BMW R 1300 GS vs Harley-Davidson Breakout

The BMW R 1300 GS (2024) and the Harley-Davidson Breakout (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 BMW R 1300 GS is a adventure bike with 1,300 cc, 143.5 hp and 237 kg; the Harley-Davidson Breakout is a cruiser with 1,923 cc, 103.3 hp and 309 kg. Power-to-weight with the rider: 459.9 hp/ton versus 268.9 hp/ton. On this measure the BMW R 1300 GS is 71% ahead.

In the simulation the BMW R 1300 GS covers 0-100 km/h (speedometer) in 2.96 s and the Harley-Davidson Breakout in 3.50 s; the BMW R 1300 GS is quicker by 0.54 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.4 m for the BMW R 1300 GS (with ABS) and 49.1 m for the Harley-Davidson Breakout (ABS unknown, class assumption: no ABS). The BMW R 1300 GS stops 7.7 m shorter. Calculated top speed: 225 km/h (manufacturer claim) versus 202 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 BMW R 1300 GS and class-average calibration (no accepted model-specific road test) for the Harley-Davidson Breakout.
