Well said ceo.
The only reliable way to measure a person's riding ability is to take a look at their 12 o'clock bar.
Let's take a look;

The above bike is obviously not seriously ridden. The 12 o'clock bar is almost untouched, the can has not been chopped, the tire still has tread...pitiful.
Whoever rides this bike is obviously a huge squid. You're average segway rider could destroy him in the twisties. They probably also love the cock.
Now compare that to this;

This bike is obviously ridden by a pro, probably WSBK/MotoGP caliber rider. Notice the destruction of the rear tire, the abuse put to the 12 bar and just look at the size of that sprocket, almost as big as the rear wheel. It's a safe bet that the rider of this bike has several lap records at multiple GP circuits to his name.
