HP2 Megamoto (K25M)

Boxer Torque With No Apologies

The Machine's Character

The HP2 Megamoto came out of BMW's HP division as a hand-built special, and the parts list shows it. A 1170cc air/oil-cooled boxer makes 113 hp and 85 lb-ft, fed by fuel injection and routed through a shaft drive. Öhlins at the rear, an Akrapovic silencer, and genuine carbon bodywork are all factory rather than optional. There's no Telelever and no ABS to soften the experience. In a class built around small, frantic singles, this is the outlier: a big, charismatic twin that turns supermoto attitude into something heavier and far more exclusive.

It rides lighter than its 439 lb suggests, with torque on tap everywhere and a chassis that commits fast and holds its line. The boxer is the durable member of this engine family; the clutch and valve-cover troubles that hit earlier versions rarely surface here, and routine service stays easy with the cylinders out in the open. It suits a tall rider who wants real-world thrills on a winding road and doesn't mind a thirsty tank or scarce HP-specific parts. At a 35.0 in seat height, solo only, it was never built to fit everyone.

The Voice of Experience

Portrait of NastyNils

The test ride

Throw a leg over and the first thing you negotiate is the height; at 35.0 in you sit up high and every stop takes planning. Fire it up and the boxer has a vocal, mechanical voice that fills your helmet. The cylinders sit wide and low, right at shin level, so you collect bruises learning where they are before your footwork adapts. On a winding road it changes direction with almost no effort through the bars. Crack the throttle hard and the whole bike nudges sideways from the shaft drive, alien at first, then just part of the conversation. The suspension stays firm, planted on smooth pavement and busy once the surface breaks up. And the front wheel lifts more readily than you would ever plan for.

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 makes the difference here isn't obvious until you're leaned over. The wide, flat boxer hangs its mass low in the chassis, and the quality suspension turns that low center of gravity into a bike that never feels like it's wrestling its own weight at the limit. It tips in willingly and then settles onto a line without asking anything of your arms. For a machine this physically substantial, the lightness through a corner is the part that stays with me.

There's no ABS here, and I came to see that as a fair trade. The feel at the lever is outstanding; the brakes tell you exactly where the threshold sits, and once you learn to read it you can sit right on the edge of it. The flip side is real. The front bites hard with no electronic net beneath you, and on an open road that's precisely what you want. Drop into town, with slow traffic and surfaces you can't trust, and it demands measured, deliberate hands rather than a casual grab at the lever.

Twist the throttle from a standstill and it simply hauls. There's no threshold to chase up the tach, no clutch slip to drag it into a sweet spot; the pull is sitting there at every rpm. What surprised me more is how civilized it gets when you back off. Roll the throttle shut and the character softens completely, with clean fueling, a quiet mechanical note, and nothing stumbling when you're trickling along at walking pace. Lazy riding costs you nothing. Because the drive runs through a shaft instead of a chain, nothing sits between your wrist and the rear wheel to soak up the request, so what you ask for arrives with no slack in it. And the mid-range doesn't build, it lands. Open the throttle partway through a corner and the torque comes on abruptly enough that it colors how the bike feels every single time. Ride it once and that punch stays with you.

This is where the bike abandons good sense. The torque arrives sooner than you brace for, so lofting the front on a public road is genuinely doable rather than a track-day trick; the harder part is setting it back down cleanly before things get untidy. Left to its own devices it drags you toward the limit instead of nudging you, and speed cameras became a fixture of my test. Every rational mark against it cancels itself out after one ride. Owners keep theirs not because the math works, but because nothing else feels the way this does.

Look closely and this thing reads less like a production bike and more like a one-off; the finish sits a clear step above what rolls off a normal line, right down to paint that catches your eye before any of the hardware does. Underneath the boutique presentation is an engine I'd trust for the long run. Owners who've stacked up real mileage rarely report the clutch grief or weeping valve covers that troubled earlier takes on this motor, which tells me the factory banked its lessons before it signed this version off. Two things temper that. Ridden the way it begs to be ridden it drinks fast from a tank that was never generous, so fuel stops punctuate the day more than you'd like. And while anything shared with the R1200 range is a phone call away, the bodywork and hardware unique to this build are scarce and pricey on the rare occasion something does let go.

The suspension is where I spent the most time fiddling. Every component is top quality and fully adjustable, but the baseline is firm and it never strays far from that no matter how you set the clickers. On clean pavement at pace it stays composed and planted; let the road surface break up and it passes the whole mess straight to your hands and backside. The other compromise is reach to the ground. Order the low seat and drop the suspension and it's still a long way down, so anyone of average height burns real concentration at every light. What the bike gives back is room. I'm well over six feet and I finally had somewhere to put my legs instead of folding into a crouch built for someone smaller. If the height suits you, the payoff is genuine. If it doesn't, the geometry won't bend to meet you halfway.

I leaned on this as actual transport, not a Sunday-only plaything. It handled city traffic, stood up to commuting duty, and saw out longer group rides without ever becoming a chore to ride. There's one firm limit on its usefulness, and it's deliberate: no passenger pegs at all. The factory built it for a single rider, full stop, so the moment your plans include a second person, you're looking at the wrong bike.

The Truth on the Trail

I've spent years collecting what riders say about this bike, in paddock conversations, long back-and-forth email threads, and the notes people send me straight off their own machines. The pattern that comes back is steady and easy to read. Owners love how it rides and how rare it is, and they grumble about what it asks of them day to day.

What keeps owners hooked

The praise clusters tightly around the boxer and the chassis. Riders consistently describe a strong, revvy twin with a vocal exhaust note that adds theater to every outing. Just as often they talk about a bike that feels lighter than it has any right to, flicking through corners with real confidence. The brakes draw steady admiration for raw power and clean feel, with no electronic net between hand and tire. And many keep coming back to the small-batch build and top-shelf parts, the kind of finish that still turns heads.

Where it asks for patience

The complaints gather around living with it. Shorter riders consistently find the tall seat a stretch, and stops take planning. A recurring gripe is the price, steep when new and stubbornly high secondhand. Owners also note a thirsty engine paired with a small tank, which keeps the range short and the fuel stops frequent. And with no wind protection at all, riders say sustained speed on the open road wears you down fast.

Known issues

  • Fuel pump flange may crack and leak

    fuel systemrareRecall

    NHTSA recall 20V471: The fuel pump flange can crack, causing a fuel leak while the engine is running. Affected units are 2007–2009 Megamotos. Dealers replace the fuel pump assembly.

  • Side stand cut-out switch failures

    electricsoccasional

    The side stand interlock switch can go faulty, causing misfires or cutting the engine. The switch is vulnerable to dirt and foot strikes.

  • Battery drain when parked

    electricsoccasional

    The small battery can discharge quickly if the bike is not used regularly. Owners often fit a battery tender or upgrade to a larger battery.

  • Brake light switch failure

    electricsoccasional

    The brake light (likely the rear switch) stops working. Multiple owners on HP2 forum days reported blown brake lights, and some had repeated failures.
