*** I have a 2018 Kawasaki Versys 650. I recently purchased a NoMar motorcycle tire changer. (Love it!) I've always wanted to change my own tires and have never done so until now. I bought these 45 degree valve stems as I was having trouble placing the gauges and air jet between the stem, straight stems and brake rotors. I went with the 45 degree but after fitting it I think the next tire change will be with 90 degree bars. Cause - It is still somewhat difficult to fit a pressure gauge/air jet between the rotors and the valve stem. On top of that, those 45-degree stems hold air! I used pliers to pull the stakes through the hole to be planted. At first I was afraid I might pull the stem out of the rubber seal (they don't fit easily!) but they stayed in place and all is well! I would buy them again if I no longer needed them. Stem 90 degrees.
