What happens if bike chain is tight?

When a motorcycle chain is too tight, it’ll put stress on several components of the bike and cause the sprockets to wear faster, make the engine work harder, and cause the suspension to be tight and uncomfortable. Ultimately, a tight chain on a motorcycle may break leaving you with no power.

How do I know if my bike chain is too loose?

On a derailleurless drivetrain, you should be able to lift the chain about 1/2 inch above its resting position at the middle of the chain above the gears. If the chain is too tight, you might feel and hear binding in the drivetrain as you pedal. If it is too loose, the chain could skip or drop, and you can see it sag.

What happens if your chain is too loose?

If the chain is too slack, it can skip over the tooth in the sprockets, This skipping over of teeth leads to uneven transmission of power from the engine to the wheel. As a result, the speed of the motorcycle will unevenly oscillate without any intervention from the rider.
