About Chain Sprockets

Both your motorcycle and bicycle require regular inspections and maintenance to keep them on the road. An integral part of this inspection revolves around making sure the chain sprocket is in working order. This part looks like a gear and holds the chain in place with its teeth. Many things can happen to this part, notably wear and tear from use. Too little or too much slack in the chain could cause broken teeth, or worse, a broken chain. This can wreak havoc, especially in a motorcycle's engine. If upon inspection the parts are worn, purchase a new chain and sprocket kit to replace the old one. In a bicycle, you have the option of changing the gear ratio by varying the tooth count on the bicycle chain sprocket. A bicycle with multiple gears does this automatically when you change gears. With a fixed gear bike, you would have to purchase a new chain sprocket to change the gear ratio. Fortunately, you have the choice of many types and sizes of sprockets on eBay.
