The records are for different markets (2023: US version; 2024: US version; 2025: US version; 2026: not stated; 2027: not stated). Figures can differ between markets, not only between years.
"Not compared" means fewer than two records have the value from a manual page; it says nothing about whether the bike changed. "Printed differently" marks descriptions (the fork, the oil, pressures with printed conversions) that the manuals word differently; read both before assuming a change.
5 model years: the table scrolls sideways, and the spec names stay in view.
