After exhaustively researching limited resources (Project 1201 etc.) for SL target rider weight design specifications, suspension engineering data (titanium rear shock spring and fork springs) escapes revelation. Granted, engineer(s) factored in consumer weight variations within a doubtless tight range relative to the Ti medium limitations. Perhaps consensus is that assembly adjustment should account for the lading range. Is the applied engineering target rider weight spec available to anyone here (or nonexistent)? Devoid of roadrace team exposure, I'm admittedly blind.
