Both motorcycles feature upside-down telescopic fork front suspension and swing arm rear suspension. However, the Sportster S RH1250S 2021 has a monoshock rear shock absorber compared to the dual shock setup on the Street Rod 2017.

In terms of chassis, both models feature a steel frame. However, the Sportster S RH1250S 2021 has a tubular, load-bearing engine frame, which provides additional strength and rigidity.

The Sportster S also has a slightly steeper rake angle of 60 degrees compared to the Street Rod's 63 degrees, which may affect the handling characteristics of the two motorcycles.

Braking systems also differ between the two models. The Street Rod 2017 has double disc front brakes with a diameter of 300mm and double piston calipers.

Overall, the Harley-Davidson Sportster S RH1250S 2021 offers a more powerful and refined engine, better braking performance, and a full electronics package with advanced safety features. However, the Street Rod 2017 has its own strengths, including its iconic Harley-Davidson look, good workmanship, and a smaller turning circle. Ultimately, the choice between the two models will depend on the rider's preferences and priorities.
