Ktm 125sx
The KTM 125SX and 125EXC have different motor configurations. The 125SX is designed for motocross with a more performance-oriented engine setup, while the 125EXC is built for enduro riding with characteristics suited for longer, more varied terrains. The two models may share some components, but they are not identical in terms of performance and functionality.
KTM recommends Motorex Top Speed 4T15W50 for the 125SX.
