Harley-Davidson Breakout vs Suzuki GSX-S1000GX

The Harley-Davidson Breakout (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 Breakout is a cruiser with 1,923 cc, 103.3 hp and 309 kg; the Suzuki GSX-S1000GX is a touring bike with 999 cc, 150.2 hp and unlisted weight. Power-to-weight with the rider: 268.9 hp/ton versus 485.4 hp/ton. On this measure the Suzuki GSX-S1000GX is 80% ahead.

In the simulation the Harley-Davidson Breakout covers 0-100 km/h (speedometer) in 3.50 s and the Suzuki GSX-S1000GX in 2.94 s; the Suzuki GSX-S1000GX is quicker by 0.56 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 Breakout (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: 202 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 class-average calibration (no accepted model-specific road test) for the Harley-Davidson Breakout and model-specific parameters calibrated against published road tests for the Suzuki GSX-S1000GX. 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.
