Suzuki GSX-S1000GX vs Yamaha R25

The Suzuki GSX-S1000GX (2025) and the Yamaha R25 (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 Suzuki GSX-S1000GX is a touring bike with 999 cc, 150.2 hp and unlisted weight; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 485.4 hp/ton versus 145.1 hp/ton. On this measure the Suzuki GSX-S1000GX is 235% ahead.

In the simulation the Suzuki GSX-S1000GX covers 0-100 km/h (speedometer) in 2.94 s and the Yamaha R25 in 6.40 s; the Suzuki GSX-S1000GX is quicker by 3.46 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 45.0 m for the Suzuki GSX-S1000GX (ABS unknown, class assumption: no ABS) and 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 5.0 m shorter. Calculated top speed: 217 km/h (estimated from power and drag) versus 158 km/h (GPS measurement).

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.
