for this year.

Kawasaki have modified the Z900’s upper frame so they could fit the tank and seat horizontally, like the original ’72 bike. As well as its modified chassis, higher spec monoblocs trump the Z900’s brakes and a three-way switchable traction system and retro-styled Dunlop GPR-300 tyres are other new editions.

Light, accurate town handling continues when you hit the open road. Suspension springs are stiff, so the Z900RS is more composed the harder you ram it into corners and fully-adjustable forks and ZX-10R-style horizontal rear shock and linkage are lightly damped, so the big Zed feels floaty when you up the ante, but they’re set to give a smooth ride and easy, accessible low-speed handling.

Original equipment tyres lack grip and confidence when you push on, but are fine for normal riding and there’s no problem with ground clearance, braking feel and power. But we’d love to spend a day twiddling the suspension settings and fitting stickier tyres to see if it could match the composure of track-ready retros like Triumph’s Thruxton R and BMW R nineT.

All-day riding is relaxing and the back-friendly, upright bar position is natural. There’s plenty of seat-to-peg room for the tall and it’s low enough for the short (a 35mm lower accessory seat available to drop you down even further).

This is more than just a Z900 with flares, because there’s even more going on under the skin. Kawasaki have bolstered low to midrange power for everyday riding, which is at the expense of the standard bike’s top end clout, but the reality is you never miss it in the real world. First gear is shortened and the exhaust is tuned for bass-laden ear destruction, as well as grunt.

There’s no lack of speed in the Zed’s armoury and with the traction control turned off it will do the kind of Evel Knievel wheelies the Z1 could only dream of back in the 70s. The slip and assist clutch, gearbox and twistgrip are all beautifully light and easy to operate, but the power delivery is aggressive from a closed throttle, which makes tackling tight corners and slow riding tiresome.

A smooth inline four motor like the Zed’s will never have the same kind of earthy character as the Z900RS’s twin and three-cylinder rivals, but it makes up for it with apocalyptic exhaust raw on the throttle and a blood-spitting gurgle on the overrun. The Kawasaki Z900RS horsepower is 109bhp.

A big Zeds is as bulletproof as a tank and the attention to detail here borders on the obsessive. The Z900RS is more like a one-off special than a high volume production bike.

Kawasaki say they’re gunning for the similarly priced BMW R nineT Pure, but the Z900RS has to face a raft of retro rivals such as the Triumph Bonneville T100 and Yamaha XSR900.

With its impressive blend of performance and disco-cool Z1 style, it could easily beat the lot of them.

Equipment

4 out of 5 (4/5)

There’s a cacophony of Z1-inspired detail, from the ducktail back end and oval rear light, to the machined engine fins, textured metal tank and side panel badges, replica cam covers and clocks, which use the same typeface and needle shape (resting at the same angle at zero) as the originals.

Step back and you’ll see how the new upper frame shape allows the seat and slim, pear drop-shaped fuel tank (which extends down, behind the side panels) to be placed horizontally, like the ’72 machine and from above the Z900RS has the same slinky ‘hour-glass’ shape. The metallic brown and orange livery isn’t just a faithful replica of the original’s carcinogenic paint, it has one of those flawless, glistening finishes that looks like it’s still wet with lacquer.

Kawasaki have cleverly made crisp rear LED lights glow like a 70s light bulb, the orange tank stripe wraps around the front of the tank and meets around the front in a Z-shaped bow and the Euro-spec speedo on our test bike goes up to 240km/h, just like the original.

Everything from the Z900RS’s chest puffing riding position, to the view down to the wide chrome bars and the unholy growl it makes with a fist full of throttle, can’t help but make you feel good.

Modern day niceties like the multifunction display between the analogue dials, the easy to use switchgear, traction control and skin-saving ABS all give the Z900RS a safe, practical edge and as you’d expect there’s a raft of Kawasaki goodies available, too, from crash protection, to a bikini fairing, grab rails and heated grips.

There's a choice of three colour schemes on offer: metallic green, black, and grey.

It's a fantastic bike as is and won't disappoint. Clutch is very light for those who don't work out or are getting arthritic. For me i'd love it even more, if that's possible, if it had 30HP more but with same gearing characteristics - cross between it and Z1000SX (which I also have). I can see where Kawasaki came from with Z H2 but I prefer straight forward in line 4's and no supercharger. It's definitely a keeper. It's reminiscent of the best bits from the bikes of the 70's but wholehartedly improved in every way to produce the same big smiles in the best possible way.

Front brakes are good but like most other bikes back brake is made of wood.

