Using WD-40 as a chain lubricant on a motorcycle is a topic of debate among riders and experts. While WD-40 can provide temporary lubrication and help displace moisture, it is not designed specifically for long-term chain lubrication. Here are some points to consider:
Temporary lubrication: WD-40 can offer short-term lubrication benefits by penetrating and loosening rust or debris on the chain. It can help provide some protection against corrosion and assist in freeing up stiff links. However, its lubricating properties tend to be less durable compared to dedicated chain lubricants.
Limited adherence: WD-40 has a relatively thin consistency and can quickly evaporate. This means it may not adhere well to the chain, especially at higher speeds or in wet conditions. It may get flung off the chain, leaving it under-lubricated and prone to increased wear.
Attraction of debris: WD-40's sticky residue can attract dirt, dust, and other contaminants from the road. This accumulation can create a gritty, abrasive mixture that can accelerate chain wear and reduce its overall lifespan.
Chain maintenance: For optimal chain performance and longevity, it is generally recommended to use a dedicated motorcycle chain lubricant. These lubricants are designed specifically for motorcycle chains, providing better adherence, resistance to flinging, and long-lasting lubrication. They are formulated to withstand the high-speed and high-stress conditions experienced by motorcycle chains.
In summary, while WD-40 can be used as a temporary solution for cleaning or freeing up a stuck chain, it is not ideal as a long-term chain lubricant. It's best to use a dedicated motorcycle chain lubricant that is designed to provide proper lubrication and protection for the chain, enhancing its lifespan and performance.
