Took the 75, freshly shod with some quite funky Marangoni tyres up to the MOD training ground in the Epynt mountain.
Surprisingly traffic-free run and I can report that, although the Marangonis aren't as grippy as P6000s, they're very forgiving, meaning I was a lot more confident in getting a boot full of power down coming out of the bends.
Did around 120 miles all-in but came back with a blowing exhaust.
Getting a pair of ramps tomorrow to investigate.
A couple of pics:
