Water pump cover protection Beta RR 4S '20 onwards from Polisport. Robust protection made from PA6 (Polyamide) for efficient wear, impact and high temperature, but at the same time very light (about 100 g). Easy and intuitive mounting, it is not necessary to disassemble the water pump cover. Thanks to the sealing ring and the perfect fit of the cover to the original generator cover, its appearance and original coloring are preserved.
