Had an hour hour out tonight just before dark and it was getting chilly.
I tried (and failed) to find the limits again.
Now usually its just a case of pushing until the rear starts to let you know its not happy. This has been the case for the the last sets of tyres I've used (ME4's, Conti attacks, Supercorsa pros, Michelin Pilot Sports and Hi Sports) Push until the rear (or front) starts to go.
But the Vipers haven't so far. Now this may be a good or bad thing. Maybe the Vipers aren't going to give the same kind of feedback before they let go. Maybe they'll just let go
More testing this weekend.
