I'm a new rider. I can ride fine in terms of shifting gears and stopping etc. However, I have a problem. At slow speed, I'm stuck in the habit of using the throttle instead of the friction zone. This does not work trying to make a sharp u-turn. So, what is the best drill to go practice using the friction zone to modulate power? I suck at it.

My bike is a lower torque cb500x, fyi.
