Three radiators broken in my raptor 700 2017.

Hello, I hope you are well. I wanted to ask you about a problem I am having right now on my 2017 Yamaha Raptor 700 Blaze Orange. About 4 months ago the OEM radiator on the bike started leaking coolant from a corner on the back of the radiator and all the coolant went back into the container. reserve... I thought it was from some hit with a stone or something similar and I decided to buy a larger aluminum one that is sold on eBay. Two weeks ago it began to break and a lot of coolant came out on the floor of my garage and again all the coolant was returned to the reserve tank, I decided to change it again, buy a new one from another brand and what was in the Top 5 One of the best sellers on eBay and yesterday I went for a ride and it started leaking again and obviously the coolant went back into the reserve container. The fan works because every time I take a ride I hear it come on and also in performance I only have a UNI high flow air filter and when I changed the last radiator I swapped the OEM exhaust for the Empire Industries dual exhaust. What do you think may be happening? Greetings.
