2022 KTM 125 SX

2022 KTM 125 SX sits at the entry point of KTM's full-size motocross lineup, the smallest bike a rider graduates to once they've outgrown the youth 85 SX and 65 SX machines. This is a genuine two-stroke motocrosser built for racing, not a trail bike wearing a number plate. Power comes on hard and late, rewarding riders who keep the engine spinning and aren't afraid to work a clutch aggressively through corners. It's light, flickable, and demands more rider input than a four-stroke of similar displacement, which is exactly why serious 125 racers prefer it — there's no substitute for the skill it builds.

The 2022 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2021 example should focus on mileage, service history, and condition rather than spec differences.

Owners are typically club-level or amateur racers, often teenagers or lightweight adults, moving up from the 85 SX and looking for a proper introduction to two-stroke motocross competition before stepping into larger-displacement machines. Collector interest is minimal; this is a bike bought to be raced and eventually replaced, not preserved.
