I have been involved in the OEM business my entire sales & marketing career & these agreements are created to maximize profits for both companies. Drop Merger from your vocabulary Merger is when Company A acquires Company B they downsize & merge to become 1 company & 1 brand. Yamaha & AC have agreed to a simple OEM agreement for period of time. Since all OEM agreements are solution oriented for the enduser, you the snowmobiler, to bring the best marriage of technologies in a final integrated product in this case a snowmobile. The Viper & its variations adds a new 2014 model to the Yamaha line up. No Yamaha model went away although it is possible in my mind in the future to obsolete the Nytro & the Vector if the Viper is very successful. Then again no way to know what Yamaha already has in their R&D pipeline so just conjecture on my behalf. OEM agreements can change & evolve overtime as the enduser drives the market which in turn maximizes profitability for both OEM principles. What is happening in this case is Yamaha is sharing their state of the art 4s engine technology with AC & AC in turn is sharing their chassis technology with Yamaha & the integrated Yamaha product is the Viper. Personally to me the Viper looks hot, has excellent chassis & engine technology & should be an excellent 135hp 4s sled. AC has not released their 2014 line up so we don't know how AC has applied Yamaha engines but should be an excellent sled as well. This where we are now plain & simple so don't go jumping to any conclusions that either of these companies are in trouble in any way this OEM agreement was signed to increase market share for both entities so lose your paranoia the spiders are NOT on the wall. With all the automobile industry people on this website please feel free to expand & explain OEM Agreements as they are so widely used in your industry & the vendors that sell you assembly equipment. I hope this helps many of you to better understand OEM Agreements & their purpose for you the enduser.
