Color of the plastics, frame, A-arms and seat...that’s about it for 14-2020. 2021 however, as atvman8351 stated, it was delayed so what changes if anything other than cosmetic exist is still up in the air. I doubt there will be any mechanical difference. If they were working on a wholesale change, I suspect it would have leaked by now.What’s the difference from the 2019 YFZ 450r and the 2020 YFZ 450r? Are they making any changes from the 2020 to the 2021?
