BLACKBIRD RACING Seat Foam is a high-quality replacement foam made from waterproof polyurethane and designed to be perfectly interchangeable with the original seat foam. By offering increased stiffness, it helps the rider shift and balance body weight more efficiently—supporting better bike control and a more aggressive, faster riding style. With a standard height, it preserves the stock seating position while refreshing worn-out foam.
If your original foam feels soft, waterlogged, or uneven, this replacement restores a firm and consistent platform so you can move confidently on the bike and maintain better stability during braking, cornering, and acceleration.
Key features:
✅ Waterproof polyurethane foam and perfectly interchangeable with the original
