Installation Notes:

• Orientation matters: Note front and rear orientation of the old foam (take a quick photo) to ensure correct alignment of the new piece.
• Assembly order: Place the foam so the contours align with the stock seat pan, then reattach the base plate if it was removed.
• Cover alignment: Refit the stock seat cover carefully, starting at the front, then work toward the rear while maintaining even tension.
• Stapling and tension: If stapling is required, use consistent spacing and avoid over-tensioning to prevent creases around edges.
• Final check: Reinstall the seat on the machine and verify there’s no rubbing against fuel lines or frame components during full-range seating and rider movement.
