Turbocharged Engine Specification Example for Off-Road Bikes: Drilled and Slotted
Turbocharged Engine Specification Example for Off-Road Bikes: Drilled and Slotted
This is a worked specification for turbocharged engine in a drilled and slotted 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 drilled and slotted 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 a specification nobody had written down.

- Fix the base material in writing — Brass, in this example.
- List the dimensions that are actually controlled and the tolerance on each.

- State the inspection level and who pays when a lot fails.
Processes involved
- anodising
- die casting
- laser cutting
- ultrasonic cleaning
- powder coating
- electroplating
Where this example applies
Programmes that run drilled and slotted most often specify this build for off-road bikes. Related applications include agricultural trailers, boat trailers, light trucks, construction equipment, fleet maintenance.
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
What is the minimum order quantity?
The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 5 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.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
