Model-Year & Chassis Generation Notes
Fuel-injected from 2005 onward as the Boulevard C50 (Intruder C800), combining classic valanced fenders, floorboards, and low-maintenance shaft drive.
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.
