Harley-Davidson Nightster Special vs Honda XL750 Transalp

The Harley-Davidson Nightster Special (2025) and the Honda XL750 Transalp (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 Nightster Special is a cruiser with 975 cc, 88.5 hp and 225 kg; the Honda XL750 Transalp is a adventure bike with 755 cc, 90.5 hp and 210 kg. Power-to-weight with the rider: 295.0 hp/ton versus 317.6 hp/ton. On this measure the Honda XL750 Transalp is 8% ahead.

In the simulation the Harley-Davidson Nightster Special covers 0-100 km/h (speedometer) in 3.17 s and the Honda XL750 Transalp in 3.23 s; the Harley-Davidson Nightster Special is quicker by 0.06 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 49.1 m for the Harley-Davidson Nightster Special (ABS unknown, class assumption: no ABS) and 41.4 m for the Honda XL750 Transalp (with ABS). The Honda XL750 Transalp stops 7.7 m shorter. Calculated top speed: 180 km/h (estimated from power and drag) versus 196 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.
