Triumph Street Triple S 2018

Triumph Street Triple S 2018

Clean responsiveness, great sound and a driving position - the Street Triple S offers a comfortable yet sporty riding experience. The naked bike rides with exceptional precision and agility and offers a lot of comfort, even on longer rides, where you can also enjoy the large 17.4-litre fuel tank. The electronic throttle control ensures precise response and makes it possible to set different riding modes. We also found the comparatively low vibrations for a triple and the pleasant geometry of the vehicle positive. Compared to the other bikes in the test and its two siblings, the R and RS, the chassis is a little lax - but the ingenious, husky roaring three-cylinder sound was convincing and definitely made our hearts beat faster!
