The specifications should include a minimum ground clearance of 155mm, suitable tires measuring 120/70-12, and an effective oil brake system with disc options.

Total weight should not exceed 240kg, while ensuring that the max designed gross weight is around 280kg, and should allow for SKD packaging of 75 sets in a 40HQ container.
