Why is the motorcycle handlebar heavy?
1 Answers
Motorcycle handlebar heaviness is caused by poor lubrication of the steering stem bearings. A motorcycle, driven by a gasoline engine and steered by handlebars to control the front wheel, is a two or three-wheeled vehicle that is lightweight, flexible, and fast-moving. It is widely used for patrol, passenger and cargo transportation, and also serves as sports equipment.
