Neil Charlton breaks down the essentials of motorcycle chains with clear precision. A chain links the engine to the rear wheel, transmitting power through roller bearings between sprockets. It is simple but vital to performance.
There are four main types of chains: non-O-ring, O-ring, X-ring, and W-ring. O-ring, X-ring, and W-ring chains come packed with grease to protect bearings and reduce wear. The X-ring and W-ring designs were developed to improve lubrication retention while cutting friction losses.
Correct tension is key. A chain that’s too tight can damage bearings or plates. A slack chain can hit the swingarm. The ideal slack equals 1% of the sprocket center distance.
Lubrication depends on chain type. Standard chains benefit from deep cleaning and waxing. O-ring and similar chains do not need internal lubrication, as they’re sealed. Spray lubricants work best when applied sparingly to the inside run to cut noise and surface friction.
Pitch size depends on engine power. Race bikes often use a 520-pitch chain to lower drag. Sprockets should be replaced along with chains to prevent uneven wear.
Tight spots show wear or rust. They must be managed carefully when adjusting tension. A smooth, well-built chain means longer life and better power transfer.
My two cents…
Nice article. Motorcycle chains, the unsung heroes linking brute engine power to that spinning rear wheel. Neil Charlton lays it out, simple metal loops, roller bearings, sprockets, and somehow, you’re flying.
