Bantam.

Spent the evening at J and T's. His latest acquisition (to assuage the onset of mid-life?) is a 1951 BSA Bantam. O took an instant fancy to it....and the leather jacket and open-faced (obviously) helmet that completes the look. As J says, 'it's a lifestyle thing'. Must be, seeing as bought it having never ridden a bike before and had to take his basic training test before he could ride it. Looks good, though I don't think I'll be following suit.
