At last someone who knows what they are talking about, well done David G. Our old Morgans used to go for many thousands of miles with good old chains and sprockets, talk to the bikers who have a lifetime of experience of chains and sprockets. You don't see that many proper race bikes with belt drive, I wonder why.
still I am only an old prat who makes his own pulleys and sprockets for high end drag bikes. Good luck to the maker who comes up with an ultra high price bolt on goodie for what is basically still a 1930s trike.
