RAM-B-342WU Motorcycle Fork Stem Wedge Ball Base (12-32mm)

This is the full-range option, covering fork stem internal diameters from 12mm to 32mm.

FAQs

How do I know if this fits my bike? Measure the internal diameter of your fork stem bore. If it's round and falls between 12mm and 32mm, this base will fit. If the opening isn't cylindrical (for example a hex or star shape), a fork stem base won't work.

Should I buy the kit or a single size? If you're not sure of your stem size, or you swap between bikes, the RAM-B-342WU covers the whole 12-32mm range. If you know your size, the matching single-size base is the cheaper option.
