Go-Kart Gear Ratio & Speed Calculator
Required Data Entry
Notes:
- Use realistic engine RPM (e.g. 2400–9000). Typical small engines are 3000–4000 RPM.
- Higher gear ratio = higher top speed (less torque/acceleration). Lower ratio = more acceleration.
- Clutches prefer = 35 mph; torque converters can work up to ~45 mph (flat terrain).
