In reference to travelling at highway speeds. My bike is new, and has only 117 miles on it. In the manual, it states that during break-in, you should keep the bike below 4000rpm. I find this nearly impossible to do. I commute to work on my bike, and use a state highway to do it. How important is this? Do I just need to slow down? I dont want to hurt my bike, but I dont want a 30 mile trip to take 45 minutes either. Any help would be greatly appreciated.
