Yes, still Yamaha chassis. Refinements include new plastics and new fit and finish to the plastics. Also, the motor is totally designed from the ground up by Yamaha which includes fuel injection and all electrical, it's all totally Yamaha engineered when it comes to the drive train. Also, the individual throttle bodies is huge, this is where the instant throttle response and and instant recovery come from. Yamaha did the turbo to Yamaha standards, they got it right. Also, it's more than 180 HP. We all know the MPI runs 180 HP and this unit has no problem handling the MPI. You can get out of the throttle and get back in it and still pass up the MPI. It works very well. You guys are welcome

I did not get a chance to ride it in the powder, conditions didn't permit it. Sorry, wish I could help more there.
