Nail Motorcycle Rotors are direct bolt-on replacements for the stock Harley brake rotors. These custom motorcycle rotors are for Harley Davidson motorcycles (HD), American choppers and custom bobbers. They are full floating motorcycle rotors for maximum braking power. Inner frame is made out of billet aluminum and show-polished, outer brake disc is made of stainless steel. We now make also black brake rotors for customers that prefer the “dark” look. Nail Motorcycle Rotors are available for Harley Twin Cam models and Harley Evo models.
