F 800 R (K73-2)

Reliable Character, Surprising Range

The Machine's Character

BMW built the F 800 R around a liquid-cooled 798 cc parallel twin making 90 hp and 63 lb-ft, and its character sits closer to cultivated than feral. The upside-down fork and light chassis give it an honest, quick-steering feel, while the flat-sweep bars set a genuine streetfighter posture instead of a polite roadster one. Optional Electronic Suspension Adjustment (ESA) and ride modes let you shift the personality from soft-and-easy to genuinely sharp. In a class that often chases raw noise and drama, this one plants its flag on competence: approachable, well-sorted, and built to a standard you feel in every control.

It ages the way BMWs tend to, with strong reliability and low running costs behind roughly 45 mpg and a chain final drive that keeps upkeep simple. Five seat-height configurations mean most riders find their fit without spending on aftermarket parts, and the bike stays open to both newcomers and seasoned hands rather than narrowing to one target rider. The honest caveat: leave it in its softest setting and the chassis feels vague through a corner, and low-speed running can go jerky around town until you learn to feather the clutch. Sort those, and you have a middleweight that commutes Monday and carves Sunday.

The Voice of Experience

Portrait of NastyNils

The test ride

Throw a leg over and the riding position states the intent right away: wide flat bars, raised elbows, your weight pushed toward the front wheel. You sit in this bike with an assertive, planted feel that reads bigger than 798 cc on paper. The parallel twin is smooth and easy to meter in traffic, tractable enough to trickle through city blocks without fuss, then it wakes up with real pull and a bit of grit once the road opens. What stood out over a full day is how little it wears on you. The bars fall to hand naturally, the reach stays neutral, and there's none of the nervous edginess some middleweights carry. Bolt on the optional rack and the whole thing quietly turns into a tourer without ever feeling like a compromise in either direction.

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.

There's real spread between the modes here, and it tripped me up on my first stint. The chassis felt loose and shapeless through the middle of every corner, with no clear line to lean on. Turned out the previous rider had left it in the softest setting. One click firmer cleaned the whole thing up instantly: the steering woke, it settled through the arc, and the vagueness was gone. The chassis was never the problem, just where the dial was left.

What I keep coming back to is how refined it stays without going flat. Plenty of motors get polished until there's nothing left to feel underneath you; this twin holds smooth and easy to modulate at city pace, then finds enough shove and grain on a climbing road to keep me reading the throttle. It never turns aggressive, and it never fades into the background either. That balance is harder to build than a headline peak, and this one gets there.

The handlebar sets the whole tone. It's wide and close to flat, lifting your arms and pushing your shoulders out ahead of the front wheel, so you sit in an alert, working posture instead of a laid-back cruise. That's streetfighter, not mild roadster. What caught me off guard is the heft it hands you; from up there the bike feels weightier and more deliberate under you than its displacement suggests on paper, and it won me over the second I sat down.

What keeps this one genuinely livable is range. The five seat configurations mean a short rider and a tall one can both get comfortable without spending a cent on parts, and I respect that BMW left the door open here rather than narrowing the bike to a single target rider. Bolt on the optional rack and it hauls enough to travel for real; take it back off and nothing awkward stays behind. Few middleweights stretch this wide.

The Truth on the Street

Over the years I've kept a running tally of what owners tell me: questions after ride-outs, notes from people who've lived with one, and the steady trickle of rider mail. Put it all together and the picture holds firm. This is a bike people are quietly satisfied with, praised most for how it goes and stops, with a short list of complaints that keep coming back.

Where the compliments land

Two things dominate what riders volunteer: the motor and the way it turns. The twin gets called eager and even in its manners, happy to build through the middle revs while staying gentle enough for daily use. Owners like how neatly it changes direction and how relaxed it feels threading through town. Economy near 45 mpg is a regular talking point, and long-run dependability plus strong, well-judged brakes round out the good news.

The gripes that keep surfacing

The negatives are shorter and consistent. Most often riders flag vibration once the engine spins up, felt through the contact points and turning wearisome on long highway stints. Some feel the character stays too tame, effective without much play in it. The front forks draw fire for offering nothing to adjust when weight or taste shifts, and a handful of taller riders find the cockpit tight.

Known issues

  • Rear reflector visibility recall (US)

    bodywork rare Recall

    On 2015-2016 US models, the rear side reflex reflectors may be obscured, failing FMVSS 108. Dealers reposition the reflectors free of charge.

  • Indicator switch failure

    electrics occasional

    A few owners report the left-hand indicator switch becoming intermittent or failing, typically replaced under warranty.

  • Rough low-speed engine running

    engine occasional

    Some riders experience jerky throttle response or uneven idle at low speeds, especially around 25–40 mph (40–65 km/h), which can be mitigated by clutch feathering.

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 F 800 R. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
