2024 KX250 Baseline Suspension Settings And Optional ECU Map

The 2024 KX250 is suffering in these 250 MX Shootouts because of the front fork. If the KYB fork had more comfort and wasn’t so stiff, I think it would be winning or at least second. The engine package is really good with a nice amount of bottom end excitement and great mid range pulling…
