A supersport BMW with 48 horsepower. Say that out loud and it sounds like a contradiction, but the 2027 F 450 RR M Sport is real, it costs $7,815 before destination, and it’s the only version Americans will get to buy.
BMW Motorrad USA confirmed the bike arrives in summer 2027 wearing the white and M Motorsport livery as standard. The black Base and red Sport trims stay in Europe. American buyers get the top shelf or nothing.
The 420 cc liquid-cooled parallel twin makes exactly 48 hp at 8,750 rpm and 32 lb-ft of torque at 6,750 rpm. Those numbers aren’t accidental. They land precisely at the ceiling of Europe’s A2 motorcycle license, which caps output at 35 kW and restricts the power-to-weight ratio to 0.2 kW/kg.
The RR hits 0.198 kW/kg, just under the wire. It’s a bike engineered to a regulation, then shipped across the Atlantic where that regulation doesn’t exist.
Road-ready weight is 392 lb. BMW quotes 0-62 mph in 5.6 seconds, a 110-mph top speed and 61.9 mpg on the WMTC cycle. The 3.69-gallon tank stretches past 217 miles between fill-ups. Those are commuter numbers dressed in superbike bodywork borrowed directly from the S 1000 RR, complete with winglets, asymmetrical gill panels, and a split-face DRL signature.
Under the skin, the platform is shared with the F 450 GS adventure bike. A welded tubular steel space frame uses the engine as a stressed member. A single 310 mm front disc with a Brembo four-piston monobloc caliper does the stopping.
One rotor, not two. That’s where the budget shows. At the rear, a 240 mm disc with a ByBre single-piston unit backs it up. Lean-sensitive ABS Pro comes standard.
KYB handles both ends of the suspension. The gold-anodized 43 mm inverted fork is adjustable for rebound and compression on the M Sport, and the rear shock gets adjustable preload and rebound. Both offer 5.5 inches of travel. Cast wheels wear 110/70-17 front and 150/60-17 rear rubber.
The electronics package punches well above the displacement. Rain, Road and Race modes are standard. The M Sport adds Race Pro with individually adjustable throttle response, traction control and ABS maps.
Sport screens display lean angle, braking force and a lap timer. Shift Assistant Pro, BMW’s bidirectional quickshifter, is included. So are heated grips, a 6.5-inch TFT with Bluetooth connectivity, LED lighting and USB-C charging.
For $330 more, the Innovation Package adds the Easy Ride Clutch, a centrifugal unit that engages with engine speed. Paired with the quickshifter, the bike can be ridden without ever touching the clutch lever. The lever stays mounted for riders who want manual control. Total ask with the package: $8,145 before destination.
The competitive crosshairs point straight at Aprilia’s RS 457, which makes identical power at 35 kW and weighs six pounds less at 386 lb. Aprilia also offers a full-fairing sportbike at a similar price point, and it doesn’t share its chassis with a dual-sport. But it also doesn’t come with BMW’s electronics depth or the M Sport packaging.
TVS Motor Company builds the F 450 RR in Hosur, India, alongside BMW’s G 310 models and the other new 450s. The previous small-displacement RR in BMW’s portfolio, the G 310 RR, never left Asia. This one does, but only in its most expensive trim, aimed at a market where the A2 license requirement that shaped every engineering decision simply doesn’t apply.
Whether 48 horsepower at eight grand captures American riders who could buy a used 600 cc for less remains the open question. BMW Motorrad is betting on electronics, brand cachet, and that white M Motorsport paint to answer it.