I love it as is. Mid range is fantastic and the intake and exhaust noise make me sile every time. Although I am greedy and would still like 30BHP more. (as above comments).

Reliability & build quality 4 out of 5

Reliability - Had it 2 years now - finish is still good. Performance still good. done 3800 miles. Only a couple of events of false neutrals but may have been down to me being a little club footed, changing down at higher revs. Quality is outstanding but don't buy Kawasaki crash bungs - they are plastic, flimsy rubbish and won't protect anything!

Value vs rivals 4 out of 5

Don't believe £120-£140. That's for the 600 mile service! Servicing is always reasonable at first service but gets more expensive at each service so estimate £250-300 for say a 2 year service and although I love the original tyres - it handles just great & they've handled everything I've thrown at them with no probs they only last about 2500 miles so £250 per 2500 miles just for tyres too. so for medium complexity service and set of tyres per year that's realistically about £500-£600 and more when valve clearances get checked but it's worth it.

Equipment 5 out of 5

Only use traction control on gritty and / or wet roads. Love the analogue clocks. LCD / TFT Displays aren't for me. I love old school needles wizzing round and they're easier to see with peripheral vision so you keep eyes on road and they are sexier..

Buying experience: Test rode one from Preston Motorcycles and loved the confidence inspired handling round bends and roundabouts as well as the looks / sound. Made me smile so much I bought one and have not regretted it.Was going to order one for my birthday in January with quoted 20 wk lead time at that time however they had a cancelled order in the right colours so got it in two weeks (October). I would buy a second one new if I could afford it to keep for only sunny dry days.

Bike looks and sounds amazing. So much torque. Pulls in any gear. Even 6th. Glad it has a gear position indicator I always think it's in a lower gear !!!!

Traction control and abs work great. Fuel gauge not the most accurate. But you do figure it out !

Absolutely love my Zed in fact I will probably trade up again to the same model but a different colour. I no boy racer so understand it might be a bike for everyone but I recommend going for a test ride to see how good it is... I haven,t changed any of the standard settings or tyres as it is fine for me, plenty of power to play with with a great exhaust note. It’s fair to say my bike has only seen bright sunlight and never experienced the wet but as a man in his late fifties is there a better hobby.....

The clocks with the digital read out between the 2 looks brill. And for OEM tyres they top quality.

The worst thing about the bike is the standard tyres as the MCN review states. Great Facebook owners group, with lots of upgrading info for this bike is Z900RS UK. Easy to ride bike, great suspension, brilliant radial mounted brakes and looks to die for! 140mph top end and hits over 130 very quickly indeed, just as happy to cruise along at legal speeds though. Best looking motorcycle for sale in 2018 by far.

Really easy bike to just get on and ride, certainly fast enough for me, but not intimidating. Throttle initially feels a bit ‘snatchy’ but you quickly get used to it. First thing you notice about the RS is obviously the way it looks - I bought mine without seeing one ‘in the flesh’, the early on-line shots of it were enough to convince me, and I wasn’t disappointed. Brakes are pretty good, though not as sharp as I expected, suspension feels spot on, sharp and fully adjustable if you’re that way inclined. I previously owned Harley-Davidsons (and an early model Buell) before this, so let’s face it, the RS, to me at least, is a massive leap forward in performance and handling. The only negatives so far are having to put up with nonsense from blokes that owned Z1’s back in the day - no, it wouldn’t look better with twin shocks, a four into four and skinny spoked wheels. A small price to pay though, for owning what I consider to be a very accomplished and pretty motorcycle.

Brakes are good, though not as sharp as I expected. Think I’ve only felt the ABS kick in a couple of times so far. Ride quality felt great straight out of the showroom and I haven’t felt the need to tinker with it so far.

Engine 5 out of 5

Generally easy going, torquey with an even spread of power, get to about 6,000rpm and it goes like a stabbed rat!

Reliability & build quality 5 out of 5

I’ve only owned the bike for four months, and so far, no problems. At the end of the day, it’s a big Kawasaki four, and I think they’ve kind of got the hang of manufacturing them by now!

Value vs rivals 5 out of 5

Ten and a half grand on the road was about as much as I wanted to pay - I was initially thinking of getting the new Speed Triple, but thought it was just a bit more than I could afford. Yes, it’s more expensive than the other Japanese nakeds, but come on, just look at it!

Equipment 4 out of 5

It’s a naked bike, what do you need? Perfect for street riding, OEM tyres are a bit average.

Buying experience: Bought it from my local dealer (Autorama, Batley), paid about eleven grand (got the Kawasaki lower seat and a tail tidy fitted).
