Honda Activa 125 vs Yamaha Exciter 155 VVA TCS

The Honda Activa 125 (2025) and the Yamaha Exciter 155 VVA TCS (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 Honda Activa 125 is a scooter with 124 cc, 8.3 hp and 107 kg; the Yamaha Exciter 155 VVA TCS is a cub / underbone with 155 cc, 18.2 hp and 124 kg. Power-to-weight with the rider: 45.7 hp/ton versus 91.7 hp/ton. On this measure the Yamaha Exciter 155 VVA TCS is 101% ahead.

In the simulation the Honda Activa 125 covers 0-100 km/h (speedometer) in 36.16 s and the Yamaha Exciter 155 VVA TCS in 10.46 s; the Yamaha Exciter 155 VVA TCS is quicker by 25.70 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Honda Activa 125 (ABS unknown, class assumption: no ABS) and 16.9 m for the Yamaha Exciter 155 VVA TCS (with ABS). The Yamaha Exciter 155 VVA TCS stops 1.0 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 (manufacturer claim) versus 115 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 Honda Activa 125 and class-average calibration (no accepted model-specific road test) for the Yamaha Exciter 155 VVA TCS.
