Who We Are
Built by riders,
for riders.
Big 4 Motorsports isn't a franchise or a corporate chain. We're a local shop in the heart of Coeur D'Alene, built around one simple idea: riders deserve better options.
Whether you're prepping your dirt bike for the singletrack, upgrading your street bike's exhaust, or just looking for a helmet that actually fits — we're here. We stock products we'd put on our own machines, and we tell you which ones to skip.
Our doors are open to everyone from weekend warriors to competitive racers. No judgment, no upselling — just honest recommendations from people who live this stuff.
