Engine Assembly Specification Example for Off-Road Bikes: Off-Road Version

This is a worked specification for engine assembly in a off-road version 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 off-road version version exists because the duty cycle on off-road bikes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — ABS Plastic, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Where this example applies

Programmes that run off-road version most often specify this build for off-road bikes. Related applications include three-wheelers, assembly programmes, light trucks, workshop replacements, passenger cars.

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

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 is the minimum order quantity?

The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

How long does sampling take?

Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.

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.
