Sprockets for the 2024 KTM 125 SX. One sprocket on this page name the 2024 model year outright, by fitment rule or on the listing; the rest fit the 125 SX across its years. Full size KTMs run a 520 chain and a 13 or 14 tooth front. Rear sprockets fit by hub, so a rear listed for a KTM 125 to 500 of the right years fits the Husqvarna and GasGas of the same year too. The 85 runs a 428, the 65 a 420 and the 50 a 415.
Set your bike at the top of the store, with the year, and every list in it narrows to parts with confirmed fitment. Members pay the member price on every product in the store and get free standard shipping on orders over $10. Membership is $5 for the first month.
