What is the method for adjusting motorcycle chain tension?
4 Answers
Motorcycle chain tension adjustment method is: 1. Loosen the clamping nut under the frame, tighten the adjusting nut, adjust the rear disc brake pad to about 3mm from the rim, then tighten the clamping nut; 2. If components such as the brake plate, short pull rod, and rear pull tube are loosely fitted, or if the rear crank spring opening angle is too large with insufficient elasticity, loosen the brake tightening screw; 3. Use your left hand to lift the rear pull tube upward to bring the rear disc brake pad closer to the rim, then use your right hand to pull the handlebar's short pull rod downward to align the short pull rod and rear pull tube in a straight line, then tighten the brake tightening screw to adjust the small chain tension. The chain is a component of a motorcycle, which can be divided into structural types: 1. Motorcycle bushing chain; 2. Motorcycle roller chain; 3. Motorcycle sealed chain; 4. Silent chain.
I've been riding motorcycles for years, and adjusting chain tension is an essential skill. If the chain is too loose, it makes a lot of noise while riding and is prone to falling off; if it's too tight, it accelerates wear and increases costs. I usually use a center stand or side stand to lift the rear wheel off the ground, find the midpoint of the chain, and measure the tension by pushing it up and down—about 25-35 mm is ideal. Then, I loosen the rear axle nut with a wrench, turn the adjustment bolts to move the wheel backward, and tighten the nut once done. Remember to check both sides for consistency to avoid misalignment, and finally lubricate the chain to extend its lifespan. Beginners can use a ruler for more precise measurements, and always prioritize safety—avoid working on slopes to prevent the bike from sliding. Make it a habit to check every 500 km to save time and money.
I prefer adjusting the chain at home myself—it saves money and is straightforward. Just grab a regular wrench, park the bike on level ground, and check the chain tension by pushing the midpoint; the ideal slack is between 20-40mm. If it's too loose, loosen the nut, turn the adjustment bolt to move the wheel back, then retighten the nut. Don’t forget to lubricate the chain to prevent rust—I always test-ride a short distance afterward to ensure no odd noises. This method extends part life and cuts down on mechanic visits. Beginners should start with simple bike models and wear safety gloves and goggles to avoid injuries.
As a rider, I always pay attention to chain maintenance and regularly adjust the tension to prevent issues. Every few hundred kilometers, I check the chain's condition, measuring 25-30mm of vertical play—any looser and the chain may skip teeth, affecting control. After stopping securely, I adjust the tensioning bolts to ensure the rear wheel is aligned evenly, avoiding uneven wear. Lubricating the chain prevents dust and grime buildup—this habit extends chain life by years, saving money on replacement parts. Remember to perform adjustments safely on level ground without rushing.
