Yep, you'll be so nervous the first couple of sessions you'll forget about technique. Don't worry about your street bike. I assume you will be in the beginner group. Just about everyone in that group uses their street bikes. Intermediate group still uses mainly street bikes with some race bikes/track bikes. I use my street bike in "racer" or advanced group with no problems ( I now have an R6 race bike though). Have fun and make a check list of what you are going to bring to the track.
