I just bought a brand new 2018 YZ450FX.

IMS only makes an FX in 2.4 tank that fits into the frame and a 2.9 that has the big shrouds that fill with fuel.

Dirt Rider has the fix. Few easy steps to fit the 450F 2.9 tank into the FX by supposedly moving battery and not much else. Anyone in here do this mod and can help me out? I am finding out it is not nearly as easy as they led me to believe! Any tips would be great if you have done this! Thanks!

I would like to see a link to that article. Not sure where they relocated the battery to in order to fit the 450f tank?

Also, I have the 2.5 gal IMS tank for my 2016 450fx and it holds more than 2.5gal, more like 2.7 gal. But that isn't guaranteed for every tank that gets produced.
