One of our more popular rack/bag combinations for the Yamaha WR250R (and WR250X) is a Wolfman Peak Tail Bag mounted to a Pro Moto Billet Cargo Rack. This setup works great for carrying things around on the back of your WR250R Dual Sport or Yamaha WR250X Supermoto. The tail bag fits the Pro Moto Billet rack perfectly and is secured by wrapping its four mounting straps around the outer edges of the cargo rack.
For its size, the Peak tail bag holds quite a bit of stuff. The bags contents can be accessed very easily... you just un-zip the heavy duty zipper that runs around the top of the bag, then flip the top open (see photo above bottom/left). Internally, two straps keep its contents stable, and the top bungee-web is a great place to keep gloves and other things handy when off the bike. An expandable 4" gusset makes room for even more cargo when fully unzipped. The bag is stiff-sided to retain its shape and looks, whether empty or full. An optional waterproof cover is available as well.
