The ZENIUM unit is an absolute state of the art and ready to race shock absorber developed by Donerre to fulfill the highest demands in motorcycle racing. This full adjustable damper has been released for production after extensive testing with professional teams and riders to reach an excellent performance level and outstanding durability and reliability, standards where all Donerre Products are known for.

Product sheet / pdf file

The ZENIUM dampers are available in different configurations for as well on-road and off-road application, all build to cope with the specific demands and conditions of the particular motorsport discipline. Calibration of the zero needle position in the adjust mechanisms and vacuuming of the oil with sophisticated equipment are standard integrated in the assembly process. This in combination with the use of high quality materials, advanced coatings, and close tolerated dimensions makes that each ZENIUM damper will always match the tested settings. An ingenious system makes that the external adjusting of compression damping does not influence the rebound damping characteristics and vise versa. Just as all other Donerre suspension units have of course also the ZENIUM dampers passed the modern shock dyno before they will be send out to the customer. Donerre offers a wide range of springs for the ZENIUM damper.
