January 2021 was a tumultuous time for biking as the chaos of Covid combined with the implantation of strict Euro5 emissions limits that proved to be a death sentence for several legendary bikes. Those regulations essentially wiped out the once-dominant 600cc supersports class in Europe: the CBR600RR, GSX-R600, YZF-R6 and ZX-6R all fell afoul of them and disappeared from sale.
Now the Kawasaki Ninja ZX-6R is back, revamped and reengineered to achieve Euro5 certification, allowing it to stand alone as the only option for riders who want slice of 600cc (well 636cc to be precise) four-cylinder action.
Those of us old enough to remember the days when 600cc fours ruled the sales charts will wince at the idea of a five-figure price tag, nobody needs to be reminded that inflation is a real thing – and actually the £10,599 rrp that the new ZX-6R carries could be seen as something of a bargain.
For comparison, the old model cost £9699 way back in 2019, and a scan of the classifieds shows dealers are asking close to £10k for low-mileage used examples. There’s no other road-legal, four-cylinder, Japanese supersport-class bike on the market, but track-targeted Yamaha R6 Race costs £12,900 and the more focussed R6 GYTR is £17,800.
You’ll have to wait a little while before getting a ZX-6R, though, as the bikes won’t be reaching UK dealers until October this year.
Meeting the new emissions laws means a sacrifice in peak power for the ZX-6R, with a maximum of 122hp (91kW), although the firm says that rises to 127.7hp (95.2kW) at speed with the aid of ram-air.
The previous model was good for 95.4kW (128bhp) without ram-air assistance, and even that was a slight decline on the 96.4kW (129.3bhp) that the 2013-2018 version of the ZX-6R managed. It’s all down to emissions limits, of course – current Euro regs are particularly tough on high-revving, small capacity engines.
The power drop is reflected by a decrease in peak revs, with the 2024 peak arriving at 13,000rpm while previous ZX-6R’s span to 13,500rpm for their maximums. For 2024, there’s a new exhaust header, collector and silencer, plus revised cam profiles and reworked inlet funnels, all pursuing improved emissions performance and boosting mid-range grunt at the expense of top end power.
As before, there’s a choice of power modes, a quickshifter and a traction control system, but there’s no IMU so the ZX-6R doesn’t feature the latest in cornering traction control. A new dash, with a 4.3in colour TFT screen, controls those riding modes and gives smartphone connectivity to the 2024 model.
Like the last generation, the 2024 sits on 41mm Showa SFF-BP forks and a Uni-Trak rear end with a gas-charged monoshock. Both ends are fully adjustable for rebound, compression and preload, and the wheels are carry-overs from before, with 120/70 front and 180/55 rear tyres on 17-inch rims. For 2024, those tyres are Pirelli Diablo Rosso IVs.
Weight rises a fraction for the new bike. The old ABS-equipped model clocked in at 194kg, while the new 2024 version – with ABS as standard, required by law – comes in at 198kg ready to ride.
A new fairing is a key change for the 2024 ZX-6R, incorporating useful upgrades including full LED lighting and what Kawasaki calls ‘hybrid projector/reflector headlights.’
Although the side-on profile and riding position are largely unchanged from the old model – the seat, tank and tail are carry-over parts, as is the main chassis and suspension – the redesigned nose features cut-outs in the windscreen, claimed to reduce buffeting.
At the moment, there’s no claim for the ZX-6R’s fuel economy, but we’ll update when the figures become available.
The four-pot Nissin calipers are carry-overs from the previous generation, so braking performance isn’t likely to have changed, but the old model’s petal-style discs are replaced with more conventional, round 310mm units for 2024, reflecting similar updates to the larger ZX-10R. ABS is standard in the UK, of course, although some markets, like the USA, will be offered a non-ABS version that’s 2kg lighter and a fraction cheaper.
The decimation of the supersports 600 class over the last few years means direct competition for the 2024 ZX-6R is thin on the ground. While Honda has launched a new CBR600RR elsewhere, it’s not offered for sale in Europe, and the old Suzuki and Yamaha rivals are also unavailable here under Euro 5 rules.
MV Agusta F3 Rosso (RR shown) | Price: £14,840
With 798cc and nearly 150hp the cheapest version of the MV F3 is a class above the ZX-6R and priced accordingly.
Power/Torque: 147bhp/65lb-ft | Weight: 173kg (dry)
Ducati Supersport 950 | Price: £14,095
Another pricy option, the Supersport is more of an all-rounder than the ZX-6R, but with less performance on tap.
Power/Torque: 110bhp/68.6lb-ft | Weight: 184kg (dry)
Honda CBR650R | Price: £8,499
At the other end of the pricing scale, the CBR650R is one of the few four-cylinder Japanese bikes left in this capacity class, but it’s much less powerful and focussed than the ZX-6R
