Just purchased two of these Switchback machines. Coming from a 1997 Yamaha Exciter 2, 410cc. Had them both out today for my first ride of the season. OMG!!! I had NO IDEA technology had advanced this far, so smooth, so much power, easy steering and acceleration that will turn your knuckles white! It is a totally different riding position than the old Yammie. Did find out I need better riding gear now that I am up in the wind on these machines. Air penetrated my ski jacket like it was a tank top! Love the machine and am still at a loss for words on the difference between them. It was like being struck by lightning!
