The BLACKBIRD standard seat foam (ref. 4900S) is designed for motocross and enduro riders seeking a reliable, durable seat that matches original specifications. Made from closed-cell expanded polyurethane, this foam does not absorb water and retains its mechanical properties over time. Developed with the help of championship teams, it replicates the shape and height of the original seat for easy installation without modifications.
Ideal for both track and training, this foam provides a stable seating position to maintain control during position changes and weight shifts on the seat. It easily mounts as a direct replacement and is suitable for motocross bikes of the same shell generation. Examples of compatible models: GAS GAS EC 500 F (2025), GAS GAS MC 450 F (2025), GAS GAS EC 450 F (2025).
