VOFONO 90° Motorcycle Valve Stem 11.3mm (10mm Thread) CNC Aluminium, Hard-Anodized, Locking Nut

VOFONO's 90° 11.3mm motorcycle valve stem is a CNC aluminum, hard-anodized angled valve with a locking nut designed for easier tire inflation and secure mounting on many tubeless motorcycle rims.

This angled valve replaces straight stems to give riders quicker, less awkward access to tire valves on deep or recessed motorcycle rims. Machined from 6061-T6 aluminum and finished with hard anodizing, the stem combines corrosion resistance with a bright, long-lasting appearance. Its 90° bend lets you reach the valve without removing wheels or contorting fittings, and the included locking nut helps keep the stem firmly seated against the rim.

How does the 90° angle improve tire inflation and pressure checks?

The 90° bend redirects the valve outlet toward the wheel edge, so common air chucks and pressure gauges reach the valve stem with minimal clearance issues. This saves time at roadside and in the garage while reducing the risk of damaging the stem or chuck by forcing awkward angles. It’s especially helpful on rims with deep lip designs or spoked hubs where straight stems sit tucked in.

• Easier access for standard tire gauges and compressors
• Reduces strain on valve caps and chucks
• Works without removing the wheel or tire

What materials and build features ensure durability?

VOFONO uses aerospace-grade 6061-T6 aluminum, CNC-machined for precise thread fit and consistent dimensions. The stem is hard-anodized to guard against corrosion and wear; the finish also maintains a bright visual appeal. A premium rubber seal prevents air leaks, and the supplied locking nut secures the stem against vibration and movement.

• 6061-T6 CNC aluminum body for strength and light weight
• Hard-anodized surface resists oxidation and abrasion
• Premium rubber seal and locking nut to prevent leaks and loosening

Which motorcycles and rims are compatible with this stem?

This valve is designed around an 11.3 mm hole diameter and a 10 mm mounting thread, matching many Japanese OEM and aftermarket tubeless motorcycle rims. It fits a wide range of motorcycles — from Honda, Yamaha, Kawasaki, and Suzuki to many Harley-Davidson, BMW, and Triumph models that accept 11.3 mm valve stems. Always verify your rim’s valve hole and thread size before purchase.

• Mounting thread diameter: 10 mm (0.39 in)
• Required rim hole diameter: 11.3 mm (0.44 in)
• Common fit for many tubeless motorcycle rims and OEM replacements

How simple is installation and routine use?

Installation is straightforward: push the stem through the rim valve hole, seat the rubber gasket, then tighten the included locking nut to hold the stem in place. No tire dismount is usually needed if your rim hole and thread match; check fitment first. For routine use, the angled outlet lets you attach an air hose or gauge quickly, and the durable finish reduces corrosion worries over time.

• Push-in fit with rubber seal; lock with included nut
• Usually no tire removal required for standard tubeless rims
• Fits common motorcycle air fittings and caps

Who is this for: Riders and mechanics who want faster, safer tire inflation on motorcycles with recessed or deep-set valve locations. This stem is ideal for owners of Japanese OEM wheels and many cruisers or sport bikes that accept 11.3 mm valve stems. Choose VOFONO’s CNC aluminum angled stem when you need a corrosion-resistant, secure replacement that makes pressure checks and inflation easier without modifying wheels.
