Yamaha MT-07 vs Yamaha Sirius FI

The Yamaha MT-07 (2025) 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 MT-07 is a naked bike with 689 cc, 72.4 hp and 183 kg; the Yamaha Sirius FI is a cub / underbone with 114 cc, 8.6 hp and 98 kg. Power-to-weight with the rider: 280.7 hp/ton versus 49.6 hp/ton. On this measure the Yamaha MT-07 is 466% ahead.

0-100 km/h (speedometer): Yamaha MT-07 3.48 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 17.3 m for the Yamaha MT-07 (ABS unknown, class assumption: no ABS) and 18.5 m for the Yamaha Sirius FI (ABS unknown, class assumption: no ABS). The Yamaha MT-07 stops 1.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 195 km/h (GPS measurement) 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 model-specific parameters calibrated against published road tests for the Yamaha MT-07 and class-average calibration (no accepted model-specific road test) for the Yamaha Sirius FI.
