Outdoor Motorcycle Theme Wedding

Hi everyone, hopefully someone could help me out as well. The last post looks about 5 years old. I`m also planning a motorcycle themed wedding. There will be no limo, just the members of my fiancee`s bike club on bikes. I.ve searched around for party favors related to our theme but haven`t really seen anything "special" I`m loving all the ideas on this post as well. I am wearing a lace weding dress with a small train and my bridesmaids will be in traditional bridesmaid dresses. I seen some "biker boot" vases that I would like to use as centerpieces, just not sure of the color scheme. We`re Harley riders but I don`t really want to use the orange color so I`m thinking black and silver. Any ideas please let me know. Thanks in advance!
