Suzuki GSX1300R Hayabusa Gen 3 (2021+) Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Suzuki Hayabusa Gen 3. It’s also known as the Suzuki GSX1300R or just the Gen 3 ‘Busa to its loyal fans.

The 3rd gen Suzuki Hayabusa continues in the same vein as the original two models, with history back to 1999. The Hayabusa is still a big, high-power sportbike, with a focus on top-end speed and stability without sacrificing too much in the way of sporty handling.

The 3rd gen Hayabusa is a big technological improvement over the Suzuki Hayabusa Gen 2, which was made between 2008 and 2020 (with ABS and Brembo brakes from 2013), the Gen 3 gaining a redesigned chassis, intake/exhaust, engine tune, and a host of rider electronics including cornering ABS/traction control, cruise control, and even a speed limiter.

But the Gen 3 Hayabusa is still based around a 1340cc inline four-cylinder engine with dual overhead cams and four valves per cylinder.

What you need to service your Suzuki Hayabusa Gen 3

Hayabusa owners are passionate motorcycle owners, and this includes owners of the Gen 3 Busa. Many do their own service and become experts at removing all those fairings!

Here is what you need to service your Suzuki Hayabusa Gen 3. Most are still within warranty, but it’s good to know for later (or if you don’t have a mechanic nearby).

PartSuzuki Hayabusa Gen 3 spec
OilSuzuki specifies engine oil with JASO MA spec, or at least API SF/SG or SH/SJ spec, e.g. Motul 7100 10W-40.
Oil filterUse a Hiflofiltro HF138RC, which is a drop-in high-quality replacement that can be installed with a regular wrench. This is the same as for the Gen 2 (and many other Suzuki bikes).
Air filterYou can use a DNA high-performance air filter with part code P-S13S21-0R.
Spark plugsThe standard spark plug for the Gen 3 Busa is NGK CR9EIA-9 per the manual.
Brake fluid/Clutch fluidSuzuki (like most motorcycles) requires DOT 4 brake and clutch fluid, e.g. Castrol DOT 4.
Front Brake padsMany agree that EBC brake pads give better bite and less fade. The Gen 3 Hayabusa’s Brembo Stylema calipers take FA447HH pads.
Rear brake padsGet the corresponding rear brake pads FA419HH.
CoolantSuzuki only requires a coolant that’s “compatible with an aluminium radiator”, preferring “Suzuki Super Long Life Coolant“. A good alternative is Motorex M3.0.
Chain maintenanceUse either Motul chain paste or a complete Motul chain care kit for frequent chain servicing.
GreaseAlways handy to have some lithium soap-based grease for external pivot points, like the kickstand.

Suzuki Hayabusa Gen 3 (2021+) Maintenance Schedule

Below is the maintenance schedule for the Suzuki Hayabusa Gen 3 (2021+).

Note: This schedule is adapted from the Gen 2 manual and the 2021 Suzuki GSX-R1000 manual. I’m still waiting for a confirmed Gen 3 manual, but Suzuki maintenance schedules are the same for liquid-cooled four-cylinder motorcycles.

Also, the manual suggests you inspect the fuel hoses, and replace coolant on a different schedule depending on what kind you have (blue vs green).


  • The service interval should be judged by number of months or odometer reading, whichever comes first.
  • At the end of the service schedule (beyond 14500 miles or 24000 km), follow the schedule in the pattern shown, every 1-4 service intervals.
  • The break-in schedule is omitted. It is essentially an oil/filter change and a check for leaks and torques.
  • I= Inspect and clean, adjust, replace or lubricate as necessary.
  • R= Replace
  • T= Tighten

Tire size and tyre pressure for the Suzuki Hayabusa Gen 3

The following tire size and pressures are specified in the manual. The stock tyres are Bridgestone Battlax Hypersport S22 tires, which are high-perforamnce sport units that few would fault for general purpose use.

Of course, use whatever tires you prefer adjust pressure as suits your riding style.

TyreSizeTyre pressure (cold)
Front120/70 ZR17 58W250 kPa / 2.50 bar, 36 psi
Rear190/50ZR17 73W290 kPa / 2.90 bar / 42 psi
Tyres and tyre pressures

These are the pressures in the manual. For single-person, sporty riding, many Hayabusa riders prefer lower pressure in the back tyre — an even pressure of 250 kPa or 36 psi is common.

About the Suzuki Hayabusa Gen 3 (2021+)

The Suzuki GSX1300R Hayabusa is a hypersport motorcycle series made by Suzuki since 1999.

When Suzuki released the first Hayabusa, it took the motorcycling world by storm. It was announced as the fastest production motorcycle, and testing proved this — it quickly took the crown from the Honda CBR1100XX Super Blackbird, which was had briefly held the title.

Since then, the Hayabusa (and its descendants) have been known as high-speed motorcycles, that are supposedly speed-limited to 300 km/h but which frequently are derestricted to exceed this absurdly high limit.

But the Hayabusa is much more than a high-speed machine. It’s a comfortably heavy sportbike that you sit in rather than on, a capable tourer, and a decent handler considering its extra weight over a literbike such as the Suzuki GSX-R1000.

So besides its speed, the Hayabusa is well loved for its all-round performance. It has a very loyal community of followers who love it for its handling, comfort, style, reliability, and all-round prowess.

What’s unique about the Suzuki Hayabusa’s big engine is that while it’s relentless up top, it’s very easy to manage down low — even at around-town or parking lot speeds. This was true of the Gen 2, and it’s even more true with the Gen 3 — an experience of even more smoothness.

As with the Gen 2, the engine powering the Gen 3 Suzuki Hayabusa is a 1340cc liquid-cooled dual overhead-cam block. Controversially, on paper it makes slightly less peak power than the Gen 2s motor, with of 140 kW (187 hp) at 9500 rpm — a drop of 7 kW (10 hp).

But in testing, the Gen 3 often beats the stock Gen 2 on a quarter miles because of the way the Gen 3 makes power, with a much meatier midrange, and because of the rider aids in getting power to the ground, including traction control and wheelie control, courtesy of the six-axis IMU that also gives the bike cornering ABS>

Of course, peak power and stock performance are somewhat meaningless as most Hayabusa owners modify their bikes, and the same is true of the Gen 3. There are already a host of aftermarket options available for exhausts and tunes, many of which can take the big birds to 200 hp at the wheel with relative ease.

The suspension on the Gen 3 Hayabusa is by KYB. It’s top grade, with fully adjustable (preload, compression damping, and rebound damping) units front and rear. The fork on the Gen 3 have diamond-like coating (DLC) for more durability as well as responsiveness. The internals of the rear KYB shock have also been revised since the gen 2.

The braking is also impressive, with Brembo monoblock calipers up front. On the Gen 2 they were Brembo 4-piston units, and on the Gen 3 they’re Brembo Stylema calipers — skipping the intermediary generation of Brembo M50s. Suzuki also increased the brake disc diameter from 310 to 320mm.

The Suzuki Hayabusa Gen 3 is still not a lightweight motorcycle. It weighs 264 kg wet — roughly a full third more than most liter-class superbikes that make more power these days. So clearly, if you’re looking for the ultimate in power-to-weight, then you should be looking at an L7 Suzuki GSX-R1000.

Manual for the Suzuki Hayabusa Gen 3 (2021+)

The above maintenance schedule is derived from the service schedules for modern 4-cylinder liquid-cooled motorcycles from Suzuki, which all share an identical schedule, though differing in part spec.
