Another very good photo.

Looks like the right arm of the rider had some excessive wear.

I saw a young man take a curve (300 degree turn on an uphill slope) too fast at Lake Okutama in Japan. The left foot peg ate the asphalt and he and the bike went in different directions. Fortunately he was well padded in a new set of leathers. The only thing damaged on the rider was his pride and some road rash marks on those new leathers.
