Bigger, better 'Busa: Suzuki Hayabusa replacement on the way

1 of 2

This new artist’s impression based on the latest information out of Japan gives the clearest indication yet of Suzuki’s hugely-anticipated new Hayabusa, due to be officially unveiled later this autumn.

Rumours have been swirling since early 2018 when the Concept GSX started appearing, but the previous version of the bike eventually went extinct with no successor at the end of that year.

Then in February 2020, Suzuki patent drawings gave us new hope that an updated version of the original 200mph bike was on the way. And now this render gives us our best idea so far what we can expect from an even bigger ‘Busa.

This bike is the overdue replacement for the second generation, 1340cc GSX1300R Hayabusa, introduced in 2007 then updated with Brembo Monobloc brake calipers and ABS five year later and discontinued as emissions laws tightened.

In order to pass muster for Euro5 without losing any of its legendary hyper bike status, the new ‘Busa will have a higher capacity of around 1440cc as well as revised intake and exhaust; we expect it to produce around 197bhp.

To keep all those horses in check, the new bike will likely use the S.I.R.S (Suzuki Intelligent Ride System) implemented on the 2020 V-Strom 1050 XT. This could mean lean-sensitive ABS controlled by a new IMU, multiple rider modes, hill-hold control and cruise control, all operated through a new TFT dash.

The bike is not a complete clean sheet and features like the familiar massive aluminium twin spar frame is expected to be retained, but it will be updated, along with the adoption of the latest Kayaba suspension front and rear.

The new ‘Busa is expected to be unveiled later this autumn before going on sale in Spring 2021.


Return of a legend: new Hayabusa spied in Suzuki patent leaks

Suzuki GSX concept model

For more than a year now it’s been impossible to buy a brand new Suzuki Hayabusa in Europe after the legendary hyperbike failed to meet Euro4 emissions limits – but it’s not gone forever. Suzuki engineers are hard at work on a completely revamped version.

In recent months several Suzuki patent applications have hinted at the next- gen Hayabusa’s looks and technology. It’s clear the new bike isn’t a completely clean-sheet design. The engine’s overall layout and many castings appear to survive, helping reduce development costs and providing a link to the original.

Normally-reliable sources in Japan say capacity will be hiked to around 1440cc, a route several manufacturers have recently taken in an effort to meet tougher emissions laws without losing performance. Power is likely to remain around 200hp but the extra cubes will bring an increase in torque and rideability.

Among the new patents are emissions-specific elements including a carbon canister to filter evaporating fuel fumes and another for a redesigned exhaust with enlarged collector box where two catalytic converters hide.

We can also see a new frame with slimmer main beams than the current bike. This also loses the cast-alloy extensions below the rider’s seat, instead having a conventional bolt-on subframe.

Where top speed was the original ’Busa’s main goal, modern 1000cc superbikes have caught up so Suzuki will emphasize the bike’s relative comfort and ability to swallow huge distances with minimal effort. A semi-automatic gearbox is key to that change.

It’s still based on the old six-speeder but, with electronic actuators to shift cogs and manipulate the clutch at the prod of a button, it’s not unlike Yamaha’s FJR1300A.

If all goes to plan we expect see the bike towards the end of 2020 as a 2021 model with styling likely to be similar to the ‘Concept GSX’ mock-up that was shown at the 2015 Tokyo Motor Show. Keep an eye on MCN for more as we get it.


Last two unregistered Suzuki Hayabusa models hit showrooms

Suzuki Hayabusa on the road

There are just two unregistered new Suzuki Hayabusas left in the UK – the last bikes available before the model becomes extinct at the end of the year, one of the last casualties of Euro4 rules.

Rumours and hints persist that Suzuki will release a successor, having teased us with the Concept GSX on more than a few occasions over the last couple of years – but it won’t arrive in 2019, and factory sources say it looks unlikely that we’ll see in in 2020, too.

The firm’s legendary GSX-R750 and GSX-R600 are also now completely sold-out in the UK, and there’s nothing in Suzuki’s 2019 line-up to replace either of them – with no hint whatsoever that there are new versions in development for 2020 or beyond.

Suzuki dealers will be pinning a lot of hope on shifting new Katanas by the truck-load in 2019.


Suzuki quietly working on a new Busa

First published on 27 February, 2018 by Jordan Gibbons

Suzuki Concept GSX

If you look at Suzuki’s line up of bikes for 2018, you would be forgiven for saying they’re having a fallow year. With the exception of colour changes, the SV650X is their only real new bike and that’s just a dress up kit for the venerable twin. Back in Japan however, Suzuki engineers have been quietly working away on the next Hayabusa and new patents show a huge leap forward.

