Not sure about the default setting and I think there is no such setting. May be SVC people adjust it during the PDI to match the road conditions of the city or other way. Mine came with the setting at No.5, that means at the exact medium level. The user manual says No.3 is standard and No.10 at full payload. If you have a sensitive back, then go with lower numbers but should compromise on handling and dynamics. If you have a strong back, then a higher setup may suffice but you have to compromise with ride quality. Its a universal fact. If you want exceptional handling, you have to give up ride quality.
