Motorcycle portraits. Help!

I have been asked to be the backup photographer at a Bike Ralley. Really cool, I think, but me concerns after reading lots of posts on this site, is to keep my reflection in the chrome not an issue. Any advice would be great. I have a Sigma telephoto, the kit 18-55 and a canon 35-80 (i do beleive) I think the kit lens should be fine and I am thinking of renting a large canopy to have nice non-distractrive shots, almost like a mini studio, PLUS its at 11-12 noon, so major sun in Iowa. Also, andy posing ideas: sitting on the bike, leaning against it? These arent glamor, just dudes and dudettes and their bikes, but I want to do them justice.

Thanks in advance.

best advice i can gove for static shots, is get down low for a few frames... it's been the biggest step forward i've had in my shots.

Here's my suggestions....First is to keep yourself out of the reflection in the chrome and paint; you can do this by using a long lens and moving a few feet left or right. Next, shooting at mid day will bring lots of glare so bring a good polorizer and check it. Keep an eye on shaddows. When I shot for HOT BIKE they liked to see lots of people riding shots especially smiles! That shows having a good time. Keep an eye on your background, and take lots of shots at different angles. A good shot of a big biker stuffing his mouth always works as well as a cute biker chick doin what she does best...Have fun and shoot a millian shots to get that select few that will make you a hero.
