2021 Aprilia RS 660 — Should You Buy One?

Typical asking price: $8,500–$11,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A modern, light, twin-cylinder sportbike that's genuinely brilliant to ride and refreshingly usable. The tradeoff is Aprilia's thinner US dealer network and pricier parts. Newer, so long-term reliability is less proven; verify software updates, dealer access, and any crash history.

What we checked
