Hugger from DP not yet available , Georgina keeps saying they are coming but nothing happens
Exhaust , full system 57mm with Titanium silencer is available now , approx £2500 plus VAT
Or you can buy a silencer for an assymetric system for a 749S , the carbon cover and a bolt kit (standard silencer attachments are studs with nuts , race silencer has threaded inserts and bolts) and fit using the standard pipes , for best results get the cat cut out of the front pipe.
The slipper clutch only does the "spooky silence" thing when your are riding slowly , when it happens just blip the throttle with the clutch out and it sorts itself out..............or buy a DP or STM clutch , approx £600
I'm sure you will enjoy the bike , they are very special
