Harley-Davidson’s hard saddlebags, also known as hardbags, are typically made of durable, injection-molded ABS (Acrylonitrile Butadiene Styrene) plastic. ABS is a thermoplastic material that is known for its strength, toughness, and resistance to impact and weathering.
Harley-Davidson also offers hard saddlebags made from fiberglass and composite materials on some of their models. These materials are also known for their strength and durability, but may be more expensive than ABS plastic.
