As an interesting note, and I hope I am not getting too far off track, When I ordered my Dave Hills center stand, I measured the rear pivot bolt distance as he specified, and got 12-3/4 inches. Dave commented that this was about an inch taller than typical, and was the second longest stand he had made, let alone for a B. I think my stand is a bit long now that things have settled in a bit, but the combination of the front and rear Thornton's and the Justin Mackay-Smith rear springs and spring boxes put the thing up in the air a bit. That is probably why my front stands are vestigial appendages now. B's should be lower than C's and a comfort to shorter inseams. Anyway, that is something to consider if you want to change to a Brampton coil over.
