Yamaha Exciter 155 VVA TCS vs Yamaha Sirius FI

The Yamaha Exciter 155 VVA TCS (2026) and the Yamaha Sirius FI (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 Yamaha Exciter 155 VVA TCS is a cub / underbone with 155 cc, 18.2 hp and 124 kg; the Yamaha Sirius FI is a cub / underbone with 114 cc, 8.6 hp and 98 kg. Power-to-weight with the rider: 91.7 hp/ton versus 49.6 hp/ton. On this measure the Yamaha Exciter 155 VVA TCS is 85% ahead.

0-100 km/h (speedometer): Yamaha Exciter 155 VVA TCS 10.46 s, Yamaha Sirius FI 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 16.9 m for the Yamaha Exciter 155 VVA TCS (with ABS) and 18.5 m for the Yamaha Sirius FI (ABS unknown, class assumption: no ABS). The Yamaha Exciter 155 VVA TCS stops 1.7 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 88 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.
