You’d be hard pressed to break the average speed limit on the twisty bits in a normal car but its fairly easy on a bike but the consequences of running a bit wide on the blind bends don’t bear thinking about.
A few years ago I was following a guy on a TL1000R who went into a left hand bend a bit quick, braked too hard instead of leaning it further and lost the front. He slid across the opposite lane (luckily there was nothing coming). I stopped to help him collect the wreckage and he told me that was the third time he’d ridden the cat and fiddle that day so he had a circuit set up and was trying just a little bit harder each time.
Funny thing is that I’m Captain Slow over that road and when he came past me i carried on at my normal pace and stayed with him, the corner he binned it on was nothing special, in fact I don’t think I even needed to brake until I saw him slide across the road in front of me!
