Braille lists the B3121 as a lightweight AGM race battery; the 1998-present baggers and dressers fitment comes from our listing. Confirm polarity and tray size on your bike before ordering.
Keep it charged with a lithium-compatible maintainer, and see all motorcycle batteries or the parts and accessories we carry.
