Rainey credits the wind more than the new frame: “The tailwind down the straight helped the Yamaha’s speed, but coming the other way I was able to use the wind to help get the bike to turn in.”
According to Rainey, it was the wind that contributed more significantly to the bike's speed than the newly designed frame. He notes that the tailwind helped increase speed, while using the wind in the opposite direction enabled him to steer the bike more effectively.