Slick shiftin’

Suzuki have been dropping big hints about the Hayabusa’s replacement for some years. Last updated in 2008, the bike’s fallen behind its sports-tourer rivals and production for Europe has had to cease.

But now a new patent has emerged for a semi-automatic gearbox, suggesting Suzuki may take the Busa in an interesting new direction.

The patent, which was released last week, shows an external semi- automatic gearshift mechanism bolted to the outside of a Hayabusa.

The mechanism in the patent uses an external sensor on the gear lever working in tandem with a servo to acuate the clutch, alongside another actuator to do the shifting.

Unlike the DCT gearbox found on Hondas, this system is fitted externally and doesn’t require any changes to the innards of the engine. This means it could be an optional extra on new models, or could perhaps even be retrofitted by dealers.

Launch control

With the advent of quickshifters and autoblippers, you might be wondering what advantages this system offers. Looking at the patent, there seems no reason that it couldn’t operate in fully-automatic mode, which is where things get really interesting. Launch control isn’t impossible, so that when you pin the throttle from a standing start, a computer times each gearshift for maximum acceleration and power without any risk of missed shifts. Even if you have no intention of taking the bike to the strip, it’s could give the potential to blow away the competition when firing off from the lights.

The semi-automatic gearbox isn’t the only update we’re expecting for the Hayabusa but there’s still a lot
of debate about what will hap-
pen to the engine. It’s assumed
that it will grow to around 1400cc but to keep the power up (and in line with new emissions laws), it’s also assumed that it will be turbo-charged. Suzuki will be looking to steal the show from the other superbikes, so we’re expecting a genuine 200bhp in stock trim.

It’s also expected that the new Hayabusa will get the more comprehensive electronics packages fitted to cur- rent superbikes such as a ride-by- wire throttle with rider modes, IMU-based traction control, anti-wheelie and cornering ABS. It will likely gain other modern tech such as a cruise control, a TFT-dash and smart phone connectivity.

The general design of the
bike is sure to get looked
at too. The current model’s aerodynamics date back to the late 1990s but
you only have to look at MotoGP bikes or the Kawasaki H2 to see that aerodynamics are about stability as well as speed. We’re expecting the new bike to change radically, without losing the essence of the design or putting off cur- rent owners.

  

Time’s up

The current Busa doesn’t meet the Euro4 standards, so Suzuki have been selling the bike under derogation rules. Unfortunately, the grace period ends in January 2019, which means Suzuki will have to stop selling it. Even with that added time pressure, we’re not expecting the new Hayabusa to be unveiled until the 2019 Tokyo show. It will likely then go on sale in 2020, just in time for the new Euro5 standards. Until then, you’ll have to get your loopy speed fixes elsewhere.

What will the Hayabusa need to succeed?

A sportier character

To be competitive against the likes of Kawasaki’s H2SX it will need to be shorter and lighter. Suzuki now offer two levels of GSX-R1000, so both sporty and touring versions of the Busa make sense.

More power

With the likes of Kawasaki’s H2 making over 200bhp at the back wheel, Suzuki will have to find 30bhp. It’ll likely inherit the variable valve timing from the GSX-R1000 and forced induction could
be the key – as shown by their turbo Recursion concept.

Proper electronics

Suzuki won’t have developed their IMU and control systems for just the GSX-R1000, so expect the kit on the new Busa. Expect all the usual rider aids, the option of a push-button gearbox, launch control plus semi-active suspension.

Better brakes

The Hayabusa’s bugbear, thanks to old technology. Expect Suzuki to carry on their Brembo relationship, combined with cutting-edge cornering ABS, such as on the GSX-R1000. A key to better braking performance will come from superior weight distribution.

GSX-R600 dead?

Both the GSX-R600 and the R750 face the same problem that the Hayabusa does – they’re not Euro4 approved and face the same January 2019 deadline. Unfortunately for supersports lovers, the outlook is not good.

Amid poor sales and a stagnant market for smaller capacity bikes, we’re led
to believe that the 600 will disappear from the range
and not be replaced. Sources suggest that the 750 may well get a reprieve, especially if Triumph release a Daytona
765 and help reinvigorate the segment, however it’s very much up in the air. So don’t hold your breath, basically.
