Got on the expressway yesterday night just to see how the headlights hold up in the dark. I started my ride with a little bit of a headache but by the time was done my head was killing me. The speed limit here is 75 and I did that, maybe even 80 in some places. The ride was really stiff at about 70 and kinda took the enjoyment out of it for me. I plan on riding for about 200 miles on that same expressway in a week and was hoping there was something I could do to give it a softer ride. I weigh 240 lbs. Ive never adjusted the springs and I dont do anything on the bike besides ride it, Im not taking any aggressive turns or twisties or anything like that. Any recomendations?
