A motorcycle rear hugger is an accessory that attaches to the rear of a motorcycle to protect the rider and bike from road debris, dirt, and water splashing up from the rear wheel. It is typically made from materials like plastic or carbon fibre, and it's designed to hug the rear tire closely, protecting the bike's bodywork and rider's clothing.

Rear huggers are particularly useful for riders who frequently ride in wet or muddy conditions. They can help keep the rear suspension clean and prevent mud and water from clogging up the underside of the motorcycle. In addition, they can also help prevent damage to the rear shock absorber.

Rear huggers come in a variety of shapes and sizes to fit different motorcycle models. Some rear huggers are designed to fit the shape of the rear tire closely, while others have a more angular design. Many manufacturers also offer rear huggers in a range of colours, allowing riders to customize their motorcycle's appearance. It's a relatively inexpensive upgrade that can help extend the life of a motorcycle and keep it looking great.
