Quick answer: A clear motorcycle chain-and-sprocket RFQ identifies the exact motorcycle and lists the drive chain, front sprocket, rear sprocket and kit contents separately. Ask the supplier to confirm chain pitch and link count, sprocket tooth counts and mounting details, exact fitment, MOQ, packing and availability in writing. A tooth range or chain-size label on one product page does not prove that a complete kit fits your motorcycle.
This guide uses a current VOBOM front-sprocket listing as an example. Its title lists 420 / 428 / 520 series and a 13–17 tooth range; the listing itself asks buyers to send bike, chain and shaft details to confirm the exact option, MOQ and freight. Treat those as catalogue fields to verify, not universal fitment coverage.
Key takeaways: Give the supplier the make, model, year, market and variant; separate each component and quantity; mark unknown specifications as “please confirm”; and ask for the exact kit contents, sample scope, quote basis and shipping information. The linked VOBOM sprocket and chain-link listings currently show out-of-stock status, so confirm availability before relying on a quotation.
1. Identify the exact motorcycle before discussing parts
“Chain set for a Honda” is not enough to approve a bulk order. A model name can cover different years, markets, engine versions and revisions. Send the supplier one line for each application and include the evidence you have.
- Bike identity: manufacturer, model, model year, engine size, market and variant or frame/model code.
- Reference: OEM part number, supplier catalogue reference, or clear photos of the existing chain and sprockets, including visible markings.
- Order split: quantity for each bike and each component. Do not combine different applications into one line.
- Destination and packout: destination country, required retail or neutral packaging, labels and carton details that affect the quotation.
If you do not have an OEM number, say so and ask what additional evidence the supplier needs. Do not send a VIN or other sensitive identifier by default; provide only what is necessary to identify the application, and use a private channel if a supplier explains why more information is needed.
2. Separate the chain, front sprocket, rear sprocket and kit
A “chain set” can mean a chain only, sprockets only, or a complete kit. Put every requested item on its own line so two suppliers quote the same scope.
| RFQ line | What to provide or ask the supplier to confirm |
|---|---|
| Drive chain | Reference or requested series; pitch and link count if verified; chain type or grade; connecting-link inclusion; exact application. |
| Front sprocket | Part reference or tooth count; bore, spline or mounting details required for the application; material and finish only if specified. |
| Rear sprocket | Part reference or tooth count; mounting pattern and carrier details; material and finish only if specified. |
| Complete kit | Whether the quote includes chain, front and rear sprockets, connecting link, fasteners and any other listed parts. |
One VOBOM catalogue page lists a front-sprocket range of 420 / 428 / 520 and 13–17 teeth. It does not establish that every series, tooth count, bore and bike combination is one interchangeable option. Link the exact product in your RFQ, then ask the supplier to confirm the selected configuration and included items.
3. Ask for a written fitment check—not a broad compatibility claim
Request confirmation against the exact model year, market and variant you supplied. Ask the supplier to identify the reference used for the check and call out any unresolved difference. Phrases such as “universal,” “fits many bikes” or “same size” do not tell you whether chain length, sprocket mounting and included components match your application.
A current JT Sprockets catalogue entry for a 2026 Honda CRF450 RWE presents front and rear sprocket options separately from chain pitch and length, and advises buyers to consult the vehicle manufacturer’s manual for the correct chain type and grade. This illustrates how the fields can be separated; it is not fitment evidence for a VOBOM item or another motorcycle. Use your bike’s manual and ask the supplier to verify the actual references.
- Which exact model code, year and market does the offer cover?
- Which chain pitch and link count are included, and who confirmed those values?
- What are the front and rear tooth counts, references and mounting details?
- Are any changes or conversions included, or is the offer for a standard replacement?
4. Make supplier quotations comparable
Ask every supplier to quote against the same item list, quantities and destination. A lower unit price may cover a chain only while another quotation includes three components, a connecting link or retail packaging.
- MOQ by SKU, variant or application—not only a combined order total.
- Unit price at the requested quantity and any useful price breaks.
- Whether samples are available, what each sample contains, and any separate sample charge.
- Lead time and the event from which it is counted, such as approved sample or deposit.
- Included packaging, optional retail packaging, label requirements and carton measurements to confirm.
- Shipping basis and destination assumptions; keep freight separate if it is not included.
- Quotation validity and payment terms stated by the supplier.
Ask the supplier to show the quote by component and state whether the connecting link, hardware and packaging are included. That makes omissions visible before you compare totals.
5. Approve a sample and purchase-order revision against the same checklist
If a sample is available and needed for your order, compare it with the written quotation and application evidence. Record the supplier part number or revision, the parts received, visible markings, fitment points to check and the packaging agreed for the order. Ask the supplier to correct the quotation if the sample or kit contents differ from the RFQ.
Carry the approved references, quantities by application, kit contents, packing and agreed inspection points into the purchase order. A sample review helps verify the selected configuration; it does not replace any independent test or market document your business requires.

Frequently asked questions
Are 420, 428 and 520 chain series interchangeable?
Do not treat a series label as proof of interchangeability. Ask the supplier to verify the chain and both sprockets against the exact motorcycle and the references you provide.
Does a 13–17 tooth listing mean every sprocket in that range fits my bike?
No. The VOBOM listing describes a range in its title; it does not prove that every tooth count, bore and mounting option fits every motorcycle. Send the exact bike and shaft details and request confirmation for the selected option.
Does the front-sprocket page include the chain and rear sprocket?
Do not assume so. The cited VOBOM page is a front-sprocket listing. Ask for a component-by-component quote and have the supplier state exactly what any kit includes.
What should I send if I do not know the chain pitch or link count?
Send the bike identity, any OEM or catalogue reference, and clear photos of the existing parts and markings. Label unknown fields “please confirm” and ask the supplier what additional measurement or reference is needed.
Can a supplier quotation confirm stock and delivery?
Only the supplier can confirm current availability, lead time and shipping terms for the selected order. The linked VOBOM product pages currently show out-of-stock status, so request updated availability and freight confirmation before committing.
