BLACKBIRD standard seat foam (ref. 4501S) – Designed for the Cross universe, this Blackbird seat foam replicates the dimensions and profile of the original seats for a simple and reliable replacement. Made from high-quality closed-cell expanded polyurethane, it does not absorb water and maintains its mechanical characteristics over time, providing consistent seating during long off-road days.
The foam offers a firm seating surface that promotes stability on the seat during both standing and sitting riding phases, while limiting water penetration into the structure. Easy to install as a replacement for the original foam: it fits the manufacturer's mounts and dimensions for a reassembly without modification. Ideal for restoring the seat of a motocross bike or preparing a seat before a reconnaissance, compatible with several EXC Racing models (e.g., KTM 520/400 EXC Racing from 2002).
