Harley-Davidson Sportster S vs Yamaha Tracer 9

The Harley-Davidson Sportster S (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 Harley-Davidson Sportster S is a cruiser with 1,252 cc, 120.7 hp and 228 kg; the Yamaha Tracer 9 is a touring bike with 890 cc, 117.3 hp and 219 kg. Power-to-weight with the rider: 398.3 hp/ton versus 399.1 hp/ton. On this measure the Yamaha Tracer 9 is 0% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the Yamaha Tracer 9 in 2.95 s; the Yamaha Tracer 9 is quicker by 0.02 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Harley-Davidson Sportster S (with ABS) and 45.0 m for the Yamaha Tracer 9 (ABS unknown, class assumption: no ABS). The Harley-Davidson Sportster S stops 0.3 m shorter. Calculated top speed: 194 km/h (manufacturer claim) 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.
