I think, they are - or were in their days.
I proved it with my 1981 Triumph Tiger Trail, even today they do it, for example, with the Triumph Scrambler (take a look at that thread). I even did it with a Suzuki GN 400 TD, a road-version of the old Suzuki DR/SP 400. But I won't show this bike here, that doesn't fit to the theme.
But I'll try my Trail, hope it works!
Kind regards, Bambi
PS: Steve, could it be possible, that you saw my mis-use of the term 'sucks' in the Africa Twin-thread? I'm so sorry about that! And remembering this thread, I think, that Stormforce´s A-Twins should be shown here, too ...
