Kuryakyn footpegs are designed as a two-part splined adapter system for convenience, comfort and easy installation.
The splined adapters allow rotational adjustability for multiple angles to dial in your ideal foot placement, and can be used with any Kuryakyn footpegs or mini boards that accept splined adapters.
This convenient system allows you to change your pegs without purchasing new adapters, or switch your current pegs to a new bike by simply purchasing new adapters.
