Highside/Lowside - A Motorcycle Podcast

The $6,000 Harley-Davidson, Honda's automatic clutch, the "vicious" KTM 990 RC R superbike, and much, much more are discussed as Zack and Spurg preview the most exciting motorcycles, tech, and industry shifts coming in 2026!
We also have an "Am I the A-hole" debate involving a delivery robot and a parked Harley… and we're joined by gear expert Pat McHugh to discuss the future of hearing protection: Cardo's active noise-canceling helmet.

The legendary Ryan from FortNine drops in to go deep into his most ambitious project yet: a feature-length documentary chronicling a record-breaking, 16-day motorcycle trip around the entire world.
With Zack Courts still out on the mend, Spurgeon Dunbar is joined by CTXP producer Spenser Robert to ask Ryan about his chaotic time in India, the freezing "Nullarbor" of Australia, the logistical miracles worked by Ducati fixers at the Turkish border, and what it's really like to live on a bike for 24+ hours at a time.
