06-16 YAMAHA YZF-R6: Graves Seat Foam Pad This super durable, 9.5 mm thick textured dual-layer seat foam has a high-quality adhesive backing for easy installation. Each piece is water-jet cut in the ideal shape for a motorcycle in race trim but will also fit other models. This lightweight seat foam has been developed to provide the best balance of grip and rider maneuverability possible. The seat foam can easily be trimmed using a razor blade or shaped using a sanding pad. You can find this same seat foam on any Team Graves Yamaha R6, as well as many other race bikes in the AMA Superbike paddock.
