Introduction: The Bane of Every Rider – Rust on Your Motorcycle Chain
Rust. The silent killer of motorcycle chains. It’s a common problem that plagues riders, especially those who live in humid climates or ride in wet conditions. Rust not only diminishes the aesthetic appeal of your bike, but it also severely compromises the performance and lifespan of your chain. A rusty chain can lead to increased friction, reduced power transfer, accelerated wear and tear, and ultimately, chain failure. Ignoring rust can be a costly mistake, potentially leading to accidents and expensive repairs. But fear not, fellow riders! This comprehensive guide will walk you through various methods on how to effectively remove rust from your motorcycle chain and keep it in top condition.
Why Does Rust Form on Motorcycle Chains?
Before diving into the solutions, it’s crucial to understand why rust forms in the first place. Rust, chemically known as iron oxide, is the result of a chemical reaction between iron (the primary component of most motorcycle chains), oxygen, and moisture. This process, known as oxidation, is accelerated by the presence of salt, acids, and other corrosive substances. Here’s a breakdown of the contributing factors:
- Exposure to Moisture: Rain, humidity, and washing your bike without properly drying the chain are major culprits. Water acts as a catalyst, speeding up the oxidation process.
- Lack of Lubrication: Chain lubricant creates a protective barrier against moisture and corrosive elements. When the lubricant wears off, the chain becomes vulnerable to rust.
- Road Salt and De-icers: During winter months, road salt and de-icing agents are used extensively to melt ice and snow. These substances are highly corrosive and can quickly cause rust to form on your chain.
- Neglect: Simply neglecting regular chain maintenance, such as cleaning and lubricating, will inevitably lead to rust formation.
Preventative Measures: Stop Rust Before It Starts
The best way to deal with rust is to prevent it from forming in the first place. Implementing a proactive maintenance routine can save you time, money, and headaches in the long run. Here are some essential preventative measures:
- Regular Cleaning: Clean your motorcycle chain regularly, especially after riding in wet conditions or on roads treated with salt. Use a dedicated chain cleaner or a mild degreaser.
- Proper Lubrication: Lubricate your chain after every cleaning and after riding in the rain. Use a high-quality chain lubricant specifically designed for motorcycles. Apply the lubricant evenly along the entire length of the chain.
- Chain Adjustment: Maintain proper chain tension. A loose chain is more prone to wear and tear and can accelerate rust formation. Refer to your motorcycle’s owner’s manual for the correct chain tension specifications.
- Storage: If you’re storing your motorcycle for an extended period, thoroughly clean and lubricate the chain before storage. Consider covering the bike to protect it from moisture and dust.
- Chain Wax vs. Chain Lube: Consider the pros and cons. Chain wax tends to stay on longer but can attract more dirt. Chain lube goes on wet and penetrates better but requires more frequent application. Choose the product that best suits your riding conditions and maintenance habits.
Methods for Removing Rust from a Motorcycle Chain
If rust has already taken hold of your chain, don’t despair! There are several effective methods you can use to remove it. The best method will depend on the severity of the rust and the tools you have available. Always remember to wear gloves and eye protection when working with chemicals and tools.
Method 1: WD-40 and a Wire Brush
This is a simple and readily available method for removing light surface rust. WD-40 is a multi-purpose lubricant and rust penetrant that can help loosen and dissolve rust. A wire brush will help to scrub away the loosened rust.
- Apply WD-40: Spray WD-40 liberally onto the rusty areas of the chain. Allow it to soak for at least 15-20 minutes to penetrate the rust.
