Kawasaki Eliminator 500 vs RKS RZ125

The Kawasaki Eliminator 500 (2026) and the RKS RZ125 (2026) 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 Kawasaki Eliminator 500 is a cruiser with 451 cc, 44.8 hp and 176 kg; the RKS RZ125 is a sport bike with 125 cc, 14.5 hp and unlisted weight. Power-to-weight with the rider: 178.4 hp/ton versus 63.8 hp/ton. On this measure the Kawasaki Eliminator 500 is 180% ahead.

In the simulation the Kawasaki Eliminator 500 covers 0-100 km/h (speedometer) in 4.66 s and the RKS RZ125 in 13.42 s; the Kawasaki Eliminator 500 is quicker by 8.75 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Kawasaki Eliminator 500 (with ABS) and 36.4 m for the RKS RZ125 (with ABS). The RKS RZ125 stops 8.3 m shorter. Calculated top speed: 163 km/h (manufacturer claim) versus 125 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 Kawasaki Eliminator 500 and class-average calibration (no accepted model-specific road test) for the RKS RZ125.
