Suzuki Katana 1000 Maintenance Schedule and Service Intervals

Suzuki Katana Glass Sparkle Black press photo

This is the maintenance schedule and associated service intervals for the Suzuki Katana 1000 made since 2019 for a 2020 model. It’s also known as the Suzuki GSX-S1000S Katana, but everyone just calls it the Suzuki Katana.

This maintenance schedule is very similar to that for the GSX-S1000, as it’s based on the same underlying platform.

The Suzuki Katana is a naked bike with an edgy retro design. As with its GSX-S1000 stablemate, its engine is a technologically updated block from the highly acclaimed longer-stroke 2005-2006 K5 GSX-R1000. This is a retro bike for Katana but it’s also a throwback to a very futuristically designed model which wasn’t terribly well-received at the time (but which is now a classic).

What you need to service your Suzuki Katana

Below is a list of the things you’ll need to do a service on your Suzuki Katana, aside from general standard motorcycle maintenance tools.

PartSuzuki Katana
OilSuzuki (like most motorcycle brands) requires engine oil with JASO MA spec, or at least API SF/SG or SH/SJ spec. Many oils fit this. Suzuki recommends SAE 10W-40 weight Suzuki motor oil, but I wouldn’t over-think this and use another popular high-grade oil like Motul 7100.
Oil filterUse a Hiflofiltro HF138RC, which is a drop-in high-quality replacement.
Air filterUse a K&N air filter as a drop-in replacement, part number SU-9915.
Spark plugsThe standard spark plug is NGK CR9EIA9, an iridium plug. You need four.
Brake fluid/Clutch fluidSuzuki (like most motorcycles) requires DOT 4 brake and clutch fluid.
Brake padsMost people upgrade their brake pads to EBC ones for better performance (and they’re very affordable). Use EBC part codes FA447HH for the front (two pairs) and FA174HH for the rear (one pair).
CoolantSuzuki only requires a coolant that’s “compatible with an aluminium radiator”. Most motorcycle coolants are, and so Valvoline Zerex G05 is a fine option. Honda coolant is excellent value for money.
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 Katana Maintenance Schedule

Below is the maintenance schedule for the 2020+ Suzuki Katana.

Maintaining your Suzuki Katana is much like maintaining any other big naked bike. You have a chain drive so you have to lubricate the chain, you have to change the oil and filter, and replace the fluids every 2-4 years.

Interval: This interval should be judged by number of months or odometer
reading, whichever comes first

NOTE:

  • I= Inspect and clean, adjust, replace or lubricate as necessary.
  • R= Replace
  • T= Tighten
  • * Coolant — If using super long-life kind (e.g. Honda Coolant), replace every four years or 48,000 km; otherwise, replace every two years or 24,000 km.
  • (California model only) and (CA only) means that the items or the maintenance interval are to be applied only for the California model.

About the Suzuki Katana

Like the Suzuki GSX-S1000F on which it’s based, the Suzuki Katana is powerful sport standard bike.

The Suzuki Katana takes the raw energy of the K5-8 GSX-R1000 and makes it more comfortable, adds some safety features, puts more oomph in the mid-range rather than at the top end, and gives it a lot more retro style.

The Gixxer-based engine is a long-stroke (73.4 x 59.0mm) inline four-cylinder engine. It doesn’t rev quite as high as the old GSX-R’s motor — it has stainless steel valves rather than the K5’s titanium ones, and it has revised cam timing. Combined with lower gearing (two additional teeth on the rear socket), there’s no question that the Katana’s engine is tuned for torque. It buzzes a bit when running at speed — at 90mph (145 km/h) in top gear, you’re doing 6,000 rpm… so uh, maybe slow down a little.

The Katana is no slouch in power figures, either. It shares the same updated engine in 2018 as its GSX-S1000F cousin, and makes 108 Nm (80 lb-ft) @ 9,500 rpm, and 113 kW (150 hp) @ 11,300 rpm.

Even though it looks a bit like a naked bike, don’t mistake the Suzuki Katana for something like a Triumph Bonneville. The seat is somewhat minimal and the bars are a little lower than what you’d get on a naked bike. The position is definitely “sporty”, more like what you’d expect of a streetfighter-style bike. There’s another cue to slow down and enjoy the torque down low — there’s no wind protection.

The suspension isn’t sportbike firm, but it’s good. The Suzuki Katana has fully adjustable inverted 43mm KYB front and rear shocks, adjustable for pre-load, rebound, and damping. You can find the limits of the suspension on the track or in very aggressive street riding, but when you’re on rough surfaces, you’ll remember that this is a street bike.

Braking is also impressive for the Katana, with dual 310mm discs and Brembo monoblock 4-piston calipers.
