Forged Aluminum Alloy Motorcycle Main Frame Side Beam

Strengthen the very core of your motorcycle with this hot-forged aluminum alloy main frame side beam. Engineered as a structural foundation for custom chassis builds and high-performance restorations, this component delivers race-bred rigidity and mass reduction where it matters most.

Premium Forged Construction: Hot-forged from high-strength aluminum alloy, optimizing grain flow along critical load paths for exceptional fatigue resistance and structural integrity—without the weight penalty of steel.
Precision-Machined Interface Surfaces: Fully CNC-machined to exacting tolerances at all mounting points, ensuring seamless integration with your main frame, engine cradle, and suspension components.
Optimized Strength-to-Weight Ratio: Forged aluminum architecture provides maximum stiffness per gram, reducing unsprung and overall chassis mass while maintaining the torsional rigidity required for precise handling.
Customizable Finish Options: Available in a range of professional-grade surface treatments—including bead blasting, hard anodizing, or powder coating—allowing the beam to either blend invisibly or stand out as a deliberate design element.

Applications:

• Custom Frame Construction: Essential for builders fabricating one-off street trackers, café racers, or performance specials requiring a lightweight yet unyielding structural backbone.

• Chassis Reinforcement: Ideal as a direct replacement or reinforcement for OEM side beams on vintage or modern platforms, restoring rigidity and sharpening handling response.

More than just a structural rail, this main frame side beam is the forged sinew of your motorcycle’s chassis—delivering precision, durability, and weight savings in a single, machined component. Whether you’re laying out a new frame or resurrecting a classic, it’s the backbone your build deserves.
