RKS RZ125 vs Suzuki V-Strom 800 DE

The RKS RZ125 (2026) and the Suzuki V-Strom 800 DE (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 RKS RZ125 is a sport bike with 125 cc, 14.5 hp and unlisted weight; the Suzuki V-Strom 800 DE is a adventure bike with 776 cc, 83.1 hp and unlisted weight. Power-to-weight with the rider: 63.8 hp/ton versus 282.1 hp/ton. On this measure the Suzuki V-Strom 800 DE is 342% ahead.

In the simulation the RKS RZ125 covers 0-100 km/h (speedometer) in 13.42 s and the Suzuki V-Strom 800 DE in 3.49 s; the Suzuki V-Strom 800 DE is quicker by 9.92 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 36.4 m for the RKS RZ125 (with ABS) and 41.4 m for the Suzuki V-Strom 800 DE (with ABS). The RKS RZ125 stops 5.0 m shorter. Calculated top speed: 125 km/h (estimated from power and drag) versus 190 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 RKS RZ125 and model-specific parameters calibrated against published road tests for the Suzuki V-Strom 800 DE. 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.
