This would be for factory tires, springs, etc. I thought that I had heard somewhere it was 222kg?The Gross Vehicle Weight Rating is limited by the tires. Suspension springs can be changed to handle a lot more load than just the rider, passenger, luggage, fuel, extra gas can, trailer tongue weight, etc, etc, etc. What tires you want on it will give you the max load.
