Just have 130 miles on 2014 Yamaha SR Viper XTX SE , the ride is very similar to the ac f8, controls are ac, the long track seems to hook up quick, very very nice ride , we did hit some rough trails and the sled handled great, ate the bumps up, tuning the suspension to my riding will come later, just getting broke in. Will comment more when more miles are added---very happy with the ride as of now!
