Narrow Frisco Sportster Gas Tank

14 reviews Write a Review

Out of Stock


For years, chopper heads have been cutting up and narrowing the classic Harley Sportster tank.  Lowering the tunnel to give it that "Frisco" style was utilized to squeeze every last drop of fuel out.  We've removed all that effort of cutting and welding and produced a great looking Frisco style narrow sporty gas tank for you.  This off the shelf gas tank includes all the good stuff, gas cap bung mounted up high, low tunnel, single piece top shell and a petcock bung set low and off to the side.


  • 1/4" NPT petcock bung
  • Universal mounting tabs
  • 2.1 gallon capacity
  • Requires cam style gas cap (not included)  - Throttle Addiction part numbers 1010 chrome, 1109 black.


  • 8" wide x 15" long x 7" tall
  • 17.5" end-of-tab to end-of-tab
  • Tunnel: 2" wide x 1.25" deep 

Tanks are pressure tested at the factory, but it is best to test again before you paint it.  Be sure fit of tank, mounting hardware, petcocks and gas caps are true prior to painting.  No stress is applied to the tabs when bolting them to the frame, this can lead to cracking of welds.  If needed, use leather or rubber washes to shim between the tabs and the backbone to ensure an even fit.  Do not sand seams or welded edges of gas tanks, if needed use a thin spread of body filler prior to painting.  Throttle Addiction warranties gas tank defects, however, we do not cover paint work.  Ensure your tank arrived damage free BEFORE you paint!

    I'm impressed with this tank.. Neat welding and it doesn't look like it will take a lot to get it ready for paint. Top marks T.A.

    It’s the best gas tank. I’d put one one dirt bike. I’d put one on a mountain bike.

    Posted by Raymond Dehn on 14th May 2014

    I really think that the product I purchased from Throttle Addiction is awesome. I am not even gonna paint it . Gonna scuff pad till it shines and powder coat it clear to show off the craftsmanship. As soon as I start my next build I will be ordering another tank.

    Great product, seems thicker sheet metal was used as compared to other tanks. The flat bottom is really nice, tank loos just right on my Shovelhead
