It is used to mount the rear sprocket to the axle and maintain correct drive alignment between the engine, chain and rear axle assembly. Sold individually as a genuine OTK spare part.\u003c\/p\u003e\n\n\u003cp\u003eCorrect sprocket carrier fitment is fundamental to reliable kart performance. The sprocket carrier positions the rear sprocket on the axle and determines chain line, which directly affects drive efficiency, chain wear and overall chassis behaviour. Using the correct genuine OTK carrier for your axle diameter and chassis specification ensures the sprocket is held securely, the chain runs true and the drive system operates as intended. An incorrect or worn carrier can cause chain misalignment, premature wear and potential mechanical failure during a session.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine OTK spare part\u003c\/li\u003e\n\u003cli\u003eOTK part number: 0047.FA\u003c\/li\u003e\n\u003cli\u003eMagnesium construction for strength and low weight\u003c\/li\u003e\n\u003cli\u003e2-bolt \/ 2-screw fixing design for secure sprocket retention\u003c\/li\u003e\n\u003cli\u003eDouble-sided design allowing installation in different orientations\u003c\/li\u003e\n\u003cli\u003e50mm diameter — designed for 50mm rear axles\u003c\/li\u003e\n\u003cli\u003eMaintains correct chain line between engine, chain and rear axle assembly\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: OTK\u003c\/li\u003e\n\u003cli\u003ePart number: 0047.FA\u003c\/li\u003e\n\u003cli\u003eType: Sprocket carrier \/ sprocket hub\u003c\/li\u003e\n\u003cli\u003eMaterial: Magnesium\u003c\/li\u003e\n\u003cli\u003eAxle diameter: 50mm\u003c\/li\u003e\n\u003cli\u003eFixing: 2-bolt \/ 2-screw\u003c\/li\u003e\n\u003cli\u003eDesign: Double-sided\u003c\/li\u003e\n\u003cli\u003eQuantity: Sold individually\u003c\/li\u003e\n\u003cli\u003eSprocket, chain, sprocket protector, axle, axle keys and fittings are not included\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment note:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis sprocket carrier is designed for compatible OTK-based kart chassis using a 50mm rear axle.
