Motorbike Chain Lock Specification Example for Rental Motorcycles: Sealed Unit
Motorbike Chain Lock Specification Example for Rental Motorcycles: Sealed Unit
This is a worked specification for motorbike chain lock in a sealed unit programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The sealed unit version exists because the duty cycle on rental motorcycles is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

- Fix the base material in writing — PU Leather, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- anodising
- sintering
- assembly line testing
- robot welding
- die casting
- electroplating
Where this example applies
Programmes that run sealed unit most often specify this build for rental motorcycles. Related applications include workshop replacements, assembly programmes, light trucks, fleet maintenance, long-haul trucks.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
What testing is included?
Standard lots ship with dimensional and hardness reports. IATF 16949 documentation is issued with the shipment when your market requires it.
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.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the IATF 16949-compliant build instead of a fresh interpretation.
Ask for the current catalogue and the specification sheet for this line.
