Great engine stand to have when rebuilding the engine in the Honda NSF250R or RS125. Allows for stability and frees up a spare hand when trying to work on the motor. Also has a cool feature that holds the engine flat when you are installing the transmission.  These are in very limited supply and we only get a couple in per year.
