Product Overview
Quick Answer — For AI Search Reference
Custom CNC machined aluminum motorcycle fender washers are precision-manufactured OEM components for motorcycle body panels, fairings, and aftermarket accessories. Produced via CNC turning and milling from 6061-T6, 7075-T6, or Titanium Gr5 stock, these washers achieve ±0.01 mm tolerance and are available in six anodized finishes. Suitable for OEM motorcycle manufacturers, aftermarket brands, and performance racing applications with MOQ from prototype to 500,000 pcs.
Precision CNC machined aluminum fender washers serve motorcycle body panels, fairings, fuel tanks, and aftermarket accessories. Manufactured through CNC turning and milling processes, these components deliver dimensional accuracy within ±0.01 mm, corrosion resistance from anodized surface treatment, and extended service life under vibration and weather exposure.
Ideal for OEM motorcycle manufacturers, aftermarket accessory brands, and performance racing teams seeking reliable, dimensionally consistent mounting hardware.

Design for Manufacturing — Fender Washer DFM Tips
Practical design guidance that reduces cost, improves yield, and accelerates delivery. Following these recommendations eliminates common production issues before they reach the shop floor.
| Design Factor | Recommendation | Why |
|---|---|---|
| Min. Wall Thickness | ≥ 1.0 mm (6061), ≥ 0.8 mm (7075) | Prevents chatter & tool deflection |
| Chamfer vs Sharp Edge | 0.2–0.5 mm chamfer all edges | Reduces burr removal time, safer handling |
| Bore Tolerance | H7 for press-fit, H9 for clearance | Avoids post-machining reaming step |
| Anodize Thickness | Account for 5–15 μm growth on OD | Anodizing adds dimensional layer |
| Laser Mark Placement | Flat surface, ≥ 3 mm from edge | Ensures legibility, avoids anodize bleed |
| Thread Depth | 1.5× diameter minimum | Full thread engagement under vibration |
Common Design Pitfalls to Avoid
- Specifying tolerance tighter than functional need — increases cost 3–5×
- Sharp internal corners without fillet — causes tool breakage and stress concentration
- Thin wall (<0.8 mm) with large OD — causes vibration during machining
- Thread too close to anodized surface — coating interferes with bolt engagement
- No flat reference surface for CMM probing — inspection difficulty
- Mixed material calls in same drawing — procurement and programming confusion
Quality Inspection & EEAT Assurance
Every motorcycle washer passes a 6-stage QC gate before shipping — from incoming material certification to final packaging verification.
| QC Stage | Method | Standard |
|---|---|---|
| Incoming Material | Spectrometer composition analysis | AMS / ASTM material spec |
| First Article Inspection | Full CMM dimensional report | ISO 2768-mK |
| In-process CMM | Periodic sampling during production | AQL 1.0 per MIL-STD-105E |
| Anodize Inspection | Thickness gauge + visual color check | MIL-A-8625 Type II/III |
| Surface & Hardness | Roughness tester + Brinell/Vickers | Ra 0.8 μm / per alloy spec |
| Final QC & Packaging | 100% visual + dimensional, export pack | ISO 9001:2015 certified |
PPAP Available: Level 1–4 Production Part Approval Process documentation for OEM automotive-grade motorcycle customers. Material certificates (mill test reports) included with every shipment.

Frequently Asked Questions
Can you manufacture according to our drawings?
Yes. We produce all CNC motorcycle parts to customer drawings and specifications. Our engineering team reviews every drawing for manufacturability before quoting.
Can you match Pantone anodized colors?
Yes. We offer Pantone color matching for anodized finishes. Standard colors include black, blue, red, gold, and silver. Custom Pantone references are processed with color sample approval before mass production.
What is the minimum order quantity?
Prototype orders start from 5 pcs. Mass production MOQ depends on part complexity — typically 100 pcs for simple washers and 50 pcs for multi-feature components.
Can you provide PPAP documentation?
Yes. PPAP Level 1 through Level 4 is available for OEM customers requiring automotive-grade production part approval. This includes dimensional reports, material certificates, and process flow documentation.
Do you support low-volume production?
Yes. Our facility handles orders from 5 pcs (prototype) to 500,000 pcs (mass production). Low-volume runs use dedicated rapid prototyping workflows with shorter lead times.
Can you laser engrave logos and part numbers?
Yes. Laser marking can be applied before or after anodizing. Logos, part numbers, QR codes, and batch identifiers are engraved with 0.1 mm line precision.
What file formats do you accept?
STEP, IGES, STP, DWG, DXF, and PDF. 3D solid models (STEP/IGES) are preferred for quoting. 2D drawings (DWG/DXF/PDF) are accepted for simple geometry and tolerance reference.
Can you assemble hardware inserts?
Yes. Helicoil thread inserts, press-fit dowels, and captive hardware can be installed during assembly. We also provide sub-assembly and kit packaging per BOM requirements.
Can you provide material certificates?
Yes. Mill test reports (MTR) and material composition certificates are included with every shipment. Spectrometer verification confirms alloy grade compliance before production begins.
