Threshold Braking: Why is it "free" at higher speeds?

You already reached a deceleration rate of 0.8g's at lower speed
If you can average 0.8g stops at lower speeds, it's easier to do it at higher speeds
Rolling coefficient of friction is lower at higher speeds

Dragging a Peg: Why should you lean your body into a turn if you drag a peg?

A peg can handle being dragged easier than your body can
If you lean away, you drag the peg harder
This raises the side of the motorcycle you're leaning toward

Lean Angles: Why is a lean angle of 30 degrees half of a lean angle of 45 degrees?

Lateral acceleration (g force) is double at a 45-degree angle compared to a 30-degree angle
Engine guards are twice as far from the ground
It's harder and harder to increase the lean angle, the higher it is

Gravity Surprise: Why does a motorcycle "fall" up instead of down when braking in a curve?

Camber thrust decreases and causes slip angle to do the same
Weight transfer lengthens the wheel base, making the lean angle greater
Contact patch loses traction, causing slide angle rather than slip angle

Quick Stops: Why is it harder to practice quick stops at 30mph than at 60mph?

Skid risk is higher because weight transfer takes time
Less time is available to reach a high average squeeze pressure
Rear brake takes more time to apply than is available at a lower speed
