FENRIR Motorcycle Bar-End Mirror Adapter 801-0380 — Anodized CNC Aluminium, Stainless Fasteners

The FENRIR Motorcycle Handlebar Bar End Mirror Adapter 801-0380 is a precision CNC-machined aluminum fitment that lets you securely install FENRIR brand bar-end mirrors into handlebars with existing internal threads.

This adapter is designed specifically for riders who already own FENRIR bar-end mirrors and need a reliable, direct-fit mounting solution for handlebars that have original threaded insides. Manufactured from anodized aluminum alloy with stainless steel fasteners and CNC accuracy, the 801-0380 provides solid clamping, corrosion resistance, and a clean finish that matches modern motorcycle styling.

Will this adapter fit my handlebars and FENRIR mirrors?

Yes — but only when your handlebars have original internal threading and you are using FENRIR brand bar-end mirrors. This product is not compatible with other manufacturers’ mirror systems or unthreaded bar ends. Before ordering, confirm that your handlebar ends are threaded and that your mirrors are FENRIR-branded.

• Fits handlebars with factory internal thread pattern
• Only compatible with FENRIR bar-end mirrors
• Direct bolt-on installation with included stainless screws
• Not suitable for universal or third-party mirror stems

How durable and weather-resistant is the 801-0380 adapter?

The adapter is made from high-quality aluminum alloy and finished through an anodizing process for improved surface hardness and corrosion resistance. CNC machining ensures dimensional precision so the threads and mating faces align without forcing. Stainless steel screws further prevent rusting at the fastening points.

• Anodized surface resists oxidation and abrasion
• CNC precision reduces play and vibration at the joint
• Stainless fasteners for long-term corrosion protection
• Lightweight aluminum keeps overall bar weight low

How straightforward is installation for the average rider?

Installation is intended as a direct bolt-on for compatible handlebars and requires only basic hand tools. Because the adapter matches FENRIR mirror threads and the handlebar’s internal thread, you align, insert, and torque the stainless bolts to secure the assembly. If you’re comfortable turning a wrench and verifying torque, you can fit this in minutes.

• Simple bolt-on design with no special modifications
• Requires common hand tools — socket or hex wrench
• Follow torque specs to avoid over-tightening
• Inspect fitment after first ride and periodically thereafter

What are the manufacturing highlights and quality details?

The 801-0380 is produced using CNC machining for consistent dimensions and smooth mating surfaces, then anodized to increase wear resistance and create a uniform appearance. The kit uses stainless steel screws for secure fastening and long life. These choices minimize loosening, galvanic corrosion, and cosmetic wear from road exposure.

• CNC process for tight tolerances and repeatable fit
• Anodizing provides durable finish and color stability
• Aluminum alloy body balances strength and light weight
• Stainless hardware prevents rust where it matters most

Who is this for? The FENRIR 801-0380 adapter is aimed at motorcycle owners who already use FENRIR bar-end mirrors and need a dependable, OEM-style mounting option for handlebars with internal threads. It’s ideal for riders who value precision fit, corrosion resistance, and a clean, factory look. Avoid purchasing if your mirrors are from another brand or your bars lack internal threads.
