With the first round of the new MotoAmerica series quickly approaching on April 10, Yamaha has been hard at work tuning and refining its all-new YZF-R1 in order to do battle. Luckily for us, Yamaha has been recording its test sessions at Thunderhill Raceway in a series it calls, “R1 Road to Austin.”

In this, the fourth installment, we see Factory Yamaha riders Josh Hayes and Cameron Beaubier putting down some hot laps, discussing changes with each other and their respective teams, and we even see Josh Hayes testing the Launch Control System that allows the rider to achieve a near perfect clutch dump launch, every time. Check it out below.
