Used KTM 85 SX for sale
The KTM 85 SX is a 85cc two stroke kids and mini bike, which is why most of the ones for sale are outgrown rather than worn out.
5 KTM 85 SXs are listed on MWMX right now (2017 to 2025 models), asking $4,200 to $8,000, most around $6,100. Every listing shows the hours, photos and where the bike is, and you can message the seller or make an offer without an account.
A used KTM 85 SX has usually been outgrown rather than worn out, which is the best way to buy one. Check it starts easily, that the clutch (if it has one) and brakes work, that the plastics and bars are straight, and that the hours or the story match the wear on the pegs and grips. Ask for the service history (members log theirs in the MWMX Digital Garage and it shows on the listing), look at the hours against the price, and check the frame and swingarm for cracks, the fork seals for weeping and the linkage and steering head bearings for play.
