4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Badged 900 while displacing 865cc; 2004–2007 carbureted bikes wore true clip-ons, whereas 2008–2015 EFI models switched to slightly raised low-rise bars.
Oil & Clutch Mechanical Engineering Note
Sportier cam profiles and higher compression in the air/oil-cooled 865 twin favor full-synthetic SAE 10W-50 or 15W-50 JASO MA2 (3.8 L w/ HF204).
