Aluminium Top Box Back Rest Square: a square-profile pillion back rest for most universal aluminium motorcycle top boxes, giving firm lumbar support that helps reduce fatigue on long rides. High-density foam padding sits under a weather-resistant outer cover that handles heat, rain, dust and daily wear and holds its shape. Its contoured form gives a snug, secure fit, and it bolts on through pre-aligned mounting points with basic tools, leaving the top box unmodified. The black set has a wide main pad with a raised top tab and a smaller upper pad. Made for touring and adventure motorcycles that often carry a pillion, it boosts passenger confidence and keeps the rugged aluminium-luggage look. Includes 1 × back rest and mounting hardware.
