Croz's bio didn't give up too many cornering / sliding secrets but I have an excellent list of pubs near english race tracks, priorities!
Just for the sliding / cornering discussion, from Peter Cliffords 1982 book "The art & science of motorcycle racing" (Clifford was a technical journalist and road racer, engineer and editor of Motorcourse in the eighties).
A quote about the difficulties of describing handling techniqiues...
"There is no established language to convey the exact feeling that the handlebars give as the front wheel begins to slide and turn in, the timing required to gently ease on the throttle so that the rear wheel begins to slide in harmony and the weight is transferred from the front to back wheel, the front wheel being hauled into the inside of the corner by the pull of the chain."
Essentially this style has been around from the 1980's and is a well established method of aligning the bike in the direction you want it to go, Mamola was good at it.
Just another quote to set the cat amongst the pigeons regarding learning on the dirt...
"It has often been suggested that American riders are able to control a sliding motorcycle because of their dirt track racing experience. Roberts (KR senior) disagrees: "I don't think that riding a dirt tracker teaches you anything very much that you can't learn on a road racer, but I think I learnt to be more agressive and determined because of dirt track racing in the States. When you are on the start line on your Yamaha among eighteen other guys on Harleys, and all the Harley fans in the crowd are throwing their beer cans at you, then that teaches you to go fast.""
Amazing what you can learn from the past,what's that saying? Standing on your grandfathers shoulders?
I should take this shit to The Perfect line, I could have a feeding frenzy
