Fairly positive that this not applicable to everyone, but I was having a problem trying to carry a standard size thermos bottle in my 2023 Zforce 800 Trail. The problem was that the two cup holders were too small to accept a standard size 40oz thermos like the Thermoflask. Found a large Adapter that would hold a 40oz bottle at Kemimoto (SKU: B0113-10601BK). The only problem was that the adapter would not go all the way into the cup holder due to the rubber insert in the cup holder. Wasn't too much of a problem to remove the rubber insert, it is held in place by two rubber tabs in the bottom of the insert and pulls out with a little persuasion.
