The 2021 Benelli Imperiale 400

2021 Benelli Imperiale 400 sits at the entry point of Benelli's roadster range, aimed squarely at riders who want classic British-standard looks without the classic British electrics and oil leaks. This is a low-revving, single-cylinder machine built for relaxed street riding rather than highway blasting or canyon carving. The upright seating position, low seat height, and modest power delivery make it an easy, unintimidating bike to live with, whether that's a daily commute or a weekend ride to nowhere in particular. It rewards a calm right hand more than an aggressive one, and that's the point. 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. Typical buyers are newer riders or returning riders downsizing from something bigger and more expensive to maintain, drawn to the retro styling without wanting the fragility of a vintage machine. It also appeals to city riders who want personality at a low price point, not speed or investment potential. Collector interest remains low, so this is a bike bought to be ridden and enjoyed, not stored away.
