'Involving' is pretty straight forward...you have to learn and understand stuff about the bike and work with it to get the best out of it.
Sometimes that's fun, sometimes it's nice not to have to be involved or to have to think much about what's happening with the bike...just relegate the bike operating related activities to a corner of the brain. eg lots of things happening around you/risk/danger or long journeys with nice views n' stuff.
'Involving' seems a useable attribute when describing a bike.
'Inspired' should be kept for brilliant and novel designs that move the whole 'bike thing' forward. It's better suited to marketing spiel like - 'adding a 2006 road version of their iconic 1950s TT winning 500cc 'Thunderguts' was an inspired move. Despite scepticism it sold well and elevated the brand profile for very little outlay'.
Something similar to that.
although I think modern Ducatis are becoming less involving as they try to reach the same levels of day-to-day usability/reliability/ease of use that the modern motorcyclist seems to want.
Go back to my old Pantah (for example) and the thing was genuinely involving to ride - you needed to concentrate hard to get the bike to do what you wanted, which is NOT to say it didn't handle - it just required positive input, rather than passive acceptance (which is more the norm these days I feel). It took experience to get the best of it, the rider was far more a part of the ride.
Inspiration and Passion can also come from the process of being involved with riding a bike - the more involved you are, the more a part of the ride you are, rather than being a passenger: then the more satisfaction and sense of achievement you can draw from the whole experience - the more satisfaction you can draw from something, the more passionate you will feel about it, and the more inspired you will be to do it again.
'Tis one of the reasons I don't like riding most modern bikes (on the road), they're far too "good", and to be truly involved with riding them, to truly make your rider inputs more a dominant part of the ride you need to be doing some truly silly speeds; speeds that belong on a track. There's far more satisfaction, involvment, passion and commitment in riding a bike that isn't a piece of white goods.
