Ive got that motorcycle chock, and it sits in the back of my truck year round.

It has been used and abused, more times that most people here would use it.
Holds up any bike without someone holding onto it, and secures the front wheel.

The downside to it, is it doesnt fit the Honda 125 or Ninja 250 front wheels all that well.

Other than a shot of spray paint, mine works great.
