I ordered the air vents with the motorcycle Honda XRV 750 Africa Twin - 1999 in mind. They fit the front calipers as well as the rear caliper. After screwing in, there is a little bit of thread sticking out(this is for a small minus), which is covered by a blanking rubber. They successfully replace the original, which is twice as expensive in the service. To the aesthetics and solidity rather can not be complained about - no burrs, the layer of zinc is placed on well-prepared steel. When tightening, care should be taken to select a perfectly matching wrench, scratches and destruction of the zinc layer can result in the appearance of rust in a fairly short time due to the fact that the material is steel. The downgrade for the material is due to the fact that I would prefer stainless steel instead of steel and zinc.
