Mark Cowan

Parts and Accessories Associate

Mark began working at Thunder Mountain in 2007. Mark’s passion for Harleys began in junior high after he rode on the back of his cousin’s bike during a family reunion. In 2006, his dream came true when he bought a FXDI and it introduced him to a whole new world of riding. He lowered the rear, blacked it out, added drag bars, a stripper seat, under drive pulley, Vance and Hines Black Side Shots, black forward controls, an ‘09 Street Bob rear fender and Black Sparto style tail light. Mark enjoys anything mechanical or electrical and is one of our “go-to’s” for many of our technical problems in the building!
