Yamaha already has a 1050cc triple......it is in their Nytro snowmobile and is a great motor.
In fact on that motor you can get from Yamaha either a MC express super charger of turbo to bump the power to the 225hp range.
About time is shows up in a bike.
Yamaha's last attempt to switch motors between toys didn't go so well. The RX1 didn't last long
