That is your choice and I am not knocking it if it makes you happy. Me, I much prefer to stick with lighter tents. 2.3 kilos (more like 5 pounds btw) is just more tent than I want to be burdened with. Where the terrain suits it, I sometimes even am inclined to skip the tent and take a bivy. I did take a 4 pound tent on one tour and might have been able to squeeze the bike in, but I didn't see any reason to do so. My bike stays outside with any gear that doesn't need to be in the tent (or in the bear box or bag) still packed in the panniers.
