2025 vs 2027

2 model-year records side by side. A row is compared only where manual pages print the value; spec-sheet figures are shown but not judged.

Different on the manual pages

"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.
