Lean angle, chicken strips and tire pressure
My brand new 2020 RR is the first bike Iíve had with a lean angle sensor/display. Iím wondering about the relationship between the displayed (actual) max lean angle, rear chicken strips, and tire pressure. Iíve only had my bike just over a week and 400 miles, all on the street. I donít even have my first service and rev unlock yet. But with everything new, I see about a half-inch rear chicken strip (I donít take it near the limit on the street) and have a fairly symmetrical max lean angle of about 43-51 degrees most rides where I hit some good curves. Leans over 40 degrees also constitute a minuscule amount of my street riding time.
Iím running stock tire pressures (near 36/42 psi) on the street, though am tempted to lower them (especially the rear) fairly substantially so they are closer to what I would run on the track. Reducing tire pressure would expand the contact patch and help absorb bumps when leaned. I would think that at a given lean angle, a lower pressure would also eat into the chicken strip. I donít care about chicken strips except as a metric to better understand tire dynamics. I also understand there are many other variables such as tire type and body size and position (good hang off reduces lean at a given lateral acceleration).
Iím hoping to get some knowledge from those far more experienced. What can you tell me about the dynamics, tradeoffs, and anything else important here? What pressures would you recommend for fairly typical sport street riding with the stock tires?
