Default Largest gas tank for a Sporty?

What is the largest gas tank I can put on a 1990 883 Custom without modifications?

Thanks!

Factory, 4.5 gallons. Do a google search for "motorcycle gas tanks". There used to be a fatbob tank out there that would fit without too many problems. It was 5 gallon.

Is it worth $500+ for another 1.2 gallons??

Look into that a little closer. I do not think the new 4.5 gallon tanks will fit onto a 1990 frame without some chopping and welding to move the brackets. There are however several versions of the fatbob tank that will fit your bike. Just be sure to have the tank sealed before putting it on your bike and using it. Look up Bikertrash on this forum and take a peek at his bike.

Google search sportster gas tank, you should find what you want then. The newer 4.5 gal. tanks do not fit without frame mods.

Damn, they raised the gas prices again? &nbsp\\;\\\\\\; No, I was talking about aftermarket tanks. Not factory ones.

Thanks!
My 2018 XL1200XS had the tiny 7.9lt tank. (1.7 UK gallons) I've recently swapped it for a 17lt (3.75 UK gallons) I've gone from filling up a 65 mile to 160 plus...

I have a 1989 sportster that came with a tank that must be at least 5 gallons. It looks ridiculous, a classic peanut tank is on my list of things to acquire for this project.

I'm not sure if it can look ridiculous. Sounds like a XL1200C which has a 4.5 gallon tank as standard. If you change to a peanut, make sure its from a 3.3 gallon bike. Mine was the 2.2 gallon version, hence with stage ll and ridden hard was only good for 60 miles max
