BSA A65L, 1970
Thanks to Mark of Australia for this picture of his bike.
Mark has had A65s since 1972, before that a 1950 A10.
This particular bike is his main transport used every day. The motor is a 1970 A65L, its now 883cc with a 90degrees Norton crank and alloy cylinder that he made himself.
It's pretty tall geared with C/ratio 1st and 2nd giving about 78mph and 105mph at around 7,000. The motor is rubber mounted so it's quite smooth.
