The following suggested gear ratios are based on a combined kart and driver weight of 175kg, using a Briggs & Stratton LO206 engine (rev-limited) and Dunlop SL1A tyres. These ratios are recommendations only—optimal gearing may vary depending on factors such as weather conditions, kart setup, total weight, and driving style.
To keep things consistent, we’ve used a 17-tooth front sprocket as the baseline. As a general rule, a change of 1 tooth on the front is roughly equivalent to 4 teeth on the rear.
Example: 16/64 = 17/68 = 18/72
