The Kart Service 219 sprocket is a premium CNC-machined ERGAL 7075 T6 rear sprocket for direct-drive karts. Designed for smooth chain engagement, durability and precise gearing, it is available in standard and half-tooth sizes for competitive karting use.

The Kart Service 219 kart sprocket is a high-quality rear sprocket engineered for direct-drive karts running 219 pitch chain. Machined from solid ERGAL 7075 T6 aluminium alloy using CNC technology, each sprocket is produced to close tolerances and finished with a special galvanic coating to increase surface hardness and extend service life. Individual tooth finishing improves chain engagement and reduces wear, making this sprocket a reliable choice for competitive karting, testing and race use.

Sprocket selection plays a significant role in kart performance. The tooth count determines the final drive ratio, which directly affects acceleration, top speed and engine RPM across a given circuit. Choosing the correct sprocket for the conditions — whether that is a tight, technical track requiring more acceleration or a fast, flowing layout where top-end speed matters — allows drivers and mechanics to extract the best from the kart and engine combination. The Kart Service 219 sprocket range, covering both standard and half-tooth options, gives teams the flexibility to fine-tune gearing with precision.

Key features:

• Sold individually

Size options:

• Standard sprockets available from 63T to 87T
• 63T, 64T, 65T, 66T, 67T, 68T, 69T, 70T, 71T, 72T, 73T, 74T, 75T, 76T, 77T, 78T, 79T, 80T, 81T, 82T, 83T, 84T, 85T, 86T, 87T

Half-tooth gearing:

Half-tooth sprockets allow more precise gearing adjustment in situations where a full tooth change alters the ratio too significantly. They are particularly useful when fine-tuning for changing track conditions, tyre grip levels or engine characteristics. Half-tooth options are available from 69.5T to 78.5T.

• 69.5T, 70.5T, 71.5T, 72.5T, 73.5T, 74.5T, 75.5T, 76.5T, 77.5T, 78.5T
