The fine pore, silk-like to the touch, Grand Prix Cover is perfect for fine particle sand conditions. It has elastic around the bottom of the cover that allows it to sit perfectly around the air filter, preventing fine particles entering the filter and in turn your engine. The Cover will act as an additional layer of protection and extend service time between filter cleaning. 160000GP Grand Prix Cover FANTIC XE 125 21-23 XX 125 21-23 XX 250 21-23 HONDA CR85R 03-07 CR125R 00-07 CR250R 00-07 SUZUKI RM125 79-08 RM250 82-08 RM-Z 250 04-22 RM-Z 450 05-17 YAMAHA YZ 125 97-25 YZ 250 97-25 YZ125X 20-25 YZ250X 16-25
