Engine Speed (\( V_e = \frac{0.333 \cdot R \cdot N_e}{I} \)):

Where:

• \( V_e \) is the engine speed, in kilometers per hour (km/hr).
• \( R \) is the diameter of the wheel, in meters.
• \( N_e \) is the engine speed, in revolutions per minute (RPM).
• \( I \) is the reduction ratio (1st gear = 4.48, 4th gear = 1.45).
