Harley-Davidson Low Rider S vs Harley-Davidson Sportster S

The Harley-Davidson Low Rider S (2025) and the Harley-Davidson Sportster S (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 Harley-Davidson Low Rider S is a cruiser with 1,923 cc, 114.0 hp and 304 kg; the Harley-Davidson Sportster S is a cruiser with 1,252 cc, 120.7 hp and 228 kg. Power-to-weight with the rider: 300.8 hp/ton versus 398.3 hp/ton. On this measure the Harley-Davidson Sportster S is 32% ahead.

In the simulation the Harley-Davidson Low Rider S covers 0-100 km/h (speedometer) in 3.69 s and the Harley-Davidson Sportster S in 2.97 s; the Harley-Davidson Sportster S is quicker by 0.72 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 49.1 m for the Harley-Davidson Low Rider S (ABS unknown, class assumption: no ABS) and 44.7 m for the Harley-Davidson Sportster S (with ABS). The Harley-Davidson Sportster S stops 4.4 m shorter. Calculated top speed: 208 km/h (estimated from power and drag) versus 194 km/h (manufacturer claim).

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 the Harley-Davidson Low Rider S and model-specific parameters calibrated against published road tests for the Harley-Davidson Sportster S.
