With its genuine 163mph top speed, six-piston brakes, low’ish insurance group and evil induction noise the Kawasaki ZX-6R G-series is the bike that overnight made the 750cc superbikes look superfluous.

Even today it’s still considered a capable performer, though the suspension and stoppers will doubtless welcome a fettle.

If the Kawasaki ZX-6R's motor begs to be caned, then the chassis begs you to use it. It’s sporty yet comfy, precise but not flighty and roomy but not baggy. It’s a brilliant blend of real world practicality and trackside intent. The six-piston brakes aren’t as harsh as the older ZX-6R’s fours and can be improved with pads for the ZX-9R. The suspension and brakes will need refreshing by now to get the best from the package. Budget on around £200-£300 to do the job properly.

The Kawasaki ZX-6R's DOHC in-line four sounds better with each passing degree of the tacho’s sweep – all the way up to its glorious 14,000rpm redline – as the twin ram-air tubes resonate with the cold fury of quickly shovelled speed. It’s based on the older F-series engine, albeit with revised cams and new 36mm carbs. Carbs that, just like old one, suffer from icing on cold, damp mornings. Pass the Silkolene ProFST, Cyril.

The Kawasaki ZX-6R's finish is good, but ride your ZX-6R through a winter or keep it outside and it quickly palls with corrosion setting in around the shock if you don’t add a hugger. Electrics can suffer, too, so be generous with the WD40. 1998: Supersedes the ZX-6R F-series. Gains cartridge forks, semi-downdraught carbs and revised frame and motor. 2000: G-series superseded by J-series ZX-6R (new singarm, revised shock, engine and gearbox improvements).

These days there is so much metal to choose from that an aging 600 might not seem like the ideal candidate for your cash. But the G-series Kawasaki ZX-6Rs are still handsome performers providing you overhaul the critical areas of suspension and brakes. Find a Kawasaki ZX-6R for sale.

3 out of 5 (3/5)

With the Kawasaki ZX-6R you don’t get a hugger or centrestand. You do get a pillion seat that’s not a dirty joke, and a digital display for water temp, trips and clock, though.

I bought one for a track bike, it cost less than dropping my Ducati.After doing track days on it I am more than impressed, although tracks with long straits are frustrating if you hit the limiter in top half way along the main straight.

Good handling, stable but quick steering. Catch up to big bikes into and through corners.

Engine 5 out of 5

Lovely, free revving unit. No real power band, just building revs…

I can’t really comment, it has been converted to a track bike with aftermarket fairings and instrument cluster.

5 out of 5 Great, affordable old skool sports bike with a bit of attitude
26 October 2022 by Bolt

Version: G1

Year: 1998

The best thing about this bike is the how it is all old skool, the looks with it's 90's paint job, carbs, analouge clocks, comfy semi sporty riding position with lots of room and a decent enough seat for a pillion and no electronic fancy riding gadgets so it's all down to you and your bike control. I sit on it and just wish they would make modern bikes with these looks and ergonomics.Still quite quick for an old 600 and will put a smile on your face when you open the throttle far enough and as others have said the induction noice and roar from the standard exhaust when on full chat sounds great. What attracted me to the 6R was that to me it had a bit more edge to it than a CBR or thundercat of the same age, even if overall the cbr might be a better bike the 6R seemed to have more soul.Worst thing is trying to get genuine Kawasaki parts, most service stuff not an issue but alot of items dicountinued now or expensive so you have to go pattern, eBay or refurbed.

Ride quality & brakes 5 out of 5

5 out of 5 now but first thing I did was swap out the 6 pots for refurbished as new 4 pots, new discs and pads and braided lines and now stops really well and inspires more confidence. When I first got it it had the original 6 pots and discs, the calipers had new pistons and seals but the setup was useless and dangerous but was also old and worn out so fair enough, probably good in their day though.Suspension has been fine even though the rear shock looks to be original the ride has been fine for normal riding solo and two up on some pretty terrible UK roads although plan to change rear shock with the same but off a very low milage bike and refresh the front too whilst at it so it's nice and fresh for the next season.You probably couldn't push it like a new bike but then I wouldn't anyway, happy to cruise and enjoy the noise and the nostalgia.

