Kahuna
Origin
The Kahuna has been Kona's flagship hardtail for two decades, evolving from a steel cross-country race bike into a versatile 29er trail hardtail. The name and spirit — inspired by Hawaiian surf culture — has remained constant even as the platform embraced bigger wheels, dropper posts, and Boost spacing. It sits above the more entry-level Mahuna, offering a RockShox air fork, 12-speed drivetrain, and progressive geometry for riders ready to push on local singletrack.
