Lee — son of an artist and motorcycle racer, grandson of a Bonneville Speed Trials co-founder — gave up racing to focus on custom paint and vacuum-formed helmet visors made in his mother's oven in Corona, California. The burnt-plastic smell forced the business out of the house and into a hangar at Corona Municipal Airport, where he also painted registration numbers on private aircraft. From there TLD grew into a full line of motocross and mountain-bike helmets, jerseys, gloves, pants and protective gear.
Headquartered in Corona and still run by its founder — co-owned with investment partners Fasthouse — Troy Lee Designs fielded a championship-winning supermoto race team in the 2000s and sells worldwide through distributors in 15 countries, with US retailers including REI and Backcountry.