Engine 5 out of 5

Engine seems very sweet no smoke or rattles and very smooth liniar power delivery, easy to handle and still with enough accleration and top end rush to satify most normal people. Easy to see why these were so popular back in the day and still need to have some restraint and respect as its no slouch when you get in the higher revs.

Reliability & build quality 4 out of 5

Bought without service history but got it quite cheap but realised soon after there would need to be a few things sorted. Once it had a basic engine service and carb strip and clean it's been really good so far and done plenty of happy trouble free miles over the summer.Can run quite hot on a really hot day but fan kicks in and normal temp resumes, prefers the open road to town traffic. Usually starts on the second or third click of the starter. Starting from when hot on occassion a slight issue although I suspect may improve with a valve check.Approaching 40k miles now and it looks pretty fresh but I have cleaned it up a bit and tried to take good care of it but if used as a daily I think it wouldn't look so nice but then you can have another bike for that!

Value vs rivals 5 out of 5

Not sure yet but in theory not too bad, tyres are expensive these days and rear is about £200, the rest similar to what you'd pay for any other older 600 I think. You need to find a mechanic that is happy and experienced enough to work on an older carbed bike though.

Equipment 5 out of 5

Basic but how I like my bikes to be. Would have been nice to have a fuel gauge and an easier to operate on the move fuel tap.People have mentioned the clocks hard to read I have found them fine and like the look of them. Underseat (pillion) storage is pretty useful can get a decent size lock and chain in there or my lunch but not both.

Buying experience: Bought privately for £1600 probably a few hundred too much in retrospect. Next time I would spend longer looking as there are plenty still out there and get one that's already well fettled and looked after as you can easily add a good few hundred for new discs and pads onto the price and they are often in bad shape, basically pay as much as you can afford and be picky if you want a nice one.

Cracking bike that does it all. Commute, tour and trackdays. Awesome value for money. No computers, modes or any other modern gadgets. The most tech advanced bit is probably the digital clock / odometer! And it has carbs and a fuel tap. (No fuel lights on the dash). I just love the 20th century innocence of this bike.

Ride quality & brakes 4 out of 5

Ride quality is good considering - the new rear shock has transformed it. Brakes are very 20th century, but still do the job. (They are definitely lower league compared to modern Brembo's) . Brakes need rebuilding every 2 or 3 years. Strip, clean, new seals, new fluid, new pads.

Engine 5 out of 5

Awesome bit of kit. Responsive from low down. Just as happy bimbling at 4000 revs or giving it the berries on the red line. Mine uses a bit of oil these days - just check the level regularly.

Reliability & build quality 4 out of 5

It's not a Honda - however mine has faired quite well. It has been garaged throughout it's life, although it has seen a lot of rain in the last 23 years. Reg /rec failed after about 12 years, I've done a few fork seals, refurbed the brakes several times, changed the stem seals, and renewed the rear shock. I've got 35k on the clock and this bike has used as designed. I'm happy with reliability.

Value vs rivals 5 out of 5

I do mine own, change brake fluid every 2 years, oil & filter every 2 years and fork oil when I need to do a fork seal. (Might as well do the oil in both forks when you have stripped the front end anyway)

Equipment 5 out of 5

I have given this 5 out 5 for equipment because it doesn't have computers, modes or anything unnecessary. It has all the essentials. Currently running michelins - I've never had a bad tyre, and usually see what is on offer when I need new.

Buying experience: Bought new from Motorcycle City in 1999. (They went bust ages ago and to be honest I wouldn't recommend them if they were still about.) I paid £6495 OTR with 4 years 0% finance. (Which is why I used Motorcycle City). Once you have signed on the dotted line, they don't want to know you. (And the PDI was rubbish)

Abit hard seat and wrists on longer rides (1500km) but had 6000km with few stops but that was realy painfull In the end. Love the brakes and responds well.

Gives a good boost about 8000rpm but all over it's great fun.

Took 12 years for fuel pump to brake down and leak but otherwise nothing of greater importance.

