Hi John, Rocker is absolutely right! Delivery timescales can be a bit erratic to say the least.
I ordered a whole host of DP stuff at time I ordered MS last March/April. Bike arrived May but first 'stuff' to arrive was Comfort Screen and Panniers at end of August. Therafter it's probably averaged 1 part every six-eight weeks or so. Of parts originally ordered I'm still waiting on Carbon Belly Pan.
I've held off ordering any other carbon goodies to see who of after-market suppliers can beat Ducati to it.
