ZTechnik’s stainless steel Engine Guards will never rust like powder coated steel guards. They are carefully designed to allow clearance for oil changes or valve cover access, so they never need to be removed. Guards attach to the engine mounts – not the engine covers – to protect the engine heads and not destroy them. Integrated top brackets on each guard allow the rider to mount accessory lights, video cameras, or whatever they can imagine! Satin Finished Stainless Steel Note: Z7101 Engine Guards are not compatible with aftermarket exhaust headers, including ZTechnik's. Installing Z7101 Engine Guards will not allow for installation of O2 sensor with aftermarket exhaust headers.
