2018 Harley-Davidson Street Glide — Should You Buy One?
Typical asking price: $15,000–$24,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
The best-selling bagger in America, and the Milwaukee-Eight engine that arrived in 2017 fixed most of the heat and vibration complaints of the old Twin Cam. A well-maintained one is a genuinely durable touring bike. Check for heat-related wear and the quality of any modifications.
