Piston Ring Set for BMW R1250GS: High Performance
This piston ring set is built for the BMW R1250GS 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 high performance programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: inconsistent hardness between lots, or a supplier who changed material without saying so. 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 — Forged 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 BMW R1250GS mounting, not on a catalogue drawing.
- Finish — powder coating 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
- injection moulding
- shot blasting
- gravity casting

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.

Questions buyers ask
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.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SGS-compliant build instead of a fresh interpretation.
