Also if you have a smartphone, there are a few options. On iPhone I used Harry's Laptimer and it automatically logs the laps. It's pretty sweet.
You using GoPro?
I have an old school Nokia flip phone. It isn't pretty but, I have dropped it well over 50 times and it is still going. I have seen the smart phone apps and they are pretty cool. Go Pro on the Buell and Contour HD on the ninja.
