Knowing the limits is fine, but approaching them regularly on the street isn't. Attaching a lean angle "number" to the cornering process is somewhat irrelevant. Knowing what touches down first is important. From my experience the only place you can safely reach those limits is on a race track, where you are able to push the bike further than on the street.You need to introduce us to your technique for going around a turn. To me the only way is to lean the bike over. So knowing its limits is rather important.
