about the only advantage an open primary has is being able to swap out the primary belt in a short amount of time,
a big washer to hold the clutch spring assembly together and you can have the clutch hub of and back on in ten to fifteen minutes.
if they were running an open belt in gravel, my bet is they would have replaced several belts,
now if they were running a primary chain they would have used "a bit" of oil,
assuming they actually "oiled" the chain occasionally.
and required a several "adjustments" daily!
Regardless of "either option" by the time that bike got home (assuming it did)
all of the clutch plates, bearings, the clutch hub and possibly even some of the transmission main shaft would have been junk.
I do like the concept of the Thriumph/HD bike, for someone that wants an HD that stands apart
but the truth is all that bike would ever see is the tail light of a Bonneville.
