The second pix is just killer. My bike will wheelie, but I never do it, don't feel like blowing fork seals. When I had my dirt and sport bikes I was always riding wheelies.

 

ive gotten my front end up a little coming out of a turn. Down shifted into first going it and hit it on the way out. 1st gear is like a rocket on my bike. i wouldnt really call what i did a wheelie but i can see how it could be done
