R 12 G/S (KR2)

Raw Boxer, Barely Tamed

The Machine's Character

The R 12 G/S wraps a deliberate statement around the air/oil-cooled 1170 cc boxer: 109 hp, 85 lb-ft, a 21-inch spoked front wheel, an upside-down fork, and a shaft-driven Paralever rear. This is the off-road-minded machine in the Heritage line, and it shows in the upright stance and the Dakar-era styling. BMW Ride Modes Pro, Integral ABS Pro, and traction control run the electronics without smothering the bike's voice. It scores high on character and off-road looks because it earns both honestly, not through a marketing layer laid over an ordinary platform.

On the road it rides like a bike that trusts you to do the work. The boxer pulls hard from low in the rev range, the build quality and reliability feel made to last, and the narrow chassis falls into corners with real intent. But this is a focused tool, not a soft all-rounder. The suspension is firm and fixed, it stands taller and weighs more than the photos suggest, and the raw engine asks for genuine discipline through braking and corner exits. Riders who want a characterful, honest adventure bike and accept those trade-offs will love it. Anyone after effortless, electronically smoothed touring will not.

The Voice of Experience

Portrait of NastyNils

The test ride

Swing a leg over and the first surprise is physical: this feels bigger and taller in a parking lot than any photo prepares you for, and slow maneuvers want your full attention. The seat looks like a token effort but actually carries you through longer days. Out on the road the wide bars are the story. On a short blast the vibration through them reads as character; a few hours in, it becomes something your hands are actively managing. The footpeg edges catch your calves when you walk the bike around, a small thing that compounds across a riding season. You sit fully upright in the wind with almost nothing to hide behind, so a relaxed grip pays off, and at a steady highway pace the boxer settles underneath you and just covers ground.

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.

What I keep coming back to is how little this motor hides. Skip the throttle blip on the way down and the back wheel bites in hard, no software stepping in to soften the handoff, just the engine being honest about what is happening underneath me. Yet open it up to a steady cruising pace and it smooths right out, no fidgeting, no nagging, content to rack up distance. One engine, two completely different moods, and it reads the moment right every time.

The slim spoked front end gives me a turn-in I trust completely through any single bend; I think about the corner and the bike is already leaning, and I stop second-guessing it inside the first few miles. The preload dial earns a word too, sitting right where my hand falls without spoiling the line of the bike. The honesty stops there. String together fast left-rights and that same eager front turns stubborn on me, so I set up each change early rather than flick cleanly between them. The chassis underneath is firm and fixed, which reads clean and locked down on good surfaces but punishes me over broken pavement, where I just soak up the hits and wait for smoother ground. Push hard and hold the pace and the calm leaks away, leaving me working to keep it settled instead of leaning on it.

BMW clearly put real effort into the saddle even though it looks like a throwaway, and that work pays off once the day stretches long. From there the comfort story gets harder. The wide bars channel the engine's vibration straight into my grip; fine on a short hop, but a few hours in it turns into something my hands keep working against. The bike also carries more mass and stands taller than any image lets on, and with nothing on board to drop the seat for me, shorter riders sit right at their reach limit and every low-speed shuffle wants full focus. Then there are the footpeg edges, which keep catching my calves whenever I walk it through a parking lot. On its own that is trivial, but it nags a little more each ride until a full season makes it genuinely tiresome.

Find a tight, winding road and this bike flips a switch in me. It stirs up a genuine appetite to carry more speed and attack every bend like the outcome counts for something. Most polished machines slowly bleed that instinct out of you until even a great road feels like errand-running. This one refuses to let that happen, and it puts the hunger back in my hands. For a certain rider that alone justifies it.

As a load-carrier it actually delivers. Fit the optional top case and it will take two full-face helmets plus a complete camera kit without protest, so capacity is never the issue. The issue is what that hardware does to the bike. This thing was built as a statement, not a pack mule, and every bracket and case I bolt on quietly drains the character that makes it worth owning, with no real way to win it back.

Best touring motorcycle for long distance?

Big interstate days are where this bike fights you: firm suspension, buzzy bars, and no real wind protection make long stints work. It can tour, but loaded two-up comfort isn't its calling.

Best motorcycle for Moab?

The 21-inch front, 9.4 inches of clearance, and real travel give it genuine dirt credibility. Just respect the 505 lb wet weight and tall seat on technical sections; this rewards skill, not brute force.

Best motorcycle for Highway 1?

This is close to your sweet spot: eager turn-in, strong low-end pull, and a character that makes you push every corner. Stick to smooth roads, since the firm setup punishes broken pavement on a long day.

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.
