You also need to get over your body telling you that what you know you ought to do is a VERY BAD IDEA. Our brains are wired to think we are falling after we lean about 15 degrees from vertical.
Only the visual and vestibular systems. Proprioceptive systems are faster, more sensitive and less concerned with positional deviation. Training is necessary to force the body to rely on the most reliable perceptive system in the physical circumstance, and disregard those that are dissonant. In flight, that means disregarding your "seat of the pants" and trusting visual inputs, initially, and then you learn to re configure the dissonant inputs in a special setting.

My streetbike tires are good for about 50 degrees of lean once warm and that's not even including the additional center of mass effective lean angle from getting off the bike. That's a long way from where your brain is telling you you're over too far and where you've even gotten near the limit of what you're capable of. You can KNOW this fact, know that you are well within your lean angle limits, you can do the math, trust the calculations, you can even get passed by guys leaned over further, going faster than you are and STILL not be able to get your brain and body to push any more. Theory is great, but it's not a ticket to accomplishment.
But only objective theory will tell you how to ultimately resolve dissonant inputs into the objective framework for action. And you have to depart those limits over and over again to learn how close you can come before corrective is impossible. Until you lay the bike over a few times you will never truly know how far you can trust your perception to take it. For obvious reasons you shouldn't do that at full-speed -- but by all means you MUST take it at low speeds to where the back end starts to go and then correct-- and keep working that that dynamic upward in speed as your perception scales itself to the boundary conditions of the objective performance of the machine. What theory -- and ONLY theory can tell you is how tight a turn and line of entry at a relatively LOW speed you must take to enter the stability boundary you are trying to (safely) explore. Once you begin to learn that departure pattern at various speeds the structural intuition comes into play and predicts a pattern for a speed or entry line you have not yet attempted.

The body is no different. When nikkyo is applied, the body is dropping looking for a stability it has not lost before the mind knows it has happened. When sankyo is applied his body is rising in search of a stability it has not lost-- the minid is a late player in this game. Uke learns oodles from this -- if he is paying attention and has been given the categorical tools to tell him what to note as it occurs. Aikido is both using the proprioceptive mechanisms to sense the opponent's structural state (kokyu tanden ho) and triggering the operative elements of that same system to create destablizing access to enter and then accelerate departure from stability. In action, it is using those same structural systems to move more effectively itself.
