Harley-Davidson Nightster Special vs Suzuki GSX-S1000GX

The Harley-Davidson Nightster Special (2025) and the Suzuki GSX-S1000GX (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 Nightster Special is a cruiser with 975 cc, 88.5 hp and 225 kg; the Suzuki GSX-S1000GX is a touring bike with 999 cc, 150.2 hp and unlisted weight. Power-to-weight with the rider: 295.0 hp/ton versus 485.4 hp/ton. On this measure the Suzuki GSX-S1000GX is 65% ahead.

In the simulation the Harley-Davidson Nightster Special covers 0-100 km/h (speedometer) in 3.17 s and the Suzuki GSX-S1000GX in 2.94 s; the Suzuki GSX-S1000GX is quicker by 0.23 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 Nightster Special (ABS unknown, class assumption: no ABS) and 45.0 m for the Suzuki GSX-S1000GX (ABS unknown, class assumption: no ABS). The Suzuki GSX-S1000GX stops 4.1 m shorter. Calculated top speed: 180 km/h (estimated from power and drag) versus 217 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 both. 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.
