  • 19.25” long x 9” high x 7.5” wide (each tank side)
  • 3.5 gal total capacity
  • Requires 22mm petcock
  • Requires cam style HD gas caps (one vented, one non-vented)


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!
