Mika Metals Factory Series Chains use exclusive next level bushings that slow elongation of the chain and increase chain life. They have the lowest amount of friction on the market, are extremely lightweight, and are simply the ultimate racing chain. The 428 chain has 130 links. We HIGHLY recommend the use of a master link press to press on the master link as the master link is designed not to have any play in it. 428 chains fit all brands of the 85 and supermini EXCEPT the Kawasaki and Honda.
