Common questions
Does this tank come painted and ready to install?
No, this Harddrive tank is raw steel. You must complete final prep, bodywork, paint, and internal sealing before installation. Test fit it on your bike first.
Will this tank fit a Harley-Davidson other than an FXST?
Primary fitment is for FXST models. While it can be adapted for some custom applications, we strongly recommend test fitting it on your specific frame before committing to any prep work.
What type of gas cap does this tank use?
This tank features a screw-in fuel bung, designed to accept screw-type gas caps common on late-style FXST models.
