Description
Stock seat foam deteriorates over time, leading to reduced comfort and poor ride feel—especially on longer rides where fatigue sets in fast. Factory Effex delivers OEM-spec replacement foam that restores your seat to factory performance standards, engineered to the exact hardness our factory test riders demanded. If you’re logging serious miles on your KTM, fresh foam is a straightforward upgrade that pays dividends in comfort and control.
