understanding KTM shock spring numbers? PDS4?
I just picked up an 02 KTM 400exc that is plated and the suspension seems very stiff.  The number on the back spring is a pds4.  I have searched, but I havent found anything that explains the pds numbers in regards to rider weight.  I understand that its a progressive spring.  Can any one shed some light on this?
