Chain 520x74 Swift Heavy Duty Supplied With Spring Link Only Recommended Upto 250CC Only

Swift Chain Heavy Duty

Swift Chain's uses steel that has been specially heat treated to make them more durable and of a higher strength than many other standard chains. The heavy duty chain uses a thicker inner plate than a standard chain of the same pitch.

If the original equipment chain was an O-Ring or X-Ring chain it must not be replaced with a non-O-Ring or non-X-Ring chain. It must be replaced with a sealed chain of equal or greater strength.
