J's Racing normally makes speed parts only for Hondas but in this case their GT Wing Cover would make a useful addition to protect the GTC-200 from the weather elements (UV from the sun, dust and of course rain). The cover is made from polyester with 3 layers of coating on the surface for waterproofing. A fleece like material is attached on the inner side of the cover to balance the durability and air permeability. The cover fits most wings up to 1600mm wide so is perfect for the GTC-200.
I bought my cover from RHD Japan. Cost including shipping came up to 10,143 Japanese Yen. Picture below of the cover in its packaging. Part number is DGW-C2.
