Drive Chain for KTM EXC 300: Two-Piece Construction
This drive chain is built for the KTM EXC 300 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 two-piece construction programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: packing that arrived crushed at the port, or a fitment that looked right on paper and failed on the bench. 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 — Silicone 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 KTM EXC 300 mounting, not on a catalogue drawing.
- Finish — a sealed surface treatment 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
- heat treatment
- cold forging
- die casting
- powder coating
- CNC machining
- sintering
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 two-piece construction build is the one most often ordered for track days. Riders also fit it for mining sites, mountain roads, coastal delivery, night riding.
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 happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. ISO/TS 16949 documentation is issued with the shipment when your market requires it.
What is the minimum order quantity?
The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
