Ahh!!! After buying a couple of zero meter bikes and a car (and having the same question as yours each time), my research on this topic concluded the following:
- This term that is called "Running" has a proper name i.e. "Engine Break-in" or "Run-in".
- By Definition, the goal of modern engine break-ins is the settling of piston rings into an engine's cylinder wall.
- A cylinder wall is not perfectly smooth but has a deliberate slight roughness to help oil adhesion. As the engine is powered up, the piston rings between the pistons and cylinder wall will begin to seal against the wall's small ridges.
- So the proper sealing or setting of rings is quite necessary, failing to do so will result in early engine repair.
- Now, how to properly break-in an engine is a controversial topic. There are different schools of thought on this topic. Many emphasize that normal and smooth driving is the way to break-in an engine while many other believe that harsh driving is the proper way to seal rings against piston walls.
- What I do for my new vehicle is follow the instructions on user manual of that vehicle. Manufacturer of your vehicle knows better than everyone else what is the proper way of breaking-in an engine.
- I followed the instructions (for the stated Kilometers) of the user manual of my car when I purchased it that stated:
a. Don't drive the car on constant speeds
b. Avoid harsh breaking
c. Avoid running the car on slow speed on higher gear
So I would suggest you to follow your user manual strictly on how to properly break-in your engine. If you are unable to find the instructions, avoid driving it at constant speed. Avoid immediate speeding or breaking. I hope this helps clear your mind.
- Your question is quite ambiguous when you haven't stated which bike are you talking about. Do mention your vehicle when asking Question.
