MSF Cornering and Turning 3

Question 1

What is a 'decreasing-radius curve' and why does it require extra caution?

Accepted Answer

A curve that tightens progressively, demanding more lean or speed reduction

Answer

A decreasing-radius curve gets tighter as you proceed through it, requiring the rider to either reduce speed beforehand or increase lean angle mid-corner.

Question 2

How does a heavily loaded motorcycle (passenger + luggage) behave differently in corners?

Accepted Answer

It has slower steering response and needs earlier entry speed reduction

Answer

Added load raises inertia, making the motorcycle slower to initiate lean and harder to change direction, so speed management before the corner is more critical.

Question 3

What is the purpose of the 'late apex' cornering technique?

Accepted Answer

To delay the closest approach to the inside, allowing a safer exit

Answer

A late apex keeps the bike on the outside of the curve longer, allowing you to see farther and straighten the exit sooner for a safer, more controlled path.

Question 4

When cornering on a slippery surface (wet road, sand), how should you adjust your technique?

Accepted Answer

Reduce lean angle and increase corner radius by entering wider and slower

Answer

On low-traction surfaces, reducing lean angle (which means wider, slower entry) keeps cornering forces within the reduced traction available.

Question 5

Which statement about countersteering is MOST accurate?

Accepted Answer

Pushing the right handlebar initiates a right turn

Answer

At speeds above approximately 12 mph, pushing forward on the right handlebar causes the motorcycle to lean and turn right—the fundamental principle of countersteering.
