Cnc Machined Motorcycle Parts from BQUQ are precision components—triple clamps, brake levers, foot pegs, sprocket hubs, and custom engine covers—cut from billet aluminum or steel on 5-axis CNC centers. You get ±0.005 mm dimensional tolerance, 0.01 mm true position runout on bearing surfaces, and surface finish down to Ra 0.4 µm, all shipped within 15 days from our Dongguan factory. We have run this 20-year-old facility with 40+ CNC machines, and we do not hide behind minimum order quantities—send one piece, we machine it.
How We Hold 0.01 mm Runout on Triple Clamps and Sprocket Hubs
Runout kills motorcycle handling. If your steering stem bore is off by 0.05 mm, you feel a wobble at 120 km/h. We eliminate that with a two-step process: rough machining leaves 0.5 mm stock, then we stress-relieve the part at 180°C for 2 hours to release internal material stress. The finish pass runs at 8,000 RPM with a 0.15 mm depth of cut, using a hydraulic expansion chuck that grips the tool with 3 µm concentricity. Every triple clamp and sprocket hub is checked on a CMM with a 0.5 µm resolution probe. For your reference, our CNC machining tolerances guide explains how we achieve this without inflating your cost.
Materials and Heat Treatment We Use for Crash-Ready Parts
We machine parts that hit the pavement. For brake levers and foot pegs, we use 7075-T6 aluminum—yield strength 503 MPa, hardness 150 HB. For sprockets and shift shafts, we switch to 4140 chromoly steel, hardened to 48 HRC via oil quenching and tempering at 400°C. If you need stainless, we run 17-4 PH at H900 condition (40 HRC). We do not use recycled billet; every bar comes with a mill certificate traceable to the heat lot. For titanium parts (Ti-6Al-4V Grade 5), we quote on request—it machines slower, but we hold the same ±0.005 mm tolerance.
Surface Finish That Slips Through Dust and Rain
Raw machined aluminum corrodes. We offer three standard finishes: clear anodize (8-12 µm thickness, 500-hour salt spray test), hard anodize (40-60 µm, 68 HRC equivalent surface), and black oxide for steel parts. For visible parts like fork caps and bar clamps, we run a 600-grit bead blast before anodizing—this hides fingerprints and gives a matte, non-glare look. Surface roughness is speced at Ra 0.8 µm on sealing surfaces and Ra 0.4 µm on bearing journals. If you need a polished mirror finish, we add a 2-day buffing step.
Inspection Before Every Shipment—Not Just a Random Sample
We inspect 100% of Cnc Machined Motorcycle Parts before they leave our floor. That is not a marketing claim; it is our work instruction. Each part goes through a 12-point check: critical dimensions on a CMM, runout on a V-block with a dial indicator, hardness on a Rockwell tester, and thread gauges for every tapped hole. We photograph the first article and email it to you with the inspection report. If any dimension is out of spec, we scrap the part—we do not rework structural components. Our CNC cutting tool selection guide covers how tool geometry affects surface integrity, which is why we change inserts every 200 parts.

Why a 20-Year Dongguan Factory Beats a Job Shop Down the Street
We are a Cnc Machined Motorcycle Parts maker in Dongguan, China—not a broker. Our factory floor has 40 CNC lathes and machining centers, including 5-axis DMG MORI units. That vertical integration means we do not mark up a subcontractor’s work. We also do stamping and springs in-house, so if your assembly needs a bracket and a return spring, we ship them together. Precision manufacturing is our only business; we are not a general machine shop taking any job that walks in. This specialization is why our scrap rate is 0.8% and our on-time delivery is 97.4% over the last 12 months.
Pricing and Lead Time for Prototype vs. Production Runs
Prototype (1–5 pieces) takes 7 days and costs 40% more per unit than production. Production (50+ pieces) drops unit price by up to 55% because we can use multi-part fixtures and run lights-out machining overnight. We quote both options on the same drawing—you decide after seeing the numbers. If you need a rush prototype for a race weekend, we offer a 72-hour express service at 1.5× standard rate. No MOQ applies to either path. For a deeper look at how we estimate costs, our article on sustainable precision manufacturing explains why energy-efficient machining keeps your unit price stable even on small batches.
Custom Threads, Bore Sizes, and Engraving—Without Extra Tooling Fees
Your OEM part might use a weird thread pitch like M8×0.75, or a 12.7 mm bore that is not metric or imperial. That is normal for motorcycles. We stock a library of 1,200+ thread taps and 300+ reamers, so we rarely charge tooling fees. If we need a custom form tool, we charge a one-time $80–150 fee, and you keep the tool after the order. Engraving (logo, part number, torque spec) is free for the first 10 characters—we do it with a 0.1 mm depth end mill, not a laser, so it survives anodizing.
Packaging and Documentation for Global Shipping
We ship Cnc Machined Motorcycle Parts in individual foam-lined boxes, wrapped in VCI paper to prevent corrosion during ocean freight. Each box carries a label with your part number and our inspection stamp. You get a packing list, a material certificate, and a dimensional report in PDF format. We ship via DHL, FedEx, or UPS for air freight (3–5 days), or by sea freight (25–30 days) for bulk orders. Customs clearance is handled by our forwarder; you only pay for the freight. Our made in China parts meet ISO 9001:2015 and IATF 16949 quality systems, which most US and EU importers accept without additional audits.
What is the minimum order quantity for custom motorcycle parts?
No MOQ—we machine one piece for prototyping and 10,000 pieces for production at the same quality level.
Can you machine a part from a sample I send by courier?
Yes, we can reverse-engineer a physical sample using our CMM and CAD software, and we provide the step file for your approval before machining.
How do you ensure quality on low-volume orders?
Every part, regardless of order size, goes through the same 100% inspection protocol—we do not skip checks for a single-piece order.
What is the fastest lead time for a custom brake lever prototype?
72 hours if you approve the drawing before 10 AM Beijing time, plus shipping time; standard prototype lead time is 7 days.
Send us your drawing in STEP, IGES, or PDF format. We reply with a firm quote within 12 hours—no vague ranges, no hidden tooling fees. Email sc@bquq.com or WhatsApp +86 13713157787. If you have a part in hand, photograph it and send that; we will measure it and quote the CNC machined version.
