Harley-Davidson Sportster S vs Honda Wave RSX FI

The Harley-Davidson Sportster S (2025) and the Honda Wave RSX FI (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 Wave RSX FI is a cub / underbone with 109 cc, 8.7 hp and unlisted weight. Power-to-weight with the rider: 398.3 hp/ton versus 49.5 hp/ton. On this measure the Harley-Davidson Sportster S is 704% ahead.

0-100 km/h (speedometer): Harley-Davidson Sportster S 2.97 s, Honda Wave RSX FI not reached (top simulated speed 88 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 16.1 m for the Harley-Davidson Sportster S (with ABS) and 18.5 m for the Honda Wave RSX FI (ABS unknown, class assumption: no ABS). The Harley-Davidson Sportster S stops 2.4 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 194 km/h (manufacturer claim) versus 88 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 Wave RSX FI. Missing manufacturer data (weight) is estimated by class regression, not measured. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
