Suzuki seeks 1440cc Hayabusa patent

Suzuki Hayabusa 1440cc

It’s almost news too good to be true, but it seems Suzuki Motorcycles has filed for a patent for a new Hayabusa engine with 1440cc of tarmac-tearing oomph!

The former world’s fastest motorcycle is now in wind-down mode as it no longer meets the tough new Euro5 emissions regulations coming next year.

While some will still be made for the Australian and US market, the future of the bike depends on developing a new, cleaner engine.

There has been speculation for some time that Suzi would make a bigger donk.

According to Bennetts of the UK, it will have a 1440cc engine which is 100cc more than the 148kW outgoing model.

They also say it will have a slimmer design, double exhausts like the current model and an evaporative emissions control system.Suzuki Hayabusa 1440cc

Third patent

It is no longer just rumour that the Hayabusa will be retained as this is the third patent for an upgrade.

The ageing Hayabusa has only had two major upgrades in its 17-year history.

While many are expecting turbo or supercharger technology, the first two patents were for a semi-automatic transmission.

The first patent in February 2018 detailed how actuators would be used to control clutch engagement and the shifting of gears.

So it’s not totally automatic as riders would still need to change gears but without the need to use a clutch.

While the patent application used a drawing of a Hayabusa, it was not necessarily meant for that bike.

However, the second patent described the gear position sensor, confirming that it was destined for the Hayabusa.

The rest of the drawings show the bike much as it is now.

Suzuki president Toshihiro Suzuki has confirmed that Suzuki engineers are working on the new bike, but has not said when it would be due.

He says it will follow the same style, but gain several electronic riding aids.

There is not much they can do with the styling as the bike was designed to be aerodynamically stable at high speeds.

It was apparently designed on paper by aerodynamic experts, but not tested in a wind tunnel until several years later when it was confirmed the aero theories actually worked.

So when it was updated in 2008 and 2017, there was no need to change the shape.

  1. If the new haybusa is 1440 with electronic devises. Would be brilliant. It should put the hayabusa at the top of the tree. There is nothing greater than riding a big bore bike. And nobody does it better than a Suzuki hayabusa.

  2. I’ve owned both the series 1&2 busas, upping it to 1440 will put it in the same cc field as the kwaka zx14 but Suzuki will no doubt keep its aerodynamic style as the zx14 is a brick wall Suzuki will regain top spot again as the ex fastest but with 2020 technology, can’t wait to see it,ride it !

  3. I don’t care as long as big arse road tearing manual motorbikes are produced,because one day it might be all stopped,all we will have is memories

  4. Regarding no power adder from the factory, it’s better to add the power yourself and leave the manufacturer free from liability so they can continue to produce the modular design that lends itself so well to modification. Giving us a 100cc bump in our starting place, this is huge. As long as we can still add a spacer under the cylinders the potential us there for all the power you could use, with the potential for a 1200HP Dyno Queen.

  5. Couldn’t careless… NO TURBO.. NO SUPERCHARGER.. If i was going to spend the money id Just buy a H2.. I love Suzuki but this is just a joke now!!!!

    1. The H2 is just a pig ugly overpriced answer to a question that wasn’t asked. Turbo’s and superchargers are just unnecessary on a motorcycle, as was learnt in the 1980’s.
