Lose weight. The Honda GL1800 Gold Wing can get better mileage if the operator sheds a few pounds. Also consider removing all luxury items such as the back seat and any stickers.
Remove tassels. Discard any leather, pleather or plastic tassels to improve wind resistance. Duck your head behind the wind guard while riding.
Drive smart. Do not speed, accelerate rapidly or constantly break. Drive your motorcycle on the highway at 60 miles per hour break and stop when necessary. Consider using the cruise control function to ride at a constant speed.
Start the motorcycle only when you intend to ride it. Making loud noises with your motorcycle in neutral only burns your gas.
