Cf Moto builds around 900,000 engines a year and has for decades. At one time they build Polaris SXS's, Honda 90cc engines, KTM engines and a few others. In many countries, CF Moto is a top selling brand. They use elka shocks (not junk) Delphi fuel injection and Bosch electronics. None of which is junk. I'm guessing and reasonably certain very few if anyone here has ever driven a CF Moto but rather are basing their opinions on stereotypes.
Comparing it to a RZR 900S which I have been in several times, dollar for dollar, I would take the CF Moto every day of the week. Just as capable if not more due to its locking front diff, and engine braking. Comes with the extras that polaris charges for and still costs 1000"s less.
any guesses on who created and trademarked the liquid cooled 4-stroke engines that led to today's modern power plants? Yup, CF Moto.
