         660R fork help needed...seriously confused 
 
         Hi Guys
        
 So I just opened up my forks for the first time and big surprise!
 
 I found a 30mm spacer and a progressive spring!
 
 Now for the confusion part.
 
 The factory springs arent progressive are they?
 
 If it is a after market progressive spring it shouldn't need a spacer right??? Spring is 630mm long and 5mm diameter.
 
 Air gap is 425mm
 
 Thanks for any input
