I never managed to drag a knee but track days are awesome. Yamaha used to do free demo days on their brand new bikes - I did an unintentional wheelie the first lap on an R1 and later discovered that section of Road Atlanta is called wheelie hill. I much preferred the R6 being able to wring it out and still feel safe. Also the FZ1 was sensational doing 150mph sitting upright with barely any wind buffering your helmet.The experience of hitting in the black at 600yds the first time with an old K31 with clamp-on scope mount and $175 scope I liken to the first time I did a motorcycle track day and was able to drag my knee through a corner.
Both times giggled like a school girl...
