There’s a reason why people use high-pressure washers to clean cement and strip paint. The force of the water can beat many surfaces into submission. Also, high pressure washers can force water into places where it doesn’t belong on a motorcycle. Corrosion is a motorcycle’s biggest enemy. Water in electrical connections can cause intermittent issues. Water in bearings can lead to early failure. The same is true for your bike’s chain. Water forced past the O-rings of the chain will displace the lubricant sealed within the pins – which is a sure way to quickly wear out the chain and require a replacement.
