2021 Ducati Streetfighter V4 S

The 2021 Ducati Streetfighter V4 S represents Ducati's most aggressive naked bike, stripping the fairings off their flagship superbike platform to create something more streetable yet equally intense.

This is a machine that delivers superbike performance in a more upright, accessible package. The V4 engine provides relentless power delivery that rewards skilled riders with track-day capability, while the naked ergonomics make it more manageable for spirited street riding than its fully-faired sibling. The sophisticated electronics package and premium Öhlins suspension on the S variant help tame the considerable power, though this remains a motorcycle that demands respect and skill to exploit properly.

The 2021 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2020 example should focus on mileage, service history, and condition rather than spec differences.

This Ducati Streetfighter V4 S attracts experienced riders stepping up from mid-displacement nakeds or superbike owners seeking something more street-friendly without sacrificing performance. The moderate collector interest reflects its position as a current-generation flagship that bridges serious riding with everyday usability for those with the skills to handle it.
