Kuba Superlight 125 vs Yamaha Tracer 9

The Kuba Superlight 125 (2026) and the Yamaha Tracer 9 (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 Kuba Superlight 125 is a cruiser with 124 cc, 10.5 hp and unlisted weight; the Yamaha Tracer 9 is a touring bike with 890 cc, 117.3 hp and 219 kg. Power-to-weight with the rider: 42.5 hp/ton versus 399.1 hp/ton. On this measure the Yamaha Tracer 9 is 840% ahead.

0-100 km/h (speedometer): Kuba Superlight 125 not reached (top simulated speed 91 km/h), Yamaha Tracer 9 2.95 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.7 m for the Kuba Superlight 125 (ABS unknown, class assumption: no ABS) and 16.2 m for the Yamaha Tracer 9 (ABS unknown, class assumption: no ABS). The Yamaha Tracer 9 stops 1.5 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 90 km/h (estimated from power and drag) versus 215 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 Kuba Superlight 125 and model-specific parameters calibrated against published road tests for the Yamaha Tracer 9.
