I used a GoPro Wide Camera on '03 Yamaha R1 at a trackday at Sears Point / Infineon Raceway. This was the only clean lap (without any slower riders in front of me) that I got in during my final session of the day. I was probably riding at about 85% since this was my first time at Sears Point, and I needed my motorcycle the next day to ride into work! Still, I'm happy with the lap time and I don't know how the AMA pros go 30 seconds a lap faster?!?!
1:39s are what the daytona sportbik guys do...
