These engines are pretty bulletproof, and designed to run at very high revs.
I often run long distances, 200 miles +, 2 up, meaning under a heavy load, at 60 mph or above. One of my Rebels has 49,000 miles on it. The other one I've just got barely 13,000.
There are some here with over 100,000.
You'll get more responses soon stating something similar. But it is VERY important to do your oil changes. Many do these every 1000 miles. I do it about 2×/season which isn't really enough.
