Timing Chain for SYM Jet 14: Heavy Duty
This timing chain is built for the SYM Jet 14 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 heavy duty programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: reorders that did not match the approved sample, or packing that arrived crushed at the port. 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 — PVC Coated Fabric 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 SYM Jet 14 mounting, not on a catalogue drawing.
- Finish — a sealed surface treatment holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
Where it is used
The heavy duty build is the one most often ordered for weekend riding. Riders also fit it for wet weather riding, food delivery, mining sites, delivery fleets.
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.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ECE R90-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
