Pros and Cons in comparison

Triumph Street Twin 2018

Triumph Street Twin 2018

The new Triumph Street Twin cleverly continues the success story of the predecessor model; instead of radical changes, there are targeted improvements to the engine, brakes, chassis and ergonomics. The enormous 10 hp increase in power is nice, but the special character of the powerful in-line two-wheeler is still experienced more in the mid-range. Added to this is an improved look and feel at a price that is hardly higher. If you have too much money in your wallet, you can pimp and customise your Street Twin with almost 140 original accessories.

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
