The 1986 Benelli 900 Sei Sport
1986 Benelli 900 Sei Sport sits near the top of Benelli's road lineup as the brand's flagship sport tourer, built around a six-cylinder engine layout that was unusual for anything outside Italian exotica at the time. In practice, that straight-six delivers a smoothness you don't get from the parallel twins and triples dominating the class, with a broad spread of power that pulls cleanly rather than demanding you chase the redline. It's a bike built for covering distance at a steady clip, not for hammering apexes, and the extra weight over the front end makes itself known the moment you tip into a tight corner. Owners describe it as more of a relaxed grand tourer with a distinctive engine note than an outright sport machine. The 1986 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1985 example should focus on mileage, service history, and condition rather than spec differences. Today it draws riders who already own more common Japanese or German machines and want something mechanically unusual, along with collectors drawn to the six-cylinder layout and Benelli's standing as a small, idiosyncratic manufacturer.
