Motorcycle Fork Leg Bare Inner Tubes

Fork Inner Tube Bare

Replacement bare fork inner tubes for conventional and Up-Side Down (USD) forks used on retro cruisers, road and offroad sport bikes. Older bikes used a chrome steel pipe sliding inside an aluminium outer case; modern USD Fork Legs reverse that arrangement. We sell complete inner tube assemblies and OEM KYB & Showa inner tubes individually — supplied empty without seals, bottoming cone or axle lug — and available in stock chrome or performance coatings such as Diamond-Like Carbon (DLC) and PVD.

Replacement inner tubes for service, repair and upgrades

• Direct replacement for damaged chromed tubes on conventional forks
• Fit USD fork legs with matching axle lug and oil lock case mounts
• Choose stock chrome finishes or performance coatings (DLC, PVD)
• Sold empty for custom rebuilds — install seals, bottoming cone or axle lug as required
• Keep tubes clean and maintained to protect finishes; use external guards when needed
