In 1968, before Easy Rider (the movie), Easyriders (the magazine), $1.90 premium, and everything Evo, a couple of Kansas Harley riders named Bonnie Truett and Paul Osborn decided what Wichita, U.S.A. really needed was more cubic inches for their Sportsters. Since then, with more than 40 years and over 15,000 installed sets, Truett & Osborn flywheels haven’t failed once, even in the blistering conditions of top fuel. Truett & Osborn Cycle believes fast equals best. And because of that, our shop in the heartland isn’t about engraved this and billet that. Truett & Osborn is a performance shop established, owned and operated by racers. At Truett & Osborn, the business is speed, the product is horsepower, and our work is to make more of it than anyone else. And for over 40 years, we have been doing just that.
