It takes a bike swap...

I was thinking on the min speed before opening up and accelerationg out
of the curve (but not well formulated . . ). I obviously seem to ride
like a nun since I have ended up at slightly below 50[1] before starting
to accelerate out of the M25->A21 sweeper. To me, it looks like it has
a decreasing radius, which always sounds the alarm bells for me.

The SS tyres allows much better grip, but I tend to look ahead rather on
the speedo when on it )

[1] on the K; and calibrated speed on the Sigma computer,n not the BM
speedo.

 

That was what I quoted, although obviously I'm going by my speedo
readings which are probably optimistic.

On the A21->M25 left-hander, I can just chuck the bikes in at 90 and let
them do the rest.

On the M25->A21 tighter bend, I chuck them in at 65+. Exit speed depends
on when I open them out.
