Today I dusted off my trusty kushitani one-piece suit, which hasnt been worn for maybe two years or so, and (after happily finding that I can still fit in it) I took the 12 out for a play purely in the interests of research.
Anyway, on D607s I found I could get me knee down on an old favourite 4th-gear roundabout without too much trouble, though I think I was still some distance from touching any of the bike down. It seems too that the tyres on the 12 are quite tall and thin, so it's very difficult to actually get to the edges of them (a good thing I guess). ...
