Abstract: The motorcycle seat cover is formed from a flexible sheet of heat resistant material. The sheet is shaped to custom fit the front seats, back seats or backrests of motorcycles. The sheet is provided with a seam along its free edges. An elastic cord is sewn into the free edges to form the seam or an elastic loop is enclosed within the seam to form an elastic opening for slipping the cover over a motorcycle seat or backrest. The elastic opening draws and gathers the free edges of the sheet underneath a seat or behind the backrest of a motorcycle to securely affix the cover thereto. A pair of back-to-back sheets of heat resistant material may be used to form the cover so that it becomes reversible to give the motorcycle a different aesthetic look. A vinyl sheet is placed between the sheets to make the cover reversible and waterproof.
