Last year I purchased a 2015 Polaris 570. It does not have an engine braking system. I’m very satisfied with the machine. I recently purchased a 2016 Polaris 570 that comes with the EBS Engine Braking System. My first ride was a 42 mile loop in an Idaho mountain area. I was very disappointed with the braking system. It locked the wheels on the downhills. I am 66 years old and have ridden motorcycles and ATV’s my entire life. I raced moto-cross in my younger years. I would consider the Engine Braking System on the 570’s to be dangerous for someone with limited ATV experience. I have returned the 570 to the dealer, and am waiting a reply from the factory. Hopefully, something can be done to disable the EBS.
