Just lowered the seat on my 2019 pikespeak 1260 and there is now a gap between the riders seat and the pillion seat. i looked on one of the ducati parts web sites but i could only see the parts that i removed to lower the riders seat. there is two threaded/fixings for bolts on the underside of the pillion seat that looks like you could fix a spacer to bridge the gap. Is there a part missing on my bike?
