i have a bone stock 2010 ultra classic. it has 2500 miles on it and this is my first Harley. Is this bike built to cruise at 80 mph or is that a bit much.. I was on the big slab today going 80 and pushing about 2900 rpms.. is that okay or am i stressing the engine...it seemed fine just need to know if i am damaging anything. i want to be able to cruise at between 70-80 mph on the interstate. what uprades do i need to get the performance i want which is to cruise easily at 75-80 mph...
