We machine IVC customer motorcycle parts from your 3D model and 2D drawing: triple clamps, fork caps, linkage plates, engine covers. 5-axis milling and turning in aluminium and stainless steel, held to ±0.005 mm, with 100% inspection before shipment.
Most of these show up after the parts arrive, not on the drawing.
A 0.05 mm error on a fork cap thread means the cap bottoms out before the O-ring seals. Oil weeps past the threads, damping changes, and the rider feels it in the first lap. We hold thread fits to ±0.005 mm and check pitch diameter with thread gauges before the parts leave the floor.
If the fork bore and the steerer bore are not coaxial, the clamp pinches the fork tube on one side. The fork binds, and stiction rises. We bore both features in one setup on a 5-axis center so the center distance stays true from the first part to the last.
A linkage plate as-machined from 6061-T6 can look fine on the bench and still flex on the track. We check wall thickness against your load direction and suggest 7075-T6 or a ribbed section when the plate is asked to carry more than the drawing implies.
Sharp internal corners at bolt bosses concentrate stress. A small fillet and a change in the spot-face depth often removes the failure. Our free DFM analysis flags these before cutting metal, so you are not paying for a second run.
Two capabilities do most of the work on IVC customer motorcycle parts.
Triple clamps, fork lugs, and linkage plates carry bores and faces on several planes. If each face is cut in its own setup, each setup adds its own error. We run these parts on 16 simultaneous 5-axis machining centers, so the fork bore, steerer bore, and caliper mounts come off the same zero.
Our rotary table is Ø400 mm, and the largest travel is 4,000 × 400 × 150 mm. That covers a full triple clamp, a swingarm section, or a set of matching brackets in one batch. Small runs are fine: no minimum order quantity, from one prototype to 10,000+ parts.
Axle spacers, fork caps, and shock-eye bushings are turned parts until they are not. A cross hole, a flat, or a slot usually means a second operation on a mill, and that is where runout creeps in. Our 16 mill-turn centers cut the OD, the thread, and the cross features in one cycle.
Thread fits on fork caps and axle nuts are checked with go/no-go gauges. Surface finish lands at Ra 0.8–1.6 μm on sealing diameters, and we can push to Ra 0.2–0.8 μm when a fork tube or a shock shaft needs it.
| Part | Material | Finish |
|---|---|---|
| Triple clamp | 7075-T6 or 6061-T6 | Hardcoat anodize, black |
| Fork cap | 6061-T6 | Clear anodize |
| Linkage plate | 7075-T6 | Bead blast, clear anodize |
| Engine cover | 6061-T6 | Powder coat or anodize |
| Axle spacer | 304 or 316 stainless | As machined or tumble |
| Shock eye bushing | Bronze C93200 | As machined |
| Exhaust bracket | 304 stainless | Brushed |
| Master cylinder cap | 6061-T6 | Hardcoat anodize |
You can place the whole job, prototype through production, with one supplier.
Complex parts with bores and faces on multiple planes, cut in one setup to ±0.005 mm.
Prismatic brackets, plates, and covers where a single index is enough and cost matters.
Round parts with cross features finished in one cycle on mill-turn centers.
Fit checks and track tests before you commit to a production run.
Anodize, plating, powder coat, bead blast, and laser marking.
Brackets, guards, and housings when machining from billet is not the right call.

These are the figures that decide whether a run goes smoothly.
Fifteen years of production work, with 3 wholly-owned plants and 7,600 m² of manufacturing space in Dongguan and Singapore.
16 simultaneous 5-axis centers, 12 four-axis mills, 27 three-axis machines, and 16 mill-turn centers under one roof.
Bores, threads, and sealing diameters checked with gauges and CMM reports on request.
Raw material check, in-process monitoring, and final inspection on every order.
Send a 3D model and 2D drawing, and we return a cost estimate and lead time.
Travel up to 4,000 × 400 × 150 mm, plus a Ø400 mm rotary table for indexed work.
Triple clamps and linkage plates need concentric bores and stable wall sections. We cut both bores in one setup and check center distance before shipment.
Covers and housings need flat gasket faces and clean bolt-hole edges. We machine the gasket face and the bolt pattern on the same zero, then deburr every hole.
One-off brackets and adapters are quoted the same way as production runs. No minimum order quantity, and the file set carries over when the design is ready for a run.
A 3D model in STEP or IGES plus a 2D drawing with tolerances, material, and finish. If you only have a model, we can work from that and flag the features that need a tolerance call.
Mark which dimensions are critical. That lets us plan the setup and the inspection around the features that actually matter.
Yes. There is no minimum order quantity, so one part and a 10,000-part run go through the same process.
For prototypes we often start from billet and skip hard tooling. When the design is frozen, the same file set moves to the production run.
7075-T6 when stiffness and strength matter most, and the part will be anodized. 6061-T6 when you want easier machining, better weldability, or lower cost.
Both machine well. The choice comes down to load path and how the part is finished.
Light finishing passes, sharp tooling, and support on the unsupported side. We also leave stock so the part does not move while it is being cut.
If a wall is under 2 mm, we may suggest a small design change. A rib or a slightly thicker section often costs less than chasing the tolerance.
Anodizing in clear, colour, hardcoat, and conductive grades. Electroless nickel, zinc, silver, and gold plating. Powder coating and black oxide.
Bead blasting, tumbling, brushing, and polishing. Laser marking with a minimum character height of 1.5 mm.
Every order gets a raw material check, in-process monitoring, and a final inspection. That is 100% inspection before shipment, not sampling.
Dimensional reports, material certificates, and CMM results are available on request.
Uploads are kept secure, and we sign an NDA on request before files are shared.
Only the people who need the files to quote or machine the part see them.
Quote and free DFM analysis come back within 12 hours. Production can start within 24 hours of approval, and parts ship in 3–5 days after completion.
The exact schedule depends on part count and finishing. We confirm it with the quote.
