The records are for different markets (2024: US version; 2027: Australia version). 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.
