The big kids don’t get to have all the fun, and that’s why the 2023 KTM 50 SX Factory Edition exists. The Factory Edition of the micro-racer takes the standard 50 SX and adds an impressive collection of upgrades for a bidding Supercross World Champion. Although only the graphics are new this year, it’s worth reviewing how the Factory Edition earns that lofty moniker.
- The new Factory Edition has an FMF expansion chamber and silencer for additional power. The jetting is altered to match the changed flow characteristics.
- With the additional power production, KTM installs a smaller rear sprocket, raising the gearing for a higher top speed.
- The automatic clutch has a different engagement rate to match the change in gearing and power.
- The ignition and clutch covers are CNC-machined aluminum.
- Factory Edition KTMs always get more orange. In the case of the 2023 model, that means an orange gripper seat and orange inserts in the chain guide. The ODI grips are a contrasting gray.
- The tires are upgraded to Dunlop Geomax MX53 rubber.
- The 2023 KTM 50 SX Factory Edition will set you back $5599. That’s a $900 bump up from the standard model.
