Rear Sprocket for KTM RC 390: Low Maintenance Version

Rear Sprocket for KTM RC 390: Low Maintenance Version

This rear sprocket is built for the KTM RC 390 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 low maintenance version programme stable once it moves from first order to repeat order.

Most buyers come to us after something went wrong: lead time that slipped twice before bulk started, or packing that arrived crushed at the port. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

Specification

What decides whether it lasts

• Material — Anodised Aluminium 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 RC 390 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

• ultrasonic cleaning
• assembly line testing
• rubber vulcanisation
• die casting
• heat treatment
• anodising

Fitment notes

Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.

Where it is used

Ordering

1. Confirm the model year and frame number before ordering.
2. Approve a sample made from the actual bulk material.
3. Fix the packing and marking at quotation stage.

Questions buyers ask

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.

What is the minimum order quantity?

The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

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.

What testing is included?

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