Why is my KTM 125 SX 2019 Motorcycle engine overheating?
- CChristina MendozaJul 30, 2025
Your KTM Motorcycle engine might be overheating due to several reasons. It could be due to too little coolant in the cooling system, so you should check the cooling system for leakage and the coolant level. Another cause could be too little air stream, in which case you should switch off the engine when stationary. Also, check if the radiator fins are very dirty and clean them if needed. Other potential causes include foam formation in the cooling system (drain and refill the coolant), a damaged cylinder head or cylinder head gasket (check them), or a bent radiator hose (replace it).
