I don't think Cat showed everything in their early release, I think there is more to come, maybe there is a new co built chassis to be unwrapped yet, could be what Yamaha models are going to be housed in, I would sooner like to see a new Yamaha chassis and begin the break away process from Cat, the NA 998 is around 112 hp its being used in Yamahas sport Side x Side, so putting that engine in the Viper will put the power down but they may be able to match with some tuning, I think they may have a new engine in the works possible a twin turbo or maybe use the new R1 engine.
