I've seen just over 110 on the clocks by the nasty hairpin before looking up, so 100-105 at the apex seems about right.
I'd be stunned if anyone outside of national racing can hold a 120bhp bike through there flat out (except certain "local heroes"). I'm sure that would be pushing 130+ through there. I know it's got a lot of positive camber, but 130mph through coppice is
As we're going to be there in March and October I don't suppose we're likely to see the sort of track temp/conditions that would give us the chance to have another crack at holding it pinned.
