Single-Cylinder Engine Specification Example for Export Programmes: Racing Spec

This is a worked specification for single-cylinder engine in a racing spec 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 racing spec version exists because the duty cycle on export programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Cast Iron, 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.

Processes involved

  • injection moulding
  • gravity casting
  • surface grinding
  • electroplating
  • rubber vulcanisation
  • assembly line testing

Where this example applies

Programmes that run racing spec most often specify this build for export programmes. Related applications include rental motorcycles, trailer axles, municipal fleets, assembly programmes, light trucks.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 2.5 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 REACH-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 1000 pieces per line.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.

What testing is included?

Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
