Buying Guide
Key purchase considerations help you choose the right fat-bar upgrade for your dirt bike. Focus on diameter compatibility, material strength, and bend design to match your riding style.
- Diameter and clamp compatibility: Ensure the bar’s 1-1/8″ diameter matches your triple clamps. Some bars are labeled 28mm, which equals 1-1/8″.
- Material and thickness: Aluminum options like 6061-T6 and 7075-T6 offer different strength-to-weight characteristics. Thicker walls improve impact resistance but can add weight.
- Bend shape and model fit: KTM-specific bends may improve control on those frames; universal bars suit a wider range but may require trimming or adjustment.
- Finish and corrosion resistance: Anodized finishes reduce wear and weathering from mud and water exposure.
- Installation considerations: Some bars include clamp-area scales or markings for easier alignment during installation.
- Weight vs. strength: For racing or aggressive riding, prioritize strength and stiffness over minimal weight.
