 We're Off the Grid (Temporarily) — Back October 15, 2025 ️


Webstore Closed While We Ride Europe!


Hey Selkirk fam,
We're pressing pause on our webstore through October 15, 2025—and for good reason.  Marc & Monica are trading Snowbikes for ADV Bikes and chasing a dream that’s been revving in the background for years: a two-wheeled road trip through Europe.


This isn’t just any trip. We’re talking about epic scenery and legendary roads. First, we hit Germany—a proper moto launch pad. Then it’s up to The Netherlands, for the unexpected gems: winding dike roads, medieval towns stitched together with scenic detours, and just enough curves to keep us leaning and grinning. From there, we’re winding through Scotland’s jaw-dropping North Coast 500, past lochs, cliffs, and a few sheep-dodging moments. Oh, and castles. Lots of castles. Some ancient, some haunted, all badass.


We’ll then cruise through the UK countryside, making our way to the iconic Isle of Man for the 2025 TT Races, the ultimate celebration of speed, courage, and throttle control.


While we're out there making memories, we won’t be fulfilling orders. Our webstore will be offline until October 15, but we’ll still be active—sharing photos, stories, and pit stops from the road. You’ll find it all on @selkirksmx, where we’ll be keeping the community looped in on every twist, turn, and castle climb.


We know it’s a bit of a shift, but this adventure fuels the same spirit that drives Selkirk SMX—freedom, grit, and a bit of madness. We’ll come back with fresh perspectives, new ideas, and maybe a few more stickers on the panniers.


Thanks for riding with us, literally and figuratively. We’ll see you this fall with even more to fuel your winter rides.


Stay wild!
Marc & Monica
