Rodehard Posted February 18, 2018 Report Share Posted February 18, 2018 "Need to", no. Your bike has the rubber damper "cush drive" setup in the rear sprocket carrier, this takes care of the driveline shocks. The rubber covered front sprocket is for NVH purposes - might be a little louder sounding, but no harm will come from using the solid front sprocket.

I replaced my F4I without one and never noticed any difference and doubt you will. 1 Quote Link to comment Share on other sites More sharing options...
