I don't buy the Harley angle at all - Harleys are big, heavy, bloated machines, whereas Rics are lean and mean.
I think a more appropriate simile for Rics is a Lotus: a bit of a bumpy ride, the odd squeak and rattle, a bit of a reputation for having issues which need fixing, but a great piece of kit and by crikey they are fun!
(I am a Ric and Lotus owner...)
