Harley-Davidson Sportster S vs Honda NC750X

The Harley-Davidson Sportster S (2025) and the Honda NC750X (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 NC750X is a adventure bike with 745 cc, 57.8 hp and 226 kg. Power-to-weight with the rider: 398.3 hp/ton versus 192.0 hp/ton. On this measure the Harley-Davidson Sportster S is 107% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the Honda NC750X in 4.49 s; the Harley-Davidson Sportster S is quicker by 1.53 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 41.4 m for the Honda NC750X (with ABS). The Honda NC750X stops 3.3 m shorter. Calculated top speed: 194 km/h (manufacturer claim) versus 163 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 model-specific parameters calibrated against published road tests for the Harley-Davidson Sportster S and class-average calibration (no accepted model-specific road test) for the Honda NC750X.
