Riser Adapter Insert Set for Harley Springer Front Ends 3/4-16 to 1/2-13

This riser adapter insert set is designed for Harley-Davidson and aftermarket Springer front ends.

The inserts thread into the rear legs of the Springer fork and provide a threaded mounting point for standard risers. The outer threads are 3/4-16 UNF, while the internal threads are 1/2-13 UNC, allowing the use of common 1/2-13 threaded handlebar risers.

Designed for use on stock or replica Springer front ends with 1 inch outer diameter rear legs, these inserts require tapping the fork legs prior to installation. This setup is commonly used when adapting aftermarket risers to traditional Springer front end assemblies.

At Boomers Bike Shop, we stock mounting hardware that fits correctly and supports proper handlebar alignment on real-world builds.
