Available in six tooth counts — Z9, Z10, Z11, Z12, Z13, and Z16 — the sprocket selection allows racers to adjust final drive ratio for different tracks, conditions, and class regulations. Each sprocket ships with the required mounting screws.\u003c\/p\u003e\n\u003cp\u003eSprocket selection is one of the most fundamental tuning adjustments on a KA100 kart. Fewer teeth (Z9, Z10) provide higher top speed for long straights, while more teeth (Z12, Z13) deliver stronger acceleration for tight, technical circuits. The Z16 is typically used for specific class or track configurations. Pair the engine sprocket with the appropriate rear axle sprocket for the correct overall gear ratio.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Type:\u003c\/strong\u003e #219\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Tooth Counts:\u003c\/strong\u003e Z9, Z10, Z11, Z12, Z13, Z16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Sprocket with mounting screws\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 sprocket per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMost KA100 racers carry at least two or three sprocket options to adjust gearing between practice and race sessions.
