The 2017 EX owners manual says 300 miles. My salesman, who used to be a Honda technician, says the engines are all run on a dyno and not to worry about break-in. I have no clue if that is true. I just passed 300 miles and I am now getting more aggressive. I always go easy until the engine has a chance to build some heat.
