In addition to updating the throttle body joint to aluminum to transfer heat from the cylinder, they also gave the engine cases a heat treatment and utilize a stronger connecting rod to increase durability. The cylinder head port was raised 4mm providing a straighter intake while a 15mm shorter air funnel inside the airbox increase the airflow by a claimed 4. This gives the increased flow simulating a larger valve. They also came up with a new ECU calibration to make it all work together. Not only did Yamaha alter the power output, but also the shifting performance and a smoother clutch. They added a bushing on the shift arm inside of the engine case as well as grooves in the shift cam to add oil supply for less friction. Lastly for the transmission, 1st, 2nd, 3rd, and 5th gears were widened and the shifter position was lowered 5mm to match the frame changes.
