Motorcycle Fork Left Axle Lugs

Left Axle Lug

Left axle lugs secure the front axle and, on single-rotor bikes, usually carry the brake calliper mounts. They are used on conventional forks and modern USD fork legs where separate cast axle feet clamp the axle.

Left axle lug for single-rotor brake and axle mounting

• Holds the front axle and provides brake calliper mounting on the left side for single-rotor setups
• OEM KYB & Showa mounting brackets are complex castings with adjustable internals and often hard anodized
• Available as separate inner and outer tubes, pre-assembled left inner tube assemblies or full axle lug sets
• Upgrades include performance coatings and protection to extend service life

These OEM KYB & Showa mounting brackets are complex castings, often hard anodized, with machining operations for adjustable internals, so aren't cheap. The centre sealing bolt often holds rebound adjustment - find out how to use that adjuster effectively in our clicker setup guide. We sell separate inner & outer tubes in alloy & chrome, performance coatings like Kashima Anodizing or Diamond-Like Carbon (DLC) and protective parts; see suspension mods for your budget and outer tube protectors & covers. Buy a complete left fork inner tube assembly, specific fork axle lug sets or universal holeshot clamps.
