I have never adjusted suspension on any motorcycle i have ever owned. I honestly probably don't ride hard enough that it will ever be a problem but I figured as easy as the 2015 is to adjust preload I might as well at least set the sag. I have a question for those who have done theirs. I don't have the means to lift up the bike to get a baseline with the suspension unloaded. What were your measurements unloaded vs. the bike sitting with no rider. I figured if your numbers are fairly consistent I could take your averages and set my sag with just me and my wife helping. For example id everybody says between 5-10 mm I can just measure where mine sits without me then sit on it and adjust for another 25mm making total sag 30-35mm. I know it won't be accurate but it will be better than it is now which is wherever the dealer set it beacuse the bike is new. I will take it to a shop later and have it setup completely at a later date. Thanks in advance!
