I have a 08 - 17 Hayabusa Roaring Toyz swing arm that is 6 inch over stock , it's complete ready to install, The rear brake bracket uses a right front caliper thats also included, the arm has a nitrous bottle bracket . When Roaring Toys first made a order of swing arms for the 2008 Hayabusa they had the owner of Myrtle West make them there is a logo on the bracket. Arm has serial number to verify the model and size of arm. Arm is used. Pictures will be up soon, pm me if you have any questions thank you.
