Featuring precision-engineered dual-contact seals, this bearing forms an impenetrable barrier against water ingress, grime, and corrosive contaminants. This defense preserves factory-applied lubrication and mirror-smooth raceways, ensuring buttery-smooth rotation and maintenance-free operation across mud, rain, or desert conditions.
✅ All-in-One Kit for Flawless Rebuilds
Designed as a turnkey servicing solution, this comprehensive set contains every upper and lower assembly component—pre-greased and installation-ready. Its meticulously validated fitment enables a single-session headset renewal, restoring OEM-level rotational fluidity and perfect balance with absolute component compatibility.
This restoration system embodies an unwavering dedication to steering excellence and enduring dependability. It systematically eliminates wear-induced handling degradation, creating a front-end system that reacts with telepathic precision, withstands the harshest riding environments, and delivers perpetually confident, connected, and rock-solid control at every twist of the handlebars.
