Wanted to post this information as I could not find anything when my 3 year old requested a motorcyle party.Here is what I came up with. Wilton makes motorcycle pans to make your own cake. Worked great! I found black & white racing striped plates and napkins to go with the theme. I was able to find a motorcycle pinata which had a Harley guy on it from the internet. It was soo cool! I ordered toy motorcycle pull back toys in bulk on the internet for goody bags. I included Harley Davidson temp tattoos in the goody bag. I was also able to find motorcycle stickers at Party city. I asked my friend who had a motorcyle to come by for the party and he offered to give older kids rides up and down the street. The morning of the party we took my son to breakfast at Marcus Dairy in Danbury where motorcyclists congregate on Sundays to compare bikes. He thought they came for his special day! It worked out great. You have to be inventive there is nothing out there unfortunately for this theme that would make it easier. Good luck!
