How to Adjust a Motorcycle Chain?

Motorcycle chain adjustment method: Ensure the chain adjusters on both sides are set to the same scale. After adjustment, rotate the rear wheel to check if the chain and sprocket are properly engaged to confirm correct adjustment. The chain tension should have about 25mm of vertical play. Finally, apply a small amount of engine oil to the chain. Motorcycle chains should be adjusted regularly as required, ensuring proper alignment and tension during the process. Alignment means keeping the sprockets and chain in a straight line, which prevents excessive wear and avoids chain derailment while riding.
I'm an old-timer with years of cycling experience, and adjusting the chain is like second nature to me. Every time before and after a ride, I habitually check the chain tension. First, I prop the bike steady on its center stand, then lightly press the middle section of the rear wheel chain with my finger—about 1 to 2 centimeters of up-and-down movement is just right. If it's too loose, I use a socket wrench to slightly loosen the rear axle nut, adjust the tension wheels on both sides to ensure the markings are evenly aligned, then tighten the nut again and check if the chain runs smoothly. Though it may seem simple, doing this carefully each time prevents the danger of chain derailment, making the ride safer and more worry-free. I often remind my friends that regular chain checks can extend its lifespan and reduce maintenance hassles.
I just started learning to ride a motorcycle not long ago, and I was really afraid of messing up when adjusting the chain. Simply put, you need to prepare some basic tools like a socket wrench. First, park the motorcycle on a flat surface and support it with a stand, then reach out to test the tightness of the chain at the midpoint: under normal conditions, the chain should easily move up and down about 10-15mm. If it's too loose or too tight, loosen the rear axle nut, use the wrench to slowly adjust the tensioner bolt, ensuring both sides are symmetrical before tightening the nut. After that, take a test ride to see if it runs smoothly. Remember not to force it—gentle operation can prevent damage, and this has saved me many trips to the repair shop.
