Yamaha R25 vs Yamaha Tracer 9

The Yamaha R25 (2025) and the Yamaha Tracer 9 (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 R25 is a sport bike with 250 cc, 35.4 hp and 169 kg; the Yamaha Tracer 9 is a touring bike with 890 cc, 117.3 hp and 219 kg. Power-to-weight with the rider: 145.1 hp/ton versus 399.1 hp/ton. On this measure the Yamaha Tracer 9 is 175% ahead.

In the simulation the Yamaha R25 covers 0-100 km/h (speedometer) in 6.40 s and the Yamaha Tracer 9 in 2.95 s; the Yamaha Tracer 9 is quicker by 3.45 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS) and 45.0 m for the Yamaha Tracer 9 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 5.0 m shorter. Calculated top speed: 158 km/h (GPS measurement) versus 215 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 both.
