Record the chain identification and joining link

Provide the chain size marking, specific chain model or construction requirement and required link count where known. Include the joining-link reference or type as its own item. Chain size alone does not define every chain type or its suitability.

• Photograph readable chain markings and the existing package label if available.
• If markings are missing, identify that gap and include available measurements with their source and units.
• State whether the connecting link must be included; do not assume a different link model is interchangeable.

Identify the front and rear sprockets separately

List the front tooth count and rear tooth count in separate fields, with the corresponding part references. Provide the motorcycle model and year, and explain whether the installed drive setup has changed. A requested gearing change should be described as a new requirement, not assumed to be a direct replacement.

Attach the mounting details to the correct sprocket

Show the front sprocket’s shaft or spline arrangement and retaining features. For the rear, show the centre opening and fixing holes. Include known mounting dimensions, thickness and offset on a labelled drawing or photograph. Similar tooth counts and outline shapes are insufficient to verify fitment.

Make the kit contents and quantities explicit

List the chain, front sprocket, rear sprocket and joining link with one required quantity for each. State separately whether any fasteners or other items are needed. Add the quantity of complete sets, destination and packaging needs. Keep unknown references visible in the request instead of substituting dimensions from another model.
