Tachometer for Dayun 150: Long Life Version
This tachometer is built for the Dayun 150 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the long life version programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: warranty claims traced back to a single lot, or reorders that did not match the approved sample. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

What decides whether it lasts
- Material — Natural Rubber is the base; treat any substitution as a new approval.
- Hardness and heat treatment — recorded per lot, not per batch of paperwork.
- Fitment tolerance — checked on the actual Dayun 150 mounting, not on a catalogue drawing.
- Finish — zinc plating holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.
Processes used on this line
- sintering
- electroplating
- shot blasting
- anodising
- surface grinding
- CNC machining
Fitment notes
Check whether the mounting points on your market version match the catalogue drawing — regional variants are the usual cause of a wrong first order.
Where it is used
The long life version build is the one most often ordered for wet weather riding. Riders also fit it for rental fleets, heavy load hauling, passenger transport, daily commuting.
Ordering
- Confirm the model year and frame number before ordering.
- Approve a sample made from the actual bulk material.
- Fix the packing and marking at quotation stage.
- Book inspection before the balance payment, not after it.
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.
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 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
