Nothing causes as much confusion or trepidation in riders as emergency braking. How hard can I brake? Will the front wheel lock? Will I go over the handlebars? How far can I lean over on the brakes?
As a Motorcycle Instructor I am continually amazed at how many of our students, who have generally had some training and are licensed, come to us with inadequate braking skills. It’s super important to understand and regularly practice emergency braking on your bike. Normally I recommend a quiet car park with a slight up-hill.
To understand braking we must first understand grip. The main contributor to grip is the weight or load on each tire. The ratio between the maximum possible grip and the vertical load is called the coefficient of friction (μ). To understand this, slide an eraser across your kitchen table. Now try the same thing pushing down hard on the eraser.
This same thing happens when you brake on a motorcycle. The bike pitches forward transferring weight onto the front wheel, increasing front tire grip. More so with sports bikes, tall with short wheelbase compared to cruisers, which are long and low.
