As for those doing a 06/08 R6 conversion the spring rate is 8.4kg/mm but the dry weight for this motorcycle comes in at 417lb and the same scale ...73kg rider naked.
Not that you would see me riding naked
Anyhows i figured those who ditch the std pipes it would come in pretty close to the same weight anyhows if changing to an R6 rear shock so all you need to do is come in at the correct weight and ride naked and you will have the perfect suspension.
Try telling that to the JUDGE
