Our take on the New Genuine Harley 2021 and Up Softail Starter Motor 31400056

This is the genuine Harley-Davidson starter motor, part number 31400056, for 2021 and later Softail models. It is the factory replacement for the original starter on Milwaukee-Eight Softail cruisers, so fitment and electrical connections match the bike as built. A factory part is the safe choice when you want a direct swap without adapting mounts or wiring. Aftermarket starters can cost less but vary in build and warranty support, so riders who want the original equipment part go genuine.
