Regina - advanced Enduro competition chains
The latest new products to come out of Regina ’ s northern Italy headquarters are these precisionengineered , high performance 520 / 135ZSE and 428 / 126ZSE Enduro chain options . The ZSE ’ s Z-ring flexes into place as the chain is assembled , creating a spring effect that keeps a durable , strong seal over time - trapping lubricant between the plates to reduce friction and keep the chain running smoothly . " The result is the best light-running chain available on the market today ," says Sales Director Federico
" Always on the cutting edge of clutch technology for the past 75 years ," California based Barnett Clutches has announced new K22 Kevlar and C22 Carbon clutch friction materials .

Even with the security and longevity of the seal , the ZSE ’ s width is within half a millimetre of some unsealed chains - this means that the ZSE can be used on machines where a normal O- ring chain might not fit ." Regina made sure to apply its knowledge and experience to the advanced design and specification of the rest of the chain ’ s components too . For example , the plates on the ZSE are high-carbon alloy steel , shot-peened and gold colour , with solid bushings and high-quality materials used throughout . Each box of the 520 version will have three connecting links included : one quad rivet type , one chamfering rivet type and one clip type for easy fitting . " The 520 ZSE chain has been engineered and developed alongside top Enduro racing teams around the world , which is why this chain is already OEM equipment on many off-road models such as
