Troy Lee Designs (TLD) is an American action sports apparel and custom paint company founded in 1981 and headquartered in Corona, California.

Besides custom paint, his early product offerings were limited to custom-made visors for motocross helmets, which he vacuum-formed in the oven in his mother’s house in Corona, California.

The terms of the airport lease were such that Troy was required to dedicate 40% of his business to aviation related services, so he began painting registration numbers on private aircraft.

In 2001, Troy Lee formed a supermoto race team featuring himself and supercross and motocross racing's Jeremy McGrath and Jeff Ward to contest the newly formed AMA Supermoto national championship series with equipment support from Honda and title sponsors Red Bull.
