I had a bike stuck like a mofo in a wheel chock once. after an hour of straining my back (that sucker was STUCK), a light bulb came on. I let some air out of the tire and she easily rolled out. Not sure if that will help for this situation but it sure did for me. So now I just put the front tire down to 20psi when I trailer the bike and it seems to work just fine. hope that helps someone!The HF motorcycle chock works for my 2014 Chieftain. However, I did cut 2” off of the top of the wheel chock because I felt it came to close to my fender and was concerned that while transporting the bike across the country hitting a big pothole could cause the front forks to compress enough to potentially cause contact. I was probably being overly cautious, but it was an easy modification to do with the $10 HF grinder.
My only complaint about the HF chock is that the weight of the bike makes getting the bike back out of the chock very difficult (and I am not a little guy). To get it out of the chock more easily, I insert a 2x4 below the front edge of the front tire and push the other end of the 2x4 down to lift the tire enough to make it easier to get my bike back out of the chock. Maybe someone has a better way of doing that.
