Refresh your bike’s seat feel with Blackbird Racing waterproof polyurethane seat foam, designed to interchange perfectly with the OEM foam. Increased stiffness helps you shift weight faster for improved control while keeping a standard seat height.
Upgrade your riding feel with Blackbird Racing Seat Foam (4504S), made from waterproof polyurethane foam and designed to be perfectly interchangeable with the original seat foam. If your stock foam has become soft, uneven, or waterlogged, this replacement restores a firm, consistent platform so you can move on the bike with confidence.
The greater stiffness helps you shift and balance your weight more quickly, improving bike control during acceleration, braking, and transitions—while maintaining a standard seat height for familiar ergonomics.
