KTM 125 SX Parts

Warp 9 wheels and hard parts for the KTM 125 SX, covering model years 2000 through 2025. Build a set around our 21-inch front or 17-inch supermoto front wheels, or replace what's worn: rear wheels, hubs, sprockets, brake rotors and pads, titanium axles, axle sliders, caliper brackets and wheel bearing kits.

Fitment varies across the 125 SX generations, so check the fitment list on each product before ordering. Want a wheelset built to spec? Start in the custom wheel builder, or see everything we make for KTM. Questions: (801) 699-7979.
