Full Lock? Do You Have Complete Control of Your Motorcycle?

Can anyone out there ride full lock? I can’t! I hate that I can’t! If you can, do you think it has to do with the model of motorcycle you ride? Is it all mental? Does it just take practice? 

Diana and I will be taking the Ride Like A Pro course offered in Mechanicsville, MD soon. There is also a class available in Mountainside, NJ. I saw this on the FAQ page of the Ride Like A Pro New Jersey website:

If you can take your motorcycle, turn the handlebars full-lock and scrape a perfect circle in the ground with your pegs or floorboards without dropping your bike or putting a foot down, you’re in complete control of your motorcycle.
