Model-Year & Chassis Generation Notes
Succeeding the GSX-S1000F in 2022, the WEK0 GSX-S1000GT pairs the legendary long-stroke K5 GSX-R1000-derived 999cc four with ride-by-wire, cruise control, bi-directional quickshifter, and a 6.5-inch TFT (sharing identical engine and fluid specs with the GSX-S1000GX).
Oil & Clutch Mechanical Engineering Note
Built on Suzuki’s bulletproof 73.4 × 59.0 mm K5 inline-four architecture with SCAS slipper clutch, service refill with an M20×1.0 16510-07J00 / HF138 filter is 3.4 L (3.6 US qt) of full-synthetic SAE 10W-40 JASO MA2.
Garage Wrenching Gotchas
- Factory-fitted OEM Dunlop Roadsport 2 tires (190/50ZR17 rear) wear relatively quickly under highway touring loads—switching to dedicated sport-touring rubber like Road 6 GT or Angel GT II doubles tread life.
- Equipped with Brembo radial monoblocks but no factory centerstand, fit M8 swingarm spools for paddock-stand maintenance and carry a compact lift stick on multi-day tours.
5. Frequently Asked Questions (FAQ)
How much engine oil does the Suzuki GSX-S1000GT take with filter?
Refill with a new 16510-07J00 / HF138 spin-on filter is 3.4 L (3.6 US qt), or ~2.8–3.1 L without filter replacement.
How does the GSX-S1000GT compare to the Kawasaki Ninja 1000SX?
At 226 kg wet (~9 kg lighter than a Ninja 1000SX) with a lower 810 mm seat and 152 hp top-end rush, the GSX-S1000GT leans slightly sharper toward superbike-bred excitement.
What cold tire pressures are specified for the Suzuki GSX-S1000GT?
Suzuki specifies 250 kPa (36 PSI) front and 290 kPa (42 PSI) rear cold for both solo and fully loaded touring.
