Rear fender with side plates POLISPORT (manufacturer part number 8559500003): a replacement part that revitalizes the rear of your dirt bike. Made from injection-molded plastic using POLISPORT's proprietary processes, this set combines a rear fender and its side plates for a polished look and a glossy finish thanks to DGP (Durable Gloss Polypropylene).
The kit offers the aesthetics and durability expected in muddy and abrasive terrains: smooth finish, bright red color, and geometry that conforms to the original type. Ideal for riders who want to keep plastics close to factory standard while achieving a look identical to that used in competition.
Common compatibility: suitable for BETA RR 480/430/390 4T X-PRO models (2026). Installation as a replacement for original parts — check the mounting points and holes before installation. A practical choice for restoring the appearance and rear protection of your motorcycle while maintaining the racing spirit.
