I verified with the manufacturer for you that the weight is just 25 lbs for the Curt hitch that fits your 2020 Toyota C-HR, which is the following part:
- Curt Trailer Hitch Receiver # C11567
I have added a link below to a video install of this hitch on a similar model year C-HR for you to check out if you'd like to take a look. Additionally, if you plan on doing some light towing with your C-HR you'll need some other parts as well, which I'll list out for you.
