Arora Beatrix 150 vs Harley-Davidson Fat Boy

The Arora Beatrix 150 (2026) and the Harley-Davidson Fat Boy (2025) are compared with the same Moto Kıyas physics model under identical conditions: flat dry asphalt, no wind, a 75 kg rider and no passenger. The Arora Beatrix 150 is a scooter with 150 cc, 11.3 hp and unlisted weight; the Harley-Davidson Fat Boy is a cruiser with 1,923 cc, 103.3 hp and 315 kg. Power-to-weight with the rider: 52.8 hp/ton versus 264.8 hp/ton. On this measure the Harley-Davidson Fat Boy is 402% ahead.

0-100 km/h (speedometer): Arora Beatrix 150 not reached (top simulated speed 89 km/h), Harley-Davidson Fat Boy 3.54 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Arora Beatrix 150 (ABS unknown, class assumption: no ABS) and 17.7 m for the Harley-Davidson Fat Boy (ABS unknown, class assumption: no ABS). The Harley-Davidson Fat Boy stops 0.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 89 km/h (estimated from power and drag) versus 201 km/h (estimated from power and drag).

All values are an estimated simulation, not road-test measurements. Technical data comes from the sources listed below; the model uses class-average calibration (no accepted model-specific road test) for both.
