Regina - advanced Enduro competition chains

The latest new products to come out of Regina’s northern Italy headquarters are these precision-engineered, 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 Gualdi, "giving riders the advantage of sapping less power in the drivetrain - resulting in a competitive edge on the track.
"Crucially, the Z-ring’s low profile allows the ZSE to be built to a narrow spec. 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 the entire Husqvarna, GasGas and TM ranges".
Manuel Lettenbichler, competing for the Red Bull KTM Factory Racing, won each single race of the Hard Enduro Championship in 2023 using Regina 520/135ZSE - "a proof of reliability and performance for top riders as well as any amateur enthusiast".
