Pros and Cons in comparison

Harley-Davidson Sportster S RH1250S 2021

The Sportster S returns to the tradition of this model series - yes, it really used to be about sport! That's why the latest American creation, with its 122 hp and 125 Nm of torque, doesn't want to be a cruiser, but instead is almost classless in its pursuit of customers. What is on offer is a wonderful poser bike that is surprisingly easy to ride. The single-disc brake at the front works well and the fat 160 front tyre steers better than you would expect. Only the hard suspension makes the rider suffer on longer distances - which of course doesn't matter at all in front of the ice cream parlour. Electronics and safety are top-notch, which mitigates the tidy price for true fans.

Powerful, refined engine

brakes very good for a single-disc system

full electronics package with cornering ABS and lean angle-dependent traction control

Chassis really hard

turn-in behaviour somewhat unwilling due to wide front tyre
