The owners manual gives excellent instructions for adjusting suspension. Being light, 150 lbs/68 kilos, I softened up two clicks front and one click back and it's fine now. If I had the naked version I would have gone two clicks in the back as they come from the factory with different settings in the rear. You just have to make adjustments until you find the setting you like.
I weigh 10lbs more than you and I have my rear preload in the middle at #3 and the rebound at 1 turn back from full CW. I will need to get back on the front. However I will tell you that I like to go with a softer preload and a bit more rebound. It smooths out the bumps on some of the New England roads.
