BMW F 450 RR vs Rivals: Engine and Performance
BMW delivers the highest peak power, while Aprilia leads on torque
| Specification | BMW F 450 RR | Kawasaki Ninja 500 | Aprilia RS 457 |
|---|---|---|---|
| Engine | 420cc, twin-cylinder, liquid-cooled | 451cc, twin-cylinder, liquid-cooled | 457cc, twin-cylinder, liquid-cooled |
| Maximum Power | 48hp at 8,750rpm | 45.41hp at 9,000rpm | 47.6hp at 9,400rpm |
| Maximum Torque | 43Nm at 6,750rpm | 42.6Nm at 6,000rpm | 43.5Nm at 6,700rpm |
| Gearbox | 6-speed | 6-speed | 6-speed |
| Power-to-weight ratio | 270hp/tonne | 252hp/tonne | 272hp/tonne |
The BMW F 450 RR uses a 420cc, liquid-cooled parallel-twin engine that produces 48hp at 8,750rpm and 43Nm at 6,750rpm. The powertrain also features a 135-degree crankpin offset and a balance shaft. BMW has retained the engine’s core output figures while adapting the motorcycle for a fully-faired supersport role.
The Kawasaki Ninja 500 gets a larger 451cc engine, producing 45.41hp and 42.6Nm. The Aprilia RS 457 uses the largest engine of this trio at 457cc, generating 47.6hp and 43.5Nm.
On paper, the BMW has the highest peak power, while the Aprilia delivers the most torque and has the highest listed power-to-weight ratio. However, these figures alone do not establish which motorcycle is quicker or offers better real-world performance. Riding conditions, gearing and chassis behaviour will also influence the experience.
BMW F 450 RR vs Rivals: Dimensions and Weight
Kawasaki offers the lowest seat height among the three
| Specification | BMW F 450 RR | Kawasaki Ninja 500 | Aprilia RS 457 |
|---|---|---|---|
| Fuel Tank Capacity | 14 litres | 14 litres | 13 litres |
| Ground Clearance | Not available | 145mm | Not available |
| Kerb Weight | 178kg | 176kg | 175kg |
| Seat Height | 790mm | 785mm | 800mm |
| Wheelbase | 1,405mm | 1,375mm | Not available |
The Kawasaki Ninja 500 has the lowest standard seat height at 785mm, making it the most accessible option on paper for riders who prefer a lower saddle. It also has a 14-litre fuel tank, matching the BMW, while the Aprilia has a slightly smaller 13-litre tank.
The BMW F 450 RR has a standard seat height of 790mm. Buyers can also choose an optional low seat that reduces it to 775mm or a sport seat that raises it to 810mm. These options give riders some flexibility when selecting their preferred riding position.
At 800mm, the Aprilia RS 457 has the tallest standard seat height among the three. Its listed kerb weight of 175kg is also the lowest of this comparison, narrowly ahead of the Kawasaki at 176kg and the BMW at 178kg.
The available figures do not include ground clearance for the BMW and Aprilia or the Aprilia’s wheelbase. These specifications have therefore not been estimated.

BMW F 450 RR vs Rivals: Tyres, Brakes and Suspension
BMW and Aprilia use upside-down front forks
| Specification | BMW F 450 RR | Kawasaki Ninja 500 | Aprilia RS 457 |
|---|---|---|---|
| Front Tyre | 110/70 R17 | 110/70 R17 | 110/70 R17 |
| Rear Tyre | 150/60 R17 | 150/60 R17 | 150/60 R17 |
| Front Brake | 310mm disc | 310mm disc | 320mm disc |
| Rear Brake | 240mm disc | 220mm disc | 220mm disc |
| Front Suspension | USD fork | Telescopic fork | USD fork |
| Rear Suspension | Monoshock | Monoshock | Monoshock |
| ABS | Dual-channel | Dual-channel | Dual-channel |
All three motorcycles use 17-inch alloy wheels with the same listed tyre sizes: 110/70 R17 at the front and 150/60 R17 at the rear. Their suspension and braking hardware, however, differ.
The BMW F 450 RR gets a 43mm upside-down front fork, with optional rebound and compression damping adjustment. Its rear monoshock offers preload and rebound adjustment. The Aprilia RS 457 uses a 41mm preload-adjustable USD fork, paired with a preload-adjustable rear monoshock.
The Kawasaki Ninja 500 takes a simpler approach with a 41mm telescopic front fork and a preload-adjustable rear monoshock. Riders looking for an upside-down front fork will therefore find that the BMW and Aprilia offer that setup.
For braking, the Aprilia has the largest front disc at 320mm, while the BMW and Kawasaki use 310mm front discs. The BMW also gets a larger 240mm rear disc, compared with the 220mm units on the other two motorcycles. All three come with dual-channel ABS as standard.
Disc size and suspension specifications provide a useful starting point for comparison, but braking feel, suspension tuning and overall control can only be judged properly through a riding assessment.
BMW F 450 RR vs Rivals: Features and Electronics
BMW offers the most extensive feature package on paper
The BMW F 450 RR stands out with its range of electronic features and optional equipment. Depending on the variant and package, it offers configurable riding modes, lean-sensitive ABS, traction control, a bidirectional quickshifter and the optional Easy Ride Clutch system. It also gets a 6.5-inch TFT instrument display with smartphone connectivity and turn-by-turn navigation.
The Easy Ride Clutch is an optional feature rather than standard equipment across the entire range. Buyers will need to check the specific variant and package to understand which features are included.
The Aprilia RS 457 comes with three riding modes and three levels of traction control. A bidirectional quickshifter is available as an option, while its 5-inch TFT display offers Bluetooth connectivity and turn-by-turn navigation.
The Kawasaki Ninja 500 has a simpler equipment list. The India-spec model gets an LCD instrument cluster, LED lighting, dual-channel ABS and an assist-and-slipper clutch. It does not offer riding modes, traction control or a quickshifter according to the specifications used for this comparison.
For riders who prioritise electronic rider aids and a modern instrument display, the BMW and Aprilia have an advantage on paper. The Kawasaki’s simpler setup may appeal to buyers who prefer a more straightforward motorcycle, although the final decision should also consider pricing, ownership costs and intended use.
BMW F 450 RR vs Rivals: Which Motorcycle Looks Better on Paper?
The BMW F 450 RR, Kawasaki Ninja 500 and Aprilia RS 457 approach the supersport category differently.
The BMW leads in peak power and offers adjustable suspension options, a larger rear brake disc and an extensive electronics package. The Kawasaki has the lowest standard seat height and a straightforward mechanical setup. The Aprilia combines the highest listed torque figure with the lowest kerb weight and the highest listed power-to-weight ratio.
There is no single winner across every specification. Riders who prioritise electronic features may favour the BMW, while those who want a lower seat height may find the Kawasaki more approachable. The Aprilia also makes a strong case through its engine output, weight and suspension hardware.
Auto India Daily Verdict
On paper, the BMW F 450 RR looks like a well-equipped new entrant in the twin-cylinder supersport segment. In the BMW F 450 RR vs Rivals comparison, its 48hp output gives it a small power advantage over the Kawasaki Ninja 500 and Aprilia RS 457, while its optional Easy Ride Clutch and adjustable suspension add to its technical appeal.
However, specifications alone cannot determine the best motorcycle. Price, comfort, handling, service support and real-world performance will all influence the final buying decision. BMW has not announced an official India launch timeline or pricing for the F 450 RR, so its competitiveness in the Indian market will become clearer once those details are confirmed.
