A fuel cap sits on top of the tank like a crown on a queen's head. Have you ever seen an uninspiring, plain and ordinary crown of the queen? We didn't think so. That is why we think Harley-Davidson motorcycles need to be honored with a Performance Machine custom crown for their fuel tanks. Throw away that OEM piece of cap, and screw-in a premium PM cool cap for a highend look of royalty, without the high-end price. CNC'd from aircraft grade aluminum, our unique vented fuel caps are an instant custom addition to 1996-up H-Ds and compliments our current cover line of accessory designs. The PM proprietary LED Fuel Gauge is user programmable for multiple applications and features bright LED lights that energize when full and shut off as fuel level drops.
