Not a flat-out burn - too narrow and too many iffy bits of surface - but some great slow-speed corners down here in the vale of the white horse, particularly the little complex of esses below the Dragon Hill! And you can see the white horse itself etched in the hill on the right on the way back :-)
Perfect Africa Twin territory. Narrow, sketchy surface and huge fun
Perfect for my Africa Twin, some sections too broken and bumpy for a sports bike. I did it on a Monday evening in May and it was deserted, suspect it gets busier at weekends.
