For a 1998 Harley-Davidson Road King, you typically need a maintenance-free 12V battery, specifically a group size of 27 or 20. The most common option is the Harley-Davidson OEM battery, which is a Yuasa YTX20HL-BS or similar. Always check your owner’s manual for specific recommendations and ensure the battery meets the required specifications for your motorcycle's electrical system.
