I worked with a chap 1969-71 who was a member of the DZ club He rode a BSA 250 Goldstar we used to go to Kings Heath park during the dinner hour there and back and a quick point in The Gough Arms Upper Gough St , his name Keith Brown . Great bloke , I remember at the lights by the Albany hotel , there was a bloke on a Honda 175 twin cylinder , Keith said to me lets see how good this bloke is ? He should leave me standing if he's good , lights went green I think the Honda is still at the lights ha ha
