By model year

Kawasaki KX250
2003–2004 vs 2026

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.

On the manual pages

0 different0 the same0 printed differently21 not compared

No row has manual-page values that differ.

The records are for different markets (2003–2004: not stated; 2026: US 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.
