Club pannier liners. Yamaha discontinued their pannier liners, that fit FJR, sometime ago, so the club  had bespoke liners made. They are available in black only and have FJ Owners Club screen printed on the outside.
Pannier inner bags are custom designed to utilise maximum space and fit perfectly inside the pannier boxes of YAMAHA FJR1300's. Made from heavy-duty 600 x 600 Denier Polyester Vinyl Laminated PVC material and are hand stitched with strong nylon thread and premium quality zippers. Carry handles and shoulder strap to easily carry the bags into your accommodation. ABS plastic studs keep the bag dust and abrasion-free when setting them down.
Outside zip pockets for maps or other travel documents.
Price is for a pair.
