Key Technologies
 
MARKSMAN 3D Mortise-and-Tenon Structure
Innovative 3D interlocking architecture enhances torsional rigidity and structural strength, ensuring long-term reliability and optimal performance under extreme loads.
Double Bushing System

While conventional OEM forks typically use a single bearing—insufficient for aggressive riding—RACINGBROS incorporates a Double Bushing System for improved front-end stability, increased durability, and enhanced safety in high-performance conditions.
