The BLACKBIRD +15mm seat foam incorporates racing expertise to provide a higher and firmer seating position, designed for both track and street use. Made from high-quality closed-cell expanded polyurethane, it does not absorb water and retains its properties over time — a benefit for enduro, motocross, and urban rides where the seat is put to the test.
Versatile, this foam caters to both roadsters for a more dynamic positioning and cross/enduro machines where getting on the bike and standing-to-sitting ergonomics matter. Common compatibility examples include: BETA XTRAINER 300 (2026), BETA XTRAINER 250 (2026), BETA RR 480 4T RACING (2024).
Manufacturer reference: 4B01 — A part designed for demanding riders who want to adjust their seating without sacrificing durability or moisture resistance.
