Micron Serpent Full Race System... a hydroformed header (meaning the pipes ain´t round, they´re thinner and wider where the pipes have sharp bends, and round only on the straight parts), combine this with an open airbox conversion kit, and DirectLink fuel map developed by Mr. Al Lighton at American Sportbike www.americansportbike.com I have this on my XB12 and get 101rwhp.
