This Frisco Sportster tank has the classic sportster shape with the custom features you want. It has a Frisco bottom low tunnel mount paired with an off-set gas cap and rear petcock bung for max fuel capacity. We also took the time to remove that unsightly flat spot on the top of all sportster tanks leaving a smooth round finish. The front of this tank is stock width while the rear has been narrowed one inch. At 2.5 gallons you’ll be looking stylish and have enough fuel to get further than just the nearest bar.
