Thanks all, I'm a fit, 6'4" 59yr old so the manhandling bit isn't an issue.
Thanks for all your replies - I might have a ride on one but, having read the Stormtrooper notes, I'm more than ever inclined to say the Gen 3 650 is possibly my perfect motorcycle. I almost always ride solo, without much kit, an overnight bag maybe - I never seem to need the hard panniers I have, just the topbox. I'd love a bit more go but the relaxed ride, astonishing mpg and the fact that it is a known quantity, already paid for and living in the garage is a strong argument in its favour. I probably need to ride it more to appreciate its qualities! I recall I sold my Stelvio, a scorching road burner of a bike in the same style, because it was too big and too heavy for B roads and general fun. Excellent if you are a "committed personal best time from A to B" type rider but I'm not that anymore - just a trundler with occasional A road "get to the destination a bit quicker" type moments
