What should the position of a moped be in order to achieve the optimum effectiveness of braking?
Show the correct answer
Correct answer
A. Vertical.
Explanation
In the photo a rider in a helmet is sitting on a white and red scooter held upright, at the entry to a road. You get the best braking effectiveness with the moped in the vertical (upright) position - answer A.
When a two-wheeler is upright, all the grip of the tyres can be used for braking. When it is leaning to the left (answer B) or to the right (answer C), part of the grip is already used to keep the moped in the bend, so less of it is left for braking - pressing the lever too hard easily ends in a skid and a fall. That is why before a bend you brake on the straight section, and when you have to brake in an emergency in a bend, you first bring the moped upright as far as possible, and only then do you brake harder. You use both brakes at the same time.
