First time taking Motorbike photos

I was up at Knockhill when there was a bike track session and this is my first real go at bikes.Found it more difficult to crop the images than with cars.Heres a few I'm happy with.The second rider looks like he has wings.

Nice job. I'm heading out tomorrow for my first attempt at race bikes. Any advice? What setup did you use to get these results ?

Cheers for the comment.I used a 400D with 70-210 f4 set on Tv .Panning at speeds between 1/50 and 1/125.I must have taken about 30 or so pics to get about 7 or 8 sharp ones ,so expect a few failures.

Thanks for the advice. I'll post a few in a couple of days to let you know how I made out.

Thats great JVBAKERO.Look forward to seeing the results.

Nice set.
