R 12 G/S (KR2)

Raw Boxer, Barely Tamed

The Machine's Character

The R 12 G/S is built around the 1170cc air/oil-cooled boxer, an engine that makes 109 hp and 85 lb-ft and never hides its mechanical hand. Drive runs through a shaft and BMW's Paralever, the bike rolls on a 21-inch cross-spoke tubeless front, and a fully upside-down fork carries real travel underneath. The electronics are present but deliberately light: Ride Modes Pro, Integral ABS Pro, traction control. This is BMW building an adventure bike around character first, then wrapping it in the controlled competence the badge always brings. It looks like a Dakar refugee and backs the look with genuine gravel capability.

On the road it feels alive in a way refined machines slowly sand away. The low-end pull is strong, the throttle honest, the front wheel quick to fall into a corner. Reliability and build quality both score well, so it should wear its miles without drama. But this is a firm, fixed-suspension bike with real height and weight, and no electronic aids to soften either. It suits the rider who wants involvement over insulation, who reads a stiff ride and a demanding low-speed manner as the fair price of character. Anyone chasing effortless touring comfort should look harder before buying.

The Voice of Experience

Portrait of NastyNils

The test ride

Swing a leg over in a parking lot and the photos stop lying. It's tall and substantial, the seat height right at the edge for shorter riders, and slow maneuvers ask for your full attention. The saddle looks like an afterthought and turns out to be genuinely comfortable on a long day. Drop a gear without blipping and the rear tire stamps hard, no software stepping in to soften the load. The wide bars read as character on a short blast and as a chore over several hours, buzzing straight into your palms. The aggressive footpeg edges keep finding your calves when you walk it around. Push past a relaxed cruising pace and it gets nervous in the wind, sitting bolt upright while every bit of grip tension feeds the steering. The tool-free preload dial sits right where your hand expects it.

Rated point by point — where it earns its keep

My own 0–100 score for this bike against the class, area by area — the marker on each bar is the class average.

This motor runs two moods and reads the room every time. Come down a gear without the courtesy blip and the rear steps in with a hard, unapologetic thump, zero electronic cushioning between me and the driveline, just honest mechanical weight I'd almost forgotten a motor could deliver. Wind it out to a relaxed highway lope and it turns civil, no droning at a steady throttle, no mechanical griping, content to reel in the miles. The same engine that dares you in the twisties is calm as you like when the job is distance.

The headline is that narrow spoked front. Aim it at an apex and it drops in on the first request, quick and eager, and within a few miles I quit bracing and simply leaned on it. The rear preload dial deserves a nod too, tool-free and falling right under my hand without cluttering the bike's silhouette. Honesty catches up after that. Hold a genuine pace and the calm drains away; sat bolt upright in the airflow, any tightness in my grip writes itself into the steering until holding a line becomes labor. Link fast switchbacks and that willing front turns obstinate, so I plan each transition a beat ahead rather than flick through. And the firm, fixed chassis feels locked and clean on good tarmac yet punishes over broken surfaces, where the ride stops being fun and turns into something to endure.

There's exactly one piece of good news, and it's the saddle. It looks like a parts-bin afterthought and proves to be anything but; the detail work shows once a day runs long. After that, comfort asks for patience. The wide handlebars feed engine tremor into my hands the moment the revs climb; a short hop registers it as texture, but a few hours in my palms are constantly working against it. It's a bigger, taller machine than any photo admits, and with nothing aboard to lower the seat, a shorter rider is stranded on tiptoe while wrangling that mass at walking pace eats real concentration. The sharp peg edges nip my calves every time I duck-walk it, nothing on day one and quietly maddening by season's end. And it never lets me coast; keeping that unfiltered boxer tidy through hard braking into a throttle-on exit is my job alone, the deliberately light electronics leaving that finesse to me.

Point it down a twisting road and something wakes up in me. It breeds a real appetite to carry more corner speed, to treat every bend like it counts, to keep making the move. Most polished bikes slowly wear that instinct down until even a brilliant road feels like an errand. This one hands the hunger straight back. For the right rider, that quality alone carries it.

Bolt on the optional top case and the capacity is genuinely there; it took two full-face lids and a loaded camera bag without a grumble, so hauling is never the problem. What hauling does to the bike is the problem. This machine was drawn as a statement, not a workhorse, and every case and bracket I hang off it quietly siphons away the exact character I'd buy it for, with nothing that fully hands it back.

Best touring motorcycle for long distance?

Great on scenic stretches, but be honest: firm suspension, upright wind exposure, and luggage that fights the bike's whole personality. Better for the route than for all-day two-up comfort.

Best motorcycle for Moab?

The 21-inch front, tubeless cross-spokes, and 9.4 in of clearance give real gravel capability, but the weight and height are real too. Day trips and moderate technical lines suit it better than heavy, all-day sand work.

Made for Bar M / Kane Creek · Imperial Sand Dunes · Johnson Valley OHV Area

Best motorcycle for Highway 1?

This is where it shines: eager turn-in, strong low-end, and a hunger to push through corners. Just plan for buzzy bars and a firm ride on longer days, and keep the pace out of the nervous zone.

Alternatives to the BMW R 12 G/S

If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this BMW R 12 G/S. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
