Motorcycle Identity
The useful identity set includes the CFMOTO model, model year, market version, original part number when available, and front, rear, or paired sprocket position.
Moto Sprocket
The six CFMOTO model pages below show listed front and rear 520 sprocket options, with model year and quantity used for fitment confirmation. Chain pitch, tooth count, and final-drive ratio define the direction of any gearing change. Material, wear, and inspection needs guide replacement planning.

Bike And Sprocket Fitment Checklist
Product ListThis page presents six featured CFMOTO moto sprocket options as a practical starting point within the broader motorcycle sprocket category.
Motomaxsfr can review a standard replacement or a drawing-based request, but a model label alone does not prove fitment across every model year, regional version, or modification.
Drive System Match
The drive-system check covers chain size, original front and rear tooth counts, chain line, tooth thickness, offset, spline or bolt pattern, mounting face, and available clearance.
Order Definition
The commercial specification includes quantity, original or modified gearing goal, surface or color preference, inspection needs, destination, and any drawing that controls the interface.
Product And Quote Route
The matching CFMOTO product below presents the listed 520 configuration, while the quote form carries the specification into a commercial response.
Tooth Count And Gearing Direction
Product ListFinal-drive ratio equals rear sprocket teeth divided by front sprocket teeth. Tooth changes set a direction, not a guaranteed result, because engine output, tire size, mass, aerodynamics, riding conditions, and electronic systems also influence the motorcycle.
| Configuration Direction | Common Tooth Change | Typical Effect | Checks Before Approval |
|---|---|---|---|
| Higher numerical ratio | Larger rear or smaller front | Usually favors stronger wheel torque and acceleration response, with higher engine speed for a given road speed. | Chain length, adjuster range, front-sprocket clearance, chain wrap, chain line, speed indication, and operating rpm. |
| Lower numerical ratio | Smaller rear or larger front | Usually favors lower engine speed at a given road speed, but may reduce acceleration response or make top gear harder to pull. | Engine load, clutch use, low-speed control, available power, chain length, clearance, speed indication, and legal limits. |
| Original ratio | Verified original front and rear tooth counts | Preserves the intended baseline when the correct model-year specification is confirmed. | Original equipment data, current modifications, wear condition, chain size, mounting interface, and alignment. |
Material, Wear, And Duty Review
Product ListThe linked CFMOTO records list 45# steel for the rear sprocket and 20CrMoTi steel for the front sprocket. Material names help define the starting specification, but they do not create a universal service-life promise: tooth geometry, heat treatment, surface condition, alignment, lubrication, load, contamination, and chain condition also affect wear.
| Inspection Area | Inspection Points | Decision Meaning |
|---|---|---|
| Sprocket teeth and body | Hooked or asymmetric teeth, chipped or missing teeth, cracks, excessive side wear, corrosion, loose mounting, runout, or damaged splines and bolt holes. | Structural damage or severe tooth wear requires replacement and investigation of the cause before a new part is fitted. |
| Chain condition | Specified elongation measurement, stiff links, damaged rollers or plates, displaced pins, missing seals, corrosion, abnormal noise, and correct lubrication. | A worn or damaged chain can load a new sprocket incorrectly; manufacturer-specific limits govern the decision instead of a universal mileage rule. |
| Complete final drive | Front and rear tooth counts, pitch, tooth thickness, chain line, alignment, slack, adjuster position, guards, swingarm clearance, and full-travel clearance. | The chain and both sprockets form one meshing system, so their combined condition determines whether the safe repair is one component or a matched set. |

Specification-Based Supply Terms
These planning bands structure the inquiry, while the written quotation controls final MOQ, price, lead time, packing, documents, and delivery terms.
One specification-confirmed sample provides the starting route. Sample charge and a 7–15 business day planning target are confirmed in the quotation.
A 100–499 unit planning band supports specification review. Unit pricing, inspection points, packing, and a 20–30 business day target remain quote-specific.
A 500+ unit planning band supports bulk sourcing. Negotiated pricing, capacity reservation, and a 25–40 business day target are finalized after forecast review.

Questions Buyers Ask Before Ordering
These answers identify the model, reference, documentation, and installation details that complete a purchasing review.
What Else Helps Confirm A CFMOTO Sprocket Fit?
The motorcycle model, year, and version can be supported by the original part number or clear photos of the current sprocket markings and mounting face when available. These references help resolve catalog differences before a quotation is finalized.
Are The Listed Tooth Counts An Automatic Fit For Every Model Year?
No. The listed front and rear tooth counts come from the linked product records and are selection starting points. Final fit is checked against the year, regional version, chain line, clearance, mounting pattern, and intended original or modified ratio.
Which Drawing Files Can I Upload For Review?
The drawing form accepts PDF, DWG, DXF, STEP, STP, JPG, JPEG, and PNG files up to 10 MB. The required quantity and a work email connect the reference to the commercial request.
Which Order Documents Can Be Discussed In The Quote?
A commercial invoice and packing list can be specified for shipment. Inspection reports, material evidence, certificates, traceability, and any customer-specific document format are listed in the written quotation when ordered.
Who Should Install A Motorcycle Sprocket?
Sprocket and chain installation is safety-critical work. A qualified motorcycle technician should follow the applicable service manual, verify fasteners and alignment, set chain slack, and check the completed drive through the suspension travel before use.
