They only made them for about 3 years. My 1st BSA was an A10 when I was about 12. Still got the scars from getting thrown over it when it kicked back when I tried to start it.
It was Mason, he's the one on the back end of the bike. He's 18 in a few days time 22 December. I've got a video of that day Bob, i'll see if I can upload it on to this topic.