Set it up for ur needs and except it's an older bike and it's just fine

Engine 5 out of 5

Perfect, it has no power band, zero, it just pulls from 0-......., great for any sort of riding, lovely and well designed, my last bike was a 2000 srad and that was powerless till the power band then yeehaaa, great but no the best to live with all the time, the srad is faster, more nimble but is less comfy, less miles per tank, the ninja is no slouch it's just more everyday.

We'll build and reliable if it's been cared for.

This is my first 600 (moved up from a geared 50 :P) and it really is a brilliant machine, the only downsides are that I'm 6ft so it can get abit wristy and the fact that it doesn't have a fuel light. Other than that this is a truley awsome bike!

I am very proud to be riding this bike, yeah its the biggest i've ridden, but what a bike i love it. the sound from my scorpion can through the k&n is awesome, very addictive. I covered 800 miles when i bought it few weeks ago in a week and enjoyed it all, i've never felt so confident in the wet and the power in all gears is soo useable, it goes faster than the figures say too, the 3 pot brakes are awesome too and the bike is soo comfy compared to any other sports bike i've rode, go by one i got mine from dealer with extras and a warranty with 11k on the clock and 2 new tyres for ....wait for it 2 grand. the best 2 grand i ever spent, and no the green ones not faster lol

5 out of 5 Fabulous bike! Buy one!
21 April 2006 by burncpt

Sorry to all of you that think Kwaks are only green, the Black/Gunmetal G1 is the best! Went like stink, the engine is unbelievable after bandits and the like, and the airbox howl makes it seem 20mph faster, especially with a micron can. Build quality seems good, after 7 years my G1 is mint, not even a hint of corrosion. Riding position is ace for tall riders, had to ride an SV650 for a month after being knocked off it and hated every minute in comparison. Screen is great, mirrors steady and clear, the whole bike screams quality. Will never buy anything except Kawasaki again! Strengths: Engine, looks (NOT green!) Ride quality, Build, Sound (oh yes!). Weaknesses: You will be devastated if you crash it! Seat wobbles(!) Crappy stiff fuel tap, hard to find an un-bodged original one.

This was my 1st big bike,i t is a cracking bike for a 1st timer. It is comfy enough for short or longer distance riding, not to painful on the wrists. Riding position is user friendly not over stretched & this is from a 5ft 9inch bloke. Get it to 9000rpm & it is instant grin factor. Strengths: Changed from Bridgestone 010's what it came with over to the 020's. These are a little more hard wearing, but still gives loads of feel. Weaknesses: None for the bike, only me because I can't get the best from it.

5 out of 5 Almost perfect
30 August 2004 by DAZZX6R

This bike has taken everything in its stride. Almost 40000 miles in five years with no major problems. Everything from daily commutes to European tours. Its still great to look at, still puts a huge grin on my face, and still comfy for 400 miles in a day. What more could you ask for? Just the noise it makes at high revs is enough to make anyone laugh and grin like an idiot. Strengths: Engine, noise, comfort, easy handling, brakes, 180 miles from a tank, reliability...... Weaknesses: Expensive when you drop it. Could do with a bit more power now I'm used to it. (An extra 36cc might sort it...).

I have a 99 G2 model and only planned to keep it for 2 years. I'm on my 4th year and still plan on keeping it for at least another 2. I just love it's mix of raw power, easy handling and still good looks and comfort. It is used every single day for commuting and 3-4 trackdays in the fast group too. It takes it all in it's stride superbly. Reliable and economical too! Just love it. Strengths: Performance. Steering. Brakes ( after hoses and pad change ). Economy. Comfort. Weaknesses: On 3rd set of fork seals and 2nd set of brake discs.

When I was looking for a sports 600, it was between the GSXR and the ZXR, The ZXR won on looks, and I'm glad I went for it, I like the riding position and power delivery, the induction niose on this bike is something else, the engine appears to be unbustable, finish isn't Honda quality, but its stood up well to all year round riding. Strengths: Looks, Engine. Weaknesses: Carb icing, Dunlops.
