.48kg springs are very light, thats what we install in a 4 stroke ktm for riders who weigh in the range of 195 to 210 lbs, and this is on a ike that weighs around 230lbs less not including rider weight etc.
Springs keep the ride height in the position that the valve likes. There should be a spring chart but I have not seen one for the Adventure. You suspension tuners are like doctors and lawyers. Only tell them what they need to know. That's fine with me but it would be neat to see the recommended spring chart.
