My previous tyre was a TKC 80 and I was off the egde (no chicky strips left at all) on pretty much the first few corners, but it had a pretty flat profile so I kind of expected it. My current tyre the Shinko E700 has a very round profile and I'm off the edges of this as well, so while it was off, I thought I would see what sort of lean angle this is and to my surprise it is just under 50 odd degrees....past half 45 and not what I expected and looking at it, its well over alright. I used a phone level app called "Moto Lean" and laid it on the disk, the ground is level and the mitre square confirms its past 45.....all a bit sobering when you think about it, I think I'll take it a bit easier from now on.
Angle is probably less than that as you not taking the bike weight and cornering weight into consideration.
just an observation and seems its not to far from the marquez........I doubt I'm in the "scooter zone".....lol Cant see dynamic load changing things buy that much unless the tyre is really flat.....but as you lean more, the lateral load distorts the tyre and rolls the chicky strip away from the road, not closer.... https://www.facebook.com/RacerZone/photos/pcb.10152931117381150/10152931114301150/?type=1&theater
BTW there are apps for that... https://play.google.com/store/apps/details?id=it.pirelli.diablosuperbiker&hl=en https://play.google.com/store/apps/details?id=com.RidingAngle.RidingAngle
The Terra weighs 183kg at the kerb, say 13kg of that is the wheel and tyre, the rest is evenly spread front and rear, the rear wheel is bearing 85kg of weight. Add the rider, say 80kg, again divided evenly adds 40kg. That's 125kg (277lbs). Think the tyre is not going to create a larger contact patch with 125kg pushing it into the ground?. YOu can always wet a patch of ground and stand the wheel in it and then measure the contact patch, and then sit on the bike with the rear tyre on the wet ground and compare the difference. There is one sure way to check your lean angle... Just download an app onto your phone which measures lean angle via the gyroscope, secure your phone to the bike and go for a ride. I would be surprised if you were getting even 45 degrees lean on those tyres. Remember, the contact patch of your tyre is probably going to be about 1/3 of the tyre width. When you're getting the edge of your tyre on the road, you're probably using the 1/3 of your tyre closest to the edge and the edge of the tyre is the edge of the contact patch. When Marc Marquez is leaning his bike at 64degrees, the edge of the tyre is probably the centre of his contact patch, ie 1/6th of the tyre is in contact with the road, only half the contact patch that you have, which is why he's millimetres from crashing whereas you're well within your comfort zone. (All of the numbers I've thrown around here are mostly made up)
