The new EZ FIT Starter Motor takes the confusion out of selling starters for 1965 to 1988 Big Twins equipped with Prestolite or Hitachi starters. The starter bolts on to all three versions of the starter gear cases making this an easy installation. The starters are finished in a natural machined aluminum finish. The Compufire E-Z FIT Starter has an output of 1.6kW by using permanent magnet field design technology. Compufire P/N 53730.
