Pros and Cons in comparison

Triumph Street Twin 2019

Except for its looks, the Triumph Street Twin is not as retro as it might appear at first glance. With its water-cooled engine, riding modes, traction control and sporty chassis components, it rather gives the impression of a naked bike disguised in retro design. But all these features, in combination with the powerful torque, become its advantage, as it does not have to hide from equally powered naked bikes at the motorbike show. The Best of Both Worlds, so to speak.

powerful engine

lots of torque

potent chassis

strong brakes

cool looks

modern safety features

large range of accessories

Perhaps already too modern for the retro segment
