Husqvarna FC450 (fc-450)	AER: 10.9 bar, comp 12, reb 13	45 N/mm, LS 8, HS 1.25, reb 9	102 mm
GasGas MC450 (gasgas-mc-450f)	AER: 10.9 bar, comp 13, reb 12	45 N/mm, LS 10, HS 1.25, reb 8-9	103 mm
Yamaha YZ450F (yamaha-yz450f)	KYB SSS: 5.0 N/mm, comp 12, reb 9	56 N/mm, LS 11, HS 1.25-1.5, reb 10	105 mm

Findings: (1) OEM spring steps confirm the weight coefficient 0.4-0.7% per kg. (2) Rear HS adjusters are almost universally in TURNS (1.25-1.5 standard) - engine deltas must be unit-aware (hence +/-0.25 instead of +/-1). (3) Sag targets are bike-specific, 102-106 mm. (4) Husqvarna/GasGas AER pressure 10.9, KTM 10.5 - never copy across siblings.

Further OEM sources: KTM owner's manuals carry AER pressure tables by rider weight in 0.2 bar steps (ManualsLib). Beta USA publishes a Sachs ZF setup PDF for the RR series (fork 0.42 kg/mm, shock 5.2 kg/mm, all clicks, rider sag 100-115 mm) - applied to beta-rr-300-2024.
