At Moto-House MX, we are the go-to destination for performance parts, kits, and accessories for the KTM 250 SX. With over 40 years of experience building and tuning off-road bikes, our team helps you get more out of your KTM 250 SX.
The KTM 250 SX is a 2-stroke bike known for its explosive hard-hitting powerband, lightweight agility, and race-winning throttle response on the track. With the right upgrades you can unlock its potential. We focus on top-end and cylinder work, exhaust systems, reed valves, and clutch upgrades. Whether you are doing a full top-end rebuild, adding power, upgrading control, or protecting vital components, we carry the parts to do it.
Rebuild or build up the engine with Vertex, Wiseco, ProX, Cylinder Works, Athena, VHM, and Hot Rods pistons, cylinders, gaskets, and crank components. Add sharp throttle response with V-Force (Moto Tassinari) and Boyesen reed valves. Put the power to the ground with Rekluse and Hinson Racing clutch components, FMF and Pro Circuit exhaust systems, and Twin Air, Pro Filter, No Toil, and UNI air filtration. Improve control and drive with Renthal, ProTaper, ODI, ARC, Raptor Titanium, Flo Motorsports, Works Connection, RFX, and Xtrig bars, sprockets, levers, footpegs, and controls, plus D.I.D. Racing Chain and RK Chains. Protect the bike with Acerbis, UFO, Polisport, Cycra, and Works Connection plastics and guards, stop harder with EBC, Galfer, Moto-Master, and SBS brakes, keep it turning with Pivot Works, All Balls, SKF, and Race Tech bearings and suspension components, keep the system powered with Fire Power, GET Battery, NGK, and Trail Tech electricals, and maintain it with Maxima, Motorex, Muc-Off, and Motul chemicals. Moose Racing, Moose Offroad, 100%, and Alpinestars round it out with everything from hardware and protection to rider gear.
