Model-Year & Chassis Generation Notes
Beloved global entry-level air-cooled twin using internal cartridge element HF133 (2.9 L); 2004+ faired GS500F models added an oil cooler.
Oil & Clutch Mechanical Engineering Note
Suzuki multi-cylinder family exclusively uses a proprietary M20×1.0 fine-thread spin-on filter (16510-07J00 / HF138)—never force an M20×1.5 filter onto the boss.
