BLACKBIRD Seat Foam +15 mm — Manufacturer Ref. 4508
This Blackbird seat foam increases the seat height by 15 mm compared to the original foam, allowing for a change in seat height without altering the shell. Made from high-quality closed-cell expanded polyurethane, it does not absorb water and maintains its mechanical properties over time, providing stable foam for muddy outings as well as on the road.
The 4508 foam is aimed at riders who wish to adjust their riding position and seating without modifying the seat shell. It is particularly suitable for models such as GAS GAS EC 350 F (2024), KTM 500 EXC-F SIX DAYS (2023), and GAS GAS EC 250 F (2024), depending on the original references. Installation and covering are possible with original seat covers.
