its the replacement viper cover to the original.. basically if you do not have the original launch cover that says sxviper and has the cool design, but you still need a direct model form fit cover, this is it. Its exact fit for the viper but just a generic yamaha logo on it. if you want an original with the SXviper on it, good luck if there are any in decent shape your giving 300 for them even if they have holes and such.. if they are original and mint 375 to 400. They are rare.. Hence the need for a factory fit replacement. SMA-COVER-47-00 for blue or SMA-COVER-47-01 for red.. I have the red one on order and should be delivered soon... I have 2 red vipers one with original factory cover with the sxviper on it the other sled did not come with one but this will be cool enough. hell I had to sew up a 6 inch hole in the original one and its faded but still looks nice just needs some love. I wish yamaha would put out a revised version of the 2 stroke. Like modern supped up factory internals, 160 hp stock triple. Something from there skunk works..lol
