Quick answer: A motorcycle front sprocket wholesale RFQ should list the chain series, exact tooth count, bore option, motorcycle make/model/year, and clear photos of the sprocket and shaft interface. Treat each as a separate field. A matching bore or a familiar model name by itself does not confirm fitment.
For a distributor, one wrong front-sprocket option can create a mixed carton that cannot be allocated cleanly. The product label may show a chain series and tooth count, while the shaft bore, spline profile, thickness, or vehicle application still needs checking. The safest quote starts with the exact option you want and asks the supplier to confirm the missing fitment details in writing.
What should a wholesale front-sprocket RFQ specify?
Send enough information for the supplier to identify the same variant you intend to reorder. Keep the vehicle reference and the physical sprocket measurements together so the seller can compare them against the actual listing or drawing.
- Vehicle: make, model, year, engine code, and destination market. Add the OEM or stamped part reference if you have it.
- Chain series: write the series exactly as it appears on the old part or in the verified application record. The current VOBOM catalogue includes 420, 428, and 520 listings; do not assume one series is interchangeable with another.
- Tooth count: state the exact count you need. A listing range such as 13–17 teeth is not confirmation that every tooth count is available for every chain series.
- Bore and shaft interface: give the measured bore option and send a clear photo of both sides of the sprocket and the mating shaft. Ask the seller to confirm spline/profile, retention method, thickness, and offset against the actual application.
- Order line: specify quantity by option, packaging or label requirements, destination country/postcode, and whether you need a sample before the bulk order.
What do the current catalogue listings confirm?
These examples show why one short product code is not a complete fitment record. The details below are supplier-listed references for identification, not an independent fitment test. Confirm the exact combination, current availability, and MOQ in the written quotation.
Custom front sprockets: 420, 428, or 520 series
The catalogue listing names 420, 428, and 520 series and a 13–17 tooth range. It lists an MOQ of 3 pieces, but does not map every chain-series/tooth-count combination to a motorcycle model. Confirm the exact option and its application before placing a mixed or repeat order. See the custom 420/428/520 front-sprocket listing.
428-14T with 14 mm or 17 mm bore options
This listing names a 428-14T sprocket and offers 14 mm or 17 mm bore choices. Its product record does not provide a motorcycle make/model/year fitment chart, shaft spline or keyway pattern, or sprocket thickness. It lists an MOQ of 500 pieces; ask the supplier to reconfirm the selected bore option and current order terms. View the 428-14T 14/17 mm bore listing.
428-15T with 18 mm or 20 mm bore options
The off-road listing identifies a 428-15T front sprocket and 18 mm or 20 mm bore options. The record says tested motorcycle models are not identified and lists an MOQ of 500 pieces. Send the shaft photos and vehicle details so the seller can confirm whether the selected option matches your application. View the 428-15T 18/20 mm bore listing.
Why is bore diameter not enough to confirm fitment?
Bore is one measurement. The available catalogue descriptions also call out missing information such as shaft spline/profile, keyway pattern, sprocket thickness, and a fitment chart. Two parts can share a stated bore option while still needing different shaft-interface or spacing details. Do not approve a bulk order from the bore number alone.
For a reliable comparison, photograph the old sprocket from both sides, include a ruler or caliper in a separate measurement photo, and show the mating shaft or the relevant drawing. Ask the supplier to mark the confirmed bore, interface, thickness, and offset on the quote or drawing. If the source record does not establish a field, keep it marked “to confirm” rather than copying a guess into your purchase order.
How can buyers compare supplier quotes fairly?
Compare like with like. Put the chain series, tooth count, bore, and confirmed shaft interface on every quote line. Then check that the quoted MOQ and price apply to that exact option, not just to the general product family. Ask which material or finish is included only when the supplier has stated it for that SKU; do not carry a material name from one listing over to another.
For a first order, request a sample or a written drawing review before approving the full quantity. Confirm whether packing dimensions and weights describe one piece, one retail package, or a shipping carton. The current product records do not consistently state that scope, so the quotation should make it explicit. Freight should be calculated from the destination, quantity, and confirmed carton details.

Frequently asked questions
Does “428-14T” confirm that a sprocket fits my motorcycle?
No. It identifies the listing’s chain series and tooth count, but the catalogue page does not provide a verified model/year fitment chart. Send the vehicle reference and shaft photos and ask the supplier to confirm the exact option.
Can I choose a sprocket by bore size alone?
No. The listing itself says the shaft spline/profile, keyway pattern, thickness, and fitment chart are not supplied. Treat bore as one check in a broader fitment review.
Can I rely on the MOQ shown on a product page?
Use it as the listing’s current reference, then ask the supplier to reconfirm it for your selected bore, tooth count, quantity, and order date. A product-family MOQ may not apply to every option.
If your order covers a chain and both sprockets as a set, use our broader chain and sprocket wholesale RFQ checklist to list the complete order scope.
Request a fitment review before ordering
Send your vehicle details, old-part photos, requested chain series and tooth count, bore measurement, quantity, and destination. We will ask the seller to confirm the exact option and quote terms before you approve a bulk order. You can start from the custom front-sprocket listing, the 428-14T listing, or the 428-15T listing, or request a fitment review.
