Hello Tim, I will give my humble opinion.
I do the Italian Endurance Championship with Ducati TT1, I use a steel bar mounted on two bearings, I hung a piece of metal with a wire and screwed with your wrists back and forth, until your arms will fall on the ground!
Train yourself just a little 'and everything will go fine.
I had the honor to race with endurance Laverda SFC Augustus Britons, and I can assure you that the Laverda SFC has a clutch very very very very HARD!
Experience beautiful, but cramps in my arms!
I forgot, we won the race!
Ciao Carlo Leoncini.
