About this baseline
For a 75 kg Intermediate rider with a Neutral style, the baseline for the Husqvarna FC 250 2025 at Log Road MX shifts 11 of 13 computed settings away from the OEM standard. The biggest shifts: Fork height in clamps 3 ring (-2 vs OEM), High-speed compression 1.5 turns (-0,25 vs OEM). All values are computed from OEM defaults and your rider and condition factors.
Value provenance: OEM = manufacturer specification · verified = confirmed by an expert · reviewed = editorially reviewed reference · community = confirmed by the community (median of at least three public setups) · computed = automatically derived by the LAISA engine. Automatically extracted and unconfirmed values never appear on public pages.
