2021 Aprilia RSV4

2021 Aprilia RSV4 sits at the top of Aprilia's sportbike range, the fully-faired V4 that everything else in the lineup gets measured against. This is a track-focused superbike that happens to be street legal, built around a compact, high-revving V4 that wants to be worked hard through the gears rather than short-shifted. Ride it the way it's designed to be ridden and it rewards precision: late, hard braking, aggressive corner entry, and a willingness to keep the engine spinning near its power peak. Ownership means accepting a firm, committed riding position and a bike that's happiest on smooth pavement or a track day rather than commuting duty. The 2021 model carried over without significant mechanical changes from the prior year, though early-production units were subject to a notable engine recall requiring full engine replacement due to components that failed to meet quality standards, so checking recall history is essential when evaluating a used example. Buyers tend to be experienced sport riders trading up from middleweight sportbikes or downsizing from track-only machines, often with some collector interest given the RSV4's standing as Aprilia's flagship. It's not a first superbike, and most shoppers know that going in.
