Vehicle Speedometer Tachometer Specification Example for Off-Road Bikes: Long Life Version

This is a worked specification for vehicle speedometer tachometer in a long life 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 long life 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 premature wear on the first batch.

How the example is built up

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

  • CNC machining
  • assembly line testing
  • rubber vulcanisation
  • precision stamping
  • heat treatment
  • anodising

Where this example applies

Programmes that run long life version most often specify this build for off-road bikes. Related applications include long-haul trucks, boat trailers, export programmes, assembly programmes, racing teams.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 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

What testing is included?

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

What is the minimum order quantity?

The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

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 long does sampling take?

Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
