Kuba Superlight 125 vs Yamaha R7

The Kuba Superlight 125 (2026) and the Yamaha R7 (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 Kuba Superlight 125 is a cruiser with 124 cc, 10.5 hp and unlisted weight; the Yamaha R7 is a sport bike with 689 cc, 72.4 hp and 189 kg. Power-to-weight with the rider: 42.5 hp/ton versus 274.3 hp/ton. On this measure the Yamaha R7 is 546% ahead.

0-100 km/h (speedometer): Kuba Superlight 125 not reached (top simulated speed 91 km/h), Yamaha R7 3.41 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 14.4 m for the Yamaha R7 (ABS unknown, class assumption: no ABS). The Yamaha R7 stops 3.3 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 202 km/h (manufacturer claim).

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 R7.
