Would definitely agree that :
Chain maintenance
Carrying Stuff
Cleaning
Can all be a massive P.I.T.A. on a regular motorcycle, but IMHO a decent chain oiler and topbox can go a fair way towards addressing the first two - I also hate carrying a lid around - and as for the last one - it'll get a proper clean about once a year
(always gets a healthy squirt of cheapo WD40 substitute after a wet ride though)
