2023 65 SX


The 2023 KTM 65 SX benefits from the same development strategy as its bigger 2-Stroke brethren. Featuring everything the bigger motocross machines do, from a proper clutch and gearbox to the latest WP XACT. In fact, you'd be remiss to think this was anything less than a proper little READY TO RACE weapon.
