These innovative, high-performance air filters for motorbikes are designed with cafe racers in mind. Prominent design features are their coloured, synthetic leather tops. The air filter is reusable and is easy to clean. The product follows the “Advanced Environment Friendly Engineering” philosophy of the manufacturer, meaning environmentally friendly materials are used, such as the filter of 100 per cent bio cotton. Thereby the filter contributes not only to cleaning the air but can also be partly disposed of as cotton and partly recycled.
