The old adage of not only knowing your own personal abilities and limitations but those of your bike and roads....Honestly, there is no point in comparing to anyone else. We are all at different levels at basically everything we do. The whole point is to keep learning and improving. In my opinion, Anyone riding a motorcycle that is not capable of using all of the tire, lean angle, and turning ability is putting themselves in danger to some degree. Even if you don’t want to ride like that all the time, knowing how to should be a skill you are working towards.
You would not drive a car, plane, boat, ect. And only be able to use half of its turning ability. It wouldn’t be safe. Why do it on a bike?
Some roads just aren't suitable for hard riding.
