Blunt motocross testing from the trackside grind.
Rocky Mountain ATV/MC Keefer Tested mixes hands-on bike reviews, racing recaps, listener questions, and long sponsor reads. It is loose and opinionated, but the useful parts land hard: suspension feel, engine character, track conditions, and what actually changes on a bike.
PRESS PLAY
Rocky Mountain ATV/MC Keefer Tested is a long-running motocross show centered on testing, setup, parts, gear, and the weekly life around racing. It is plainspoken. The show often begins with sponsor business and audience housekeeping, then drifts through jokes, family updates, and trackside stories before landing on the mechanical point that matters. That rhythm gives it a lived-in feel. Recent episodes cover KTM and Kawasaki comparisons, a Pro Circuit KX450 Stage One build, a 2026 450 MX non-shootout, a KTM 450 Factory Edition review, SMX Next weekends, Loretta Lynn area qualifiers, and listener questions. The technical detail is strongest when the talk gets physical. Suspension is not treated as a spec sheet. It is described through side-to-side movement, decel feel, fork comfort, spring rates, rough corners, and whether a bike settles down when a rider changes the setup. Race recaps have the same texture. Birmingham and Daytona episodes move through Aiden Kiefer’s SMX Next weekends, family logistics, track timing, pit observations, crashes, starting-line habits, and the odd little details that formal coverage usually misses. The show is also comfortable being messy. Sponsor reads are frequent, jokes run long, and conversations sometimes wander before they return to the point. For the right listener, that looseness is useful rather than distracting. It makes the verdicts feel earned, because the opinions come from testing bikes, hauling to races, watching kids ride, and dealing with the same parts-and-setup questions regular motocross families care about. It is best for riders who want direct experience over polished neutrality. The tone can be blunt and irreverent, but the underlying promise is simple: tell the truth about how the bike, part, race, or weekend actually felt.
Made for: Built for motocross riders, racing families, gear obsessives, and listeners who care about how bikes feel under real conditions. It especially suits people who enjoy setup talk, race-weekend stories, and unvarnished opinions.
What sets it apart: The show’s edge is its combination of concrete test feedback and loose pit-life conversation. It can ramble through sponsors and jokes, then deliver a usable takeaway about suspension, engine feel, bike setup, or race conditions.
Kris Keefer puts bikes, gear, accessories, hard parts... you name it, through the paces to bring you the straight verdict.
