I purchased the Yamaha 4 year warranty for 1000.00.Getting a YEs warranty from ride now is about impossible. They will do everything in there power to sell you an aftermarket warranty instead.
DO NOT buy an aftermarket third party warranty. The Yamaha YES warranty is one of the best in the business. The 4 yr warranty will run you around $1100 for a good deal.
If you want to purchase the warranty call Cochise Motorsports in Az. Ask for Doc. Other dealers can take car of you
