Yamaha Exciter 155 VVA TCS vs Yuki Hammer 125

The Yamaha Exciter 155 VVA TCS (2026) and the Yuki Hammer 125 (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 Yamaha Exciter 155 VVA TCS is a cub / underbone with 155 cc, 18.2 hp and 124 kg; the Yuki Hammer 125 is a naked bike with 124 cc, 9.1 hp and unlisted weight. Power-to-weight with the rider: 91.7 hp/ton versus 47.6 hp/ton. On this measure the Yamaha Exciter 155 VVA TCS is 92% ahead.

0-100 km/h (speedometer): Yamaha Exciter 155 VVA TCS 10.46 s, Yuki Hammer 125 not reached (top simulated speed 69 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 16.9 m for the Yamaha Exciter 155 VVA TCS (with ABS) and 17.3 m for the Yuki Hammer 125 (ABS unknown, class assumption: no ABS). The Yamaha Exciter 155 VVA TCS 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: 115 km/h (estimated from power and drag) versus 83 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 both.
