I am very familiar with race sag and it's effects on the bikes handling. It is critical to get the right sag for each rider. Where I get confused is the fact that most people (including me) measure vertically from the axle to the fender. Most how-to videos also show this method. When you look at a site like factory connection or look right in my rmz 250 user manual it specifically states it should be measured to the seat bolt. If you compare the results from the two methods you will see there is an 8-10 mm difference i.e. sag to fender would read 105mm and to seat bolt would be 95. To me it seems strange as the initial axle travel is actually out and then up. Factory Connection even warns not to measure vertically. There is a lot of debate on this and it seems like there should be a standard for such an important setting. It seems like Suzuki is right since they engineered the bike and obviously FC knows exactly what they are doing. I am going to test my bike set at the manufacturer recommended 105mm using both methods and see what feels right but I wanted to see if anyone has any input on this?
