How we help

Why Motorcycle Builders Choose YiguProto

A custom build has no room for parts that almost fit. We manufacture to your design, check every critical dimension, and ship parts that bolt straight on.

Fit the First Time

We check your drawings and sample data before cutting metal. Parts that fit the first time save your whole build.

Billet Precision

Micron-level tolerances and clean machined finishes — no casting porosity, no sloppy fits.

Speed

Fast quotes and short lead times, so your bike is ready for the season, the show or the track.

Reliability

One partner for machining, molding, printing and finishing — with inspection reports on request.

Solution 01 · CNC Machining

CNC Machining for Motorcycle Parts

CNC machining is how custom motorcycle parts are made. We cut levers, pegs, engine covers and brackets from solid billet aluminum, titanium and stainless steel. The result is stronger and more precise than casting or stamping — and every part fits exactly.

Billet Levers, Pegs & Pedals

Brake levers, shift levers, foot pegs and pedals with smooth action and clean edges.

Engine Covers & Drivetrain

Clutch covers, engine cases, sprockets and push rods machined from solid stock.

Exhaust & Frame Hardware

Exhaust flanges, mounts, frame brackets and hardware built to take heat and vibration.

Solution 02 · 3D Printing

3D Printing for Motorcycle Parts

3D printing puts prototypes in your hands in days, not weeks. Test-fit a lever set to your grip. Check the look of a custom body panel. Print one-off parts and accessories for a single build — no tooling, no minimum order.

Fit & Function Prototypes

Levers, mounts, brackets and dash parts printed to your geometry for real test fitting.

Custom Bodywork & Accessories

Fairings, screens, ducts and one-off accessories with shapes machining cannot reach.

Lightweight & Electric Parts

Lightweight polymer parts for e-bike and EV conversions, where every gram counts.

Best forPrototypes, custom accessories, complex shapes and one-off builds
ProcessesFDM, SLA, SLS, MJF and SLM metal printing
MaterialsPLA and PETG for quick fit checks; nylon and carbon-fiber nylon for functional parts; TPU; aluminum
DetailsComplex geometries need no tooling — parts print straight from your CAD file
Quantities1 piece to small batches — no minimum order
TurnaroundDays — often the fastest way to test a design idea

Solution 03 · Injection Molding

Injection Molding for Motorcycle Parts

When your custom design becomes a product line, injection molding gives the lowest cost per piece. We mold grips, covers, ducting, fairing clips and small hardware in engineering plastics — with the finish and toughness production needs.

Grips, Cases & Covers

Soft-touch TPE over-molding, hard cases and protective covers that survive crashes.

Ducts, Clips & Small Parts

Air ducts, fairing clips, fasteners and dash components molded in volume.

Light & Electrical Housings

Housings, lens parts and connectors for lights and electrical accessories.

Best forGrips, covers, ducts, clips and small plastic parts in volume
ProcessesRapid tooling, production molds, over-molding, insert molding
MaterialsABS, PC, PA, PP, POM, PBT, TPU, TPE
ToolingAluminum bridge tooling for pilots; hardened steel molds for production
QuantitiesFrom pilot runs to millions of pieces
TurnaroundPrototype parts in days; production timing follows the tooling build

Solution 04 · Sheet Metal

Sheet Metal Fabrication for Motorcycles

Sheet metal builds the structure around the bike. We laser-cut, bend and weld aluminum and steel into brackets, exhaust tips, racks and custom panels — with no tooling for prototypes and fast turnaround from one unit to volume.

Frame Brackets & Mounts

Custom frame brackets, subframe mounts and shock hardware formed to your drawing.

Exhaust Tips & Heat Shields

Exhaust tips, heat shields and guards formed from stainless steel and aluminum.

Racks, Trays & Rear Frames

Luggage racks, battery trays and rear frames for custom and electric builds.

Best forBrackets, mounts, exhaust tips, racks and formed panels
ProcessesLaser cutting, CNC bending, punching, welding and assembly
MaterialsAluminum, stainless steel, steel
Surface finishPowder coating, anodizing, polishing, electroplating
QuantitiesSingle units to volume — laser-cut parts need no tooling
TurnaroundQuotes within 24 hours; prototypes typically ship in days

How we work

From File to First Ride — Five Clear Steps

You always know where your project stands. Here is the path most motorcycle part projects follow with us:

Share your files

Send 2D drawings or 3D models (STEP, STP, IGES, STL). Tell us the bike, the quantity and how the part will be used.

Free DFM review & quote

Our engineers review the design and return a quote within 24 hours, with feedback that improves fit and saves cost.

First article

We make a first sample and run dimensional checks. You approve fit and finish before the rest are made.

Pilot run

We confirm the process with a small batch. Adjustments to design, material or finish happen here — while change is still cheap.

Production & delivery

We scale up with stable quality and on-time delivery. Inspection reports travel with every batch.

Quality & Trust

Quality You Can Verify

Good parts are proven, not promised. Our quality system checks every stage, so your parts bolt straight on and stay on.

Incoming Material Control

Material certificates for every lot of billet aluminum, titanium and steel.

First Article Inspection

A full dimensional check on the first piece before the batch runs.

In-Process Checks

Operators verify critical features during the run — not only at the end.

Final Reports & NDA

Dimensional and inspection documentation with every order. Your files stay confidential.

Materials & Finishes

Built from the Right Stuff

Material and finish decide how a part handles load, heat and weather. Tell us the application, and we will suggest a grade that fits your build and budget.

Billet Metals

Aluminum 6061 and 7075, titanium and stainless steel — high strength-to-weight, machined from solid stock.

View metal materials →

Engineering Plastics

ABS, PC, PA, POM, PBT, TPU and TPE — for grips, covers, ducts and wear parts.

FAQ

Motorcycle Manufacturing — Frequently Asked Questions

We make levers, pedals and foot pegs, engine and clutch covers, sprockets, exhaust hardware, bodywork and fairing mounts, brake components, handlebars and controls, fuel system parts, brackets and racks. We build them with CNC machining, 3D printing, injection molding and sheet metal fabrication.
Send your drawings or 3D files. Most quotes come back within a few hours on business days, never more than 24 hours.
There is no strict MOQ. We make one-off parts for a single custom build, small batches for modification shops, and full production runs for product lines.
Metal parts that need precision and strength — levers, covers, brackets — fit CNC machining. Prototypes and custom one-off accessories fit 3D printing. Grips, covers and small parts in volume fit injection molding. Brackets, racks and exhaust tips fit sheet metal fabrication. Send your file and our engineers recommend the best route for free.
Billet aluminum 6061 and 7075, titanium and stainless steel for machined metal parts. ABS, PC, PA, POM, TPU and TPE for molded parts. PLA, PETG, nylon and carbon-fiber nylon for printed prototypes. We match material to load, heat and weight.
Yes. We have no minimum order, so one lever, one bracket or one intake part is a normal order for us. Prototypes and single parts typically ship in days.
Yes. Send a CAD file, a sketch with key dimensions, or the old part itself. We can reverse-engineer it, confirm dimensions with you, then machine or print the replacement.
Anodizing in many colors, powder coating, electroplating, polishing, brushing and heat treatment. We match the finish to the material and the look your build needs.
We hold micron-level tolerances on mounting and moving surfaces — the reason billet parts fit better than cast or stamped ones. Our DFM review confirms what is achievable before you commit.
We inspect incoming material, run first article and in-process checks, and provide dimensional reports with every order. All customer files and designs are confidential, and we sign NDAs on request.
