Harley-Davidson Heritage Classic vs Kuba Terra125
ESTIMATED SIMULATION
Run the comparison →The Harley-Davidson Heritage Classic (2025) and the Kuba Terra125 (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 Harley-Davidson Heritage Classic is a cruiser with 1,923 cc, 91.2 hp and 326 kg; the Kuba Terra125 is a naked bike with 125 cc, 9.5 hp and unlisted weight. Power-to-weight with the rider: 227.4 hp/ton versus 48.7 hp/ton. On this measure the Harley-Davidson Heritage Classic is 367% ahead.
0-100 km/h (speedometer): Harley-Davidson Heritage Classic 3.78 s, Kuba Terra125 not reached (top simulated speed 89 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.7 m for the Harley-Davidson Heritage Classic (ABS unknown, class assumption: no ABS) and 17.3 m for the Kuba Terra125 (ABS unknown, class assumption: no ABS). The Kuba Terra125 stops 0.4 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 194 km/h (estimated from power and drag) versus 89 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 both. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.

Data sources and calibration
Specifications: the sources below (manufacturer pages, plus road-test or spec sites where the manufacturer gives no figure). Acceleration, braking and top speed: Moto Kıyas physics simulation (power/torque curve, gearing, drag, traction and wheelie limits, ABS assumption), calibrated against published road tests where available. Estimated, not measured.
