BMW's F 450 RR brings the RR look to the 48hp class

BMW is bringing its RR family down to the 48hp class. The new F 450 RR wraps a 420cc parallel twin in a full fairing with winglets and styling borrowed from the S 1000 RR. Clip-on bars complete the supersport layout, while a 790mm seat and standard heated grips acknowledge that it will spend plenty of time away from a circuit.

A 420cc twin with its own character

The twin comes from the F 450 GS family, tuned here for the RR. BMW claims 35kW (48hp) at 8,750rpm and 43Nm at 6,750rpm, putting it at Europe's A2 power limit without a restrictor. Its unusual 135-degree crankpin offset gives uneven firing intervals, with a balance shaft to manage vibration. BMW says 80% of peak torque is available from 3,000rpm, so the engine's appeal should extend beyond chasing the top of the rev counter.

The chassis and the fit

Under the bodywork is a tubular steel frame that uses the engine as a load-bearing member, paired with an aluminium double-sided swingarm. A 43mm KYB upside-down fork and KYB rear shock provide 140mm of travel at each end. Both wheels are 17-inch cast items, with a relatively narrow 150/60 rear tyre. Braking is handled by a single 310mm front disc and Brembo four-piston caliper, backed by a 240mm rear disc and standard cornering ABS.

BMW quotes 177kg ready to ride with standard equipment, operating fluids and at least 90% of the usable fuel capacity. The tank holds 14 litres. Riders can also change the standard seat for an accessory option 15mm lower or 20mm higher, giving some room to adjust the fit alongside that sports-bike riding position.

What Sport and M Sport add

The base bike gets a useful amount of kit: Rain, Road and Race modes, traction control, engine drag torque control, LED lighting, a 6.5-inch TFT, USB-C and those heated grips. The rear shock has adjustable preload and rebound damping across the range.

Sport adds the up-and-down quickshifter and fork compression and rebound adjustment. M Sport keeps those upgrades, adds the white M Motorsport colour scheme and introduces Race Pro. That mode lets riders tailor engine response, traction control and ABS, while extra TFT screens show information including lean angle, braking force and lap times.

M Sport can also be ordered with the Innovation Package and Easy Ride Clutch. The centrifugal system handles clutch engagement when pulling away and stopping; paired with the quickshifter, it removes the routine need to use the lever. The rider still changes gear, and the clutch lever remains available. Engine braking is retained on the overrun until the clutch opens near idle. ERC can also be retrofitted to the other versions.

US and European prices

German prices start at €7,250 including VAT, with deliveries expected from June 2027. In the US, BMW advertises $7,815 plus $795 destination, with bikes due in late Q2 2027.
