Kuba Terra125 vs Yamaha MT-25

The Kuba Terra125 (2026) and the Yamaha MT-25 (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 Terra125 is a naked bike with 125 cc, 9.5 hp and unlisted weight; the Yamaha MT-25 is a naked bike with 250 cc, 35.4 hp and 166 kg. Power-to-weight with the rider: 48.7 hp/ton versus 146.9 hp/ton. On this measure the Yamaha MT-25 is 201% ahead.

0-100 km/h (speedometer): Kuba Terra125 not reached (top simulated speed 89 km/h), Yamaha MT-25 6.35 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.3 m for the Kuba Terra125 (ABS unknown, class assumption: no ABS) and 17.3 m for the Yamaha MT-25 (ABS unknown, class assumption: no ABS). The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 89 km/h (estimated from power and drag) versus 147 km/h (derived (GPS ratio)).

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 Terra125 and model-specific parameters calibrated against published road tests for the Yamaha MT-25.
