Boxer Soul With Modern Manners
The R 12 S is BMW building a roadster around a shape first, then making the engineering hold it up. The 1170 cc air/oil-cooled boxer makes 109 hp and 85 lb-ft, and it does its real work early, feeding through a shaft drive with low-rev authority. The bikini fairing is not decoration; it manages air cleanly instead of sealing you off from the road. Under the Lava Orange paint, billet wheels and polished aluminum sits a full electronics package: ABS, traction control, ride modes, cruise control, heated grips, and suspension you can adjust at both ends.
It rides best on roads with a rhythm. Long sweepers, a steady pace, the boxer pulling from just off idle. At 483 lb this is real weight, but the 31.1 in seat and the low center of gravity keep it manageable, and it stays planted when the speed climbs. Build quality and reliability sit where they should for a bike people buy to keep for years. It suits riders who want presence and a strong bottom end more than a spec-sheet win. The honest caveat is heat and a gearbox that lets you know when you rushed it.
Spec sheets don't ride bikes, but they set the baseline.

Start it and the bike rocks once on its mounts, the way a boxer always announces itself. From cold it is lumpy for the first few miles, and you feel that in the bars before you feel it anywhere else. Once it comes up to temperature the vibration settles into a low mechanical hum you notice through the pegs more than through your hands. The riding position is neutral, wrists lightly loaded, the cylinder heads sitting out in your peripheral vision the whole ride. The fairing pushes air over your shoulders and leaves a clean pocket at chest height, so an hour on the interstate doesn't turn into a neck workout. On a warm day in stop-and-go the heat off those cylinders finds your calves. The shifter wants a deliberate boot, and it tells you when it didn't get one.
What follows isn't a test note of mine. It's the sum of what riders have told me over the years, in paddock conversations and club-night chatter, and in the messages owners send once they've lived with a bike a while. On the R 12 S the community lands in a consistent place: real warmth for how it looks and how it moves, alongside a short list of gripes that come up again and again.
The look draws the first comments. Riders talk about the Lava Orange paint, the billet wheels and the milled Option 719 parts as a package that reads expensive up close and gets noticed everywhere else. Running costs surprise them too. Owners report averaging around 46 mpg US (5.1 L/100km) from a motor this size, which makes longer days out cheaper than they expected.
The drivetrain is the one riders raise most often. False neutrals, clunky engagement, and now and then a fight to find first, usually when they're pressing on. After that comes storage: owners say the tight styling leaves nowhere to stash even a small tool roll or their paperwork, which costs the bike some everyday usefulness.
Drivetrain clunkiness and false neutrals
The gearbox can miss shifts and produce loud clunks, especially when shifting quickly or under load. False neutrals occur sporadically between 4th, 5th, and 6th gears.
Radiated engine heat in warm weather
The engine emits significant heat onto the rider's legs and lower body, making riding uncomfortable on hot days or in slow traffic.
Cold-engine roughness
When first started, the engine runs roughly and may hesitate until it reaches operating temperature after about 10 minutes of riding.

Forget spec-sheet bragging. Here's who the R 12 S is actually built for.
Tight, technical repetition is not where 483 lb of boxer shines. On the Cherohala and the Blue Ridge, where corners open up and flow, it is genuinely good company for a long day.
Made for Back of the Dragon · Blue Ridge Parkway · Cherohala Skyway
Angeles Crest suits it, provided you ride smooth and committed rather than chasing outright pace. If you want a light, sharp tool for canyon Sundays, look elsewhere.
Made for Angeles Crest Highway · Coronado Trail / US 191 · Highway 1 / Big Sur
Hill Country was made for this bike. Long flowing roads, torque from just above idle, 46 mpg, and something people walk over to look at when you stop for barbecue.
Made for Austin / Texas Hill Country · Twisted Sisters · Austin / Handbuilt Motorcycle Show
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 S. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
