Harley-Davidson Sportster S vs TVS Raider 125

The Harley-Davidson Sportster S (2025) and the TVS Raider 125 (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 TVS Raider 125 is a naked bike with 125 cc, 11.4 hp and 120 kg. Power-to-weight with the rider: 398.3 hp/ton versus 58.5 hp/ton. On this measure the Harley-Davidson Sportster S is 581% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the TVS Raider 125 in 21.08 s; the Harley-Davidson Sportster S is quicker by 18.11 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 16.1 m for the Harley-Davidson Sportster S (with ABS) and 17.3 m for the TVS Raider 125 (ABS unknown, class assumption: no ABS). The Harley-Davidson Sportster S 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: 194 km/h (manufacturer claim) versus 105 km/h (GPS measurement).

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.
