These 'cover-up' plates are designed to hide that very unseemly portion of the Yamaha frame where the swing arm attaches to the frame. It's like the engineers said, "hey, let's make this strong and screw the looks." Omar's ugly plates cover up the engineer's ugly mistake. They are cut from 1/8" aluminum and fit on the foot peg studs. The foot pegs hold them rattle free against the frame. They are made long and can be used with the stock side covers or cut them to use with our side paneled street tracker fender. Lightening holes are for looks only-these things are feather light. Paint 'em or polish them. They are guaranteed to turn 'ugly' into beauty.
