Silencer for Haojue 125: Sealed Unit
This silencer is built for the Haojue 125 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the sealed unit programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: a specification nobody had written down, or lead time that slipped twice before bulk started. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

What decides whether it lasts
- Material — Brass is the base; treat any substitution as a new approval.
- Hardness and heat treatment — recorded per lot, not per batch of paperwork.
- Fitment tolerance — checked on the actual Haojue 125 mounting, not on a catalogue drawing.
- Finish — anodising holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.
Where it is used
The sealed unit build is the one most often ordered for passenger transport. Riders also fit it for heavy load hauling, track days, long-distance touring, construction sites.
Ordering
- Confirm the model year and frame number before ordering.
- Approve a sample made from the actual bulk material.
- Fix the packing and marking at quotation stage.
- Book inspection before the balance payment, not after it.
Questions buyers ask
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO/TS 16949-compliant build instead of a fresh interpretation.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
