BMW Motorrad brings its small-displacement platform to pavement with the BMW F 450 R, a naked motorcycle that borrows S 1000 R styling and the F 450 GS engine architecture. The pitch centers on manageable weight, useful low-rpm torque, and rider assistance that reaches the base model.
A 420cc Twin With Useful Torque
The badge rounds up. The 420cc parallel-twin engine uses liquid cooling, dual overhead camshafts, four valves per cylinder, and a 13:1 compression ratio. BMW quotes 48 hp, or 35 kW, at 8,750 rpm and 31.7 lb-ft of torque at 6,750 rpm.
Specifically, the engine delivers 80% of peak torque at 3,000 rpm: approximately 25.4 lb-ft. That output should reduce downshifting during everyday acceleration, although a road test must establish throttle response and passing performance. A 135-degree crankpin offset creates uneven firing intervals, while a counter-rotating balance shaft reduces vibration.
| Specification | Metric figure | U.S. equivalent |
|---|---|---|
| Bore × stroke | 72 × 51.6 mm | 2.83 × 2.03 inches |
| Road-ready weight | 175 kg | 386 pounds |
| Wheelbase | 1,405 mm | 55.3 inches |
| Front/rear suspension travel | 140/140 mm | 5.51/5.51 inches |
| Standard seat height | 790 mm | 31.1 inches |
| Fuel capacity | 14 liters | 3.70 gallons |
| Claimed 0–100 km/h | 5.7 seconds | 0–62 mph |
| Claimed top speed | 169 km/h | 105 mph |
BMW's 3.8-liter/100-km WMTC consumption figure converts to 61.9 mpg U.S. The company claims over 217 miles of range; highway speeds, wind, and luggage will influence actual results. Scheduled service intervals span 6,214 miles.
Road Geometry and Cornering ABS
BMW uses the engine as a structural member within a tubular steel frame. A 23.4-degree steering-head angle and 4.33-inch trail support the road-focused geometry, while a 43mm KYB inverted fork controls the front wheel. The rear KYB shock offers preload and rebound adjustment.
The braking and equipment package includes:
- Front brake: 310mm/12.2-inch rotor and Brembo four-piston monobloc caliper.
- Rear brake: 240mm/9.45-inch rotor and ByBre single-piston caliper.
- Tires: 110/70-17 front and 150/60-17 rear on cast-aluminum wheels.
- Standard equipment: lean-sensitive ABS Pro, traction control, three riding modes, heated grips, a 6.5-inch TFT, and USB-C charging.
ABS Pro adjusts braking intervention for lean angle. Riders still need adequate tire grip and sensible corner-entry speed.
Four Trims and an Automated Clutch Option
The Easy Ride Clutch uses centrifugal engagement tied to engine speed. Combined with Shift Assistant Pro, it lets riders start, stop, and shift without operating the clutch lever. Riders still select gears, and the lever retains manual control.
| Version | Quickshifter | Adjustable Sport fork | Added equipment |
|---|---|---|---|
| Base | Accessory | No | Core standard package |
| Exclusive | Standard | Yes | Cosmic Black finish |
| M Sport | Standard | Yes | Riding Modes Pro; Motorsport colors |
| M Sport + Innovation Package | Standard | Yes | Easy Ride Clutch |
The clutch preserves engine braking until near standstill, then disengages at idle to prevent stalling.
Should You Put the F 450 R on Your Shortlist?
For commuting, prioritize seat fit and clutch convenience over paint. BMW offers 30.5-, 31.1-, and 31.9-inch seat heights; those choices can improve confidence during parking and stop-and-go riding.
Pro-Tips: Try the seat in riding boots, request a demonstration of low-speed clutch engagement, and compare complete dealer quotes across trims.
