Harley-Davidson Sportster S vs Honda Forza 250

The Harley-Davidson Sportster S (2025) and the Honda Forza 250 (2026) 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 Harley-Davidson Sportster S is a cruiser with 1,252 cc, 120.7 hp and 228 kg; the Honda Forza 250 is a scooter with 249 cc, 22.8 hp and 186 kg. Power-to-weight with the rider: 398.3 hp/ton versus 87.4 hp/ton. On this measure the Harley-Davidson Sportster S is 356% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the Honda Forza 250 in 10.05 s; the Harley-Davidson Sportster S is quicker by 7.08 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Harley-Davidson Sportster S (with ABS) and 45.2 m for the Honda Forza 250 (with ABS). The Harley-Davidson Sportster S stops 0.5 m shorter. Calculated top speed: 194 km/h (manufacturer claim) versus 124 km/h (GPS measurement).
