Neal Saiki left NASA to use his engineering talents elsewhere, which led him to the Zero MX motorcycle. The Zero MX is an enhanced version of the Zero X. It includes better forks, shocks, wheels, and tires in comparison to its predecessor.
A customizable shock that can be specially fine-tuned pretty much completes the bike. The Zero MX is not the biggest, heaviest, strongest, or fastest motorcycle ever, but it was designed by a former NASA engineer, so I have to give a little credit where credit is due.
