2021 Kawasaki KLX300 — Should You Buy One?
Typical asking price: $4,500–$6,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A middleweight dual-sport that splits the difference between a 250 and a 400 — enough power to keep up on the road, light enough to enjoy off it, and Kawasaki-reliable. A sensible, affordable choice. Valve service, drop damage, and off-road wear are the checks. Low risk.
