I've done over 40,000 miles on 5 Ducati's, ST4, ST4S, 996SPS,
996R, and a Multistrada and have had very few problems, although they definatrely need more attention than say a VFR.
The sum total of my probs/warranty claims have been, warped discs & leaking shock on the ST4S.
Warped discs on the Multi.
2 rockers on the SPS (not warranty)
the SPS and the 996R were bought secondhand.
I had enough faith in the Multistrada to take it to Morocco and the Sahara desert and there isn't a Ducati importer or dealer in Morocco.
The dry clutches don't last that long though, character
