Just got back into Ducs with an st3s. People complain about the headlight on the 2's being wimpy. Regulator/wiring issues are pretty common on the older 2's as well. Fuel pumps can be problematic, but there is a generic bosch part. Belts every 24 mths according to Duc, but folks go longer. Not hard to diy. Valve adjustments are a regular thing, and they're a bit of a pain, shims and closers.
Upgrade the stock saddle to the later (o4 and after) as its gel and more comfy.
There's a good faq etc in the ducati.ms sport touring forum.
