Would agree with Captain that it is the end of Cronk y Voddy. I have watched from the apex of that corner a few times. I can't comprehend how the top riders can take that corner at the speeds they do. Absolutely terrifying corner. Top riders only seem to lift off the throttle slightly then tip in, crossing a big bump caused by the road camber. My heart was in my mouth the whole time I stood there.
Also agree with Sam that it could be Sam West.
I done some sleuthing in regards to the last pic, and thought I had the rider. I trawled through old programmes and thought it had to be Mark Parrett on a stock BMW. So glad I got the rider as wrong as the corner. I gave up thinking it could be at Greeba as something didn't fit right, caravan up in the hill and the fact I thought the shot would have had to have been taken from far back with a zoom lens to get the sign in. Got the old grey matter working though. So thanks again to all who keep these teasers coming.
