For decades and generations, a strong partnership has been forged by Custom Chrome Europe and the Ness family. Cory and Zach Ness continue the tradition of the legendary Arlen Ness, by creating extraordinary custom parts and custom bikes! Only the best oils and lubricants are used to complete a beautiful Ness-built custom motorcycle – so, obviously we are very proud to have both Cory and Zach Ness using RevTech Oils for their custom bikes! RevTech Oils are available for most Harley-Davidson models, including the latest Milwaukee Eight powered models and all common 45° V-Twin aftermarket engines.
