One for Andy Lorenz, but I believe the serial numbers were sequential across all unit singles.
So b44b 0002
And so on.
Allan my friend.......I do believe you're right. The Roadster was a one year only bike in 67. It was the road model and had a square barrel while the others had a round barrel. That all changed in 68......still the road model but with some different bits.
B44R 101 is what I thought they started numbering them for the Roadster ( Shooting Star in the US)
C25 101 for the 250. My highest numbered 67 is 1775.
I believe Tommy's bike could be one of the last of the 67s........I'd be interested to know for sure.
HAPPY FATHER'S DAY to all the dads out there, Gordon in NC
