Model-Year & Chassis Generation Notes
Bridged the Gen-2 and Gen-3 SV650 from 2009–2015, introducing a steel trellis frame and twin-spark 645cc V-twin taking 2.75 L w/ HF138.
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.
