Ktm Sx 250 Review

Used Buyer Review

The KTM 250 SX is a proper weapon — KTM's two-stroke motocross flagship hasn't changed its aggressive personality across generations. That's exactly the problem and the appeal. Buy a neglected one and you're inheriting someone else's mechanical disaster; buy a well-kept example and you've got one of the sharpest 250s ever bolted together. The WP suspension is genuinely excellent when serviced, and that Kokusan-ignitioned motor rips with an urgency that'll embarrass plenty of 450s through the mid-range. It's addictive. Here's the honest part: two-strokes demand maintenance discipline. Check the powervalve — they gum up and owners ignore them. Pull the pipe and inspect the piston before handing over cash. Top-end rebuilds are cheap if you do them yourself, expensive if you've been neglecting intervals. Anything post-2019 benefits from the revised frame geometry, which calmed the notoriously twitchy handling without killing the fun. Under $4,000 you're gambling; spend a bit more for a documented, recent-season bike.
