Ducati Streetfighter V4 S 2021

Ducati Streetfighter V4 S 2021

The problem of the Streetfighter V4 S with Euro4 engine, namely no power in the lower rev range but explosion in the upper rev range, has been largely rectified with the update to Euro5. Although the disgusting 208 hp are still only available at 13,000 rpm, the SF V4 S now also works acceptably at lower revs. The electronic Öhlins suspension is at its best and the brute Brembo Stylema stoppers again celebrate the penchant for the racetrack. Ergonomics and handling are also basically good, but on the racetrack you would wish for lower handlebars because of the awesome power. A perfect poser bike that also works on the country road, and on the racetrack anyway. Only the too-loud sound should be curbed a little.
