the old w800 always looked too small to me. more tr5 than bonny. i love the ducati bevel pushrod tube copy but i dont think hinkley and their bonny range has much to worry about.
I rode beside one on a BSA camp ride-out. It seemed large compared to my GF. Mind you, the plunger is a low machine.
I was impressed with the Kwaka, so much so that I seriously considered flogging my BSA to go towards buying a new W800. In the end, sanity prevailed.
If I had the money and the room to house two bikes I'd like one of the new version's
