Suzuki B-King GSX1300BK (2007-2012) Maintenance Schedule and Service Intervals

Blue 2007 Suzuki B-King

This is the maintenance schedule and service intervals for the Suzuki B-King, the big muscle standard made between 2007-2012. It was also known as the GSX1300BK.

The Suzuki B-King was based on the Gen 2 Suzuki GSX1300R Hayabusa, but in a standard bike configuration, and with some differences to both the intake and exhaust. Thus, the engine is the same 1340cc liquid-cooled inline-four cylinder engine, pushing through a butter-smooth six-speed transmission and chain drive.

The B-King was retired after 2012, with Suzuki focusing on the Bandit 1250 as its big-bore standard.

What you need to service your Suzuki B-King

B-King owners are passionate motorcycle owners who modify their bikes and push them beyond their already-capable limits. Many do their own service, too.

Here is what you need to service your Suzuki B-King. The parts list is quite similar to that for the Hayabusa, though the brake specs and air filter are different.

PartSuzuki B-King Spec
OilSuzuki requires 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.
Air filterUse a K&N air filter as a drop-in replacement, part number SU-1348.
Spark plugsThe standard spark plug is NGK CR9EIA-9.
Brake fluid/Clutch fluidSuzuki (like most motorcycles) requires DOT 4 brake and clutch fluid, e.g. Castrol DOT 4.
Front Brake padsAsking what are the best brake pads is a popular forum discussion point! But many agree that EBC brake pads give better bite and less fade. Front pads code is FA347HH.
Rear brake padsGet the corresponding EBC rear brake pads FA419HH.
CoolantSuzuki only requires a coolant that’s “compatible with an aluminium radiator”. Most motorcycle coolants are, and so a Valvoline Asian Vehicle Coolant is a fine option. You can also get Suzuki Super Long Life Coolant from dealers, or an alternative.
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 B-King Maintenance Schedule

Below is the maintenance schedule for the Suzuki B-King. It’s from the manual, adapted slightly to fit a web page.


  • I = Inspect and clean, adjust, replace or lubricate as necessary.
  • R = Replace
  • T = Tighten
  • Interval: This interval should be judged by number of months or odometer reading, whichever comes first.
  • The break-in service is omitted as these bikes are long broken-in.

About the Suzuki B-King

The Suzuki B-King is quite a unique motorcycle in modern motorcycling history. It has an extremely powerful engine, only slightly detuned from the Hayabusa superbike it otherwise powers, and has the same gearing. So this is a naked bike with quite long legs!

The only modern parallels to the Suzuki B-King are bikes like the Kawasaki Ninja Z H2, the supercharged naked bike from Kawasaki. While Suzuki still makes the Hayabusa, they stopped making the B-King a long time ago.

The core of the B-King is, of course, the 1340cc Hayabusa inline-four, a DOHC 16-valve liquid-cooled engine. What’s beautiful about the Hayabusa engine is that it’s already torque-forward — it was never a bike that people scream past 14000 rpm, like one would with a literbike engine. Thus, the power curve suits street riding — to a degree.

Suzuki still did some retuning of the engine, modifying both the intake and the exhaust. The power curves are quite similar, according to Cycle World’s testing, though the Hayabusa has more pull at the upper end of the power curve.

Suzuki limits top-end power by cutting revs at 9300 pm and 8600 rpm in sixth gear. (Make sure you test this when buying a used model!)

Like the second gen Hayabusa, the B-king also lets you select a lower power mode, taking something like 1/3 of peak power and torque off the top. Most owners rarely use this, though they sometimes do if riding in the rain and not being in the mood to take any significant chances.

The suspension is also very high-quality on the B-King. There’s a KYB fork and shock at the back that each give fully adjustable preload, compression, and rebound damping adjustability. Brakes are also good spec, with Nissin four-piston calipers on 310mm rotors. The B-King also has an ABS option.

Suzuki B-King Tyre Pressures / Sizes.

The Suzuki B-King comes shod with Dunlop Sportmax Qualifiers as standard, but people often fit fairly aggressive sport tyres to them. The rear tyre is a hefty 200-wide tyre, ready for burnouts.

WheelTyre (Tire) sizeTyre (Tire) pressure (cold)
Front120/70-17250 kPa / 2.5 bar / 36 psi
Rear200/50-17290 kPa / 2.9 bar / 42 psi
Tyre sizes and pressures for the Suzuki B-King

In reality, people often opt for balanced front and rear pressures of between 32-34 psi of optimising for grip (based on people’s recommendations on forums) on the B-King. However you will get a lot less life out of the rear tyre this way.
