About Us

Harley-Davidson performance, backed by a real Idaho shop

High Desert Performance is a family-owned, independent motorcycle shop in Shelley, Idaho. We work on Harley-Davidson motorcycles and help riders choose parts that suit their bike, riding style, and goals.

Parts, installation, and dyno tuning

Our shop handles routine maintenance, cam upgrades, big bore builds, and dyno tuning. We use a Dynojet 250i to measure performance and tune bikes, and sell parts from brands including S&S Cycle, Dynojet, Arlen Ness, and Bel-Ray.

Planning a build or replacing a part? Start with your motorcycle year, model, engine size, and existing modifications. We can help you check fitment and identify supporting parts before you order.
