Which of these will help reduce environmental harm caused by your motorcycle?

Explanation: Engines that burn fossil fuels produce exhaust emissions that are harmful to health. The harder you make the engine work, the more emissions it will produce. Engines also use more fuel and produce higher levels of emissions when they're cold. Anything you can do to reduce your use of fossil fuels will help the environment.
