Or is it recommended to lower the pressure?
Might sound stupid, but on a race track you obviously put a lower amount of pressure in that automaticly build up when tyre heats up and gets stickier.
I used to take my 910R to a subdivision in construction to "practice". Lots had been laid out, infrastructure done and roads paved, but no houses in construction. It sat basically abandoned for a year or longer while the builder found financing. (mortgage/housing crisis years)
2 large roundabouts and a several bending/straight roads off the main highway. I would ride past the barricade and play......
Toes scraping the pavement and tires to the edge (I only ever get my knee down on a track...old school body position on the street...no hanging off).....OEM Diablo Corsa tires at spec (33-33)....
I have ridden in the North Georgia mountains at speed and scuffed my tires to the edge, looking just like I had been on a track....at spec pressures (33-33).
The key is, on the track you maintain higher temps longer than possible on the street. Hence increased pressure build up and need to lower cold pressure.
When I ride on the street I run what the book says. Bike handles well and tires last as long as can be expected.
Run what the book says.
I used to be fast....now I just dream about it.
