Here's how I did it for an upcoming short film:
Took a standard coffee can, cut out a 2" hole in the bottom, wrapped light weight foam around a Shure SM57 microphone, and put it in the can with the xlr input sticking out the hole, leaving about an inch and a half of space between the mic's capsule and the open end of the can. The microphone is essentially floating freely in the foam without touching the sides of the can.
I then put two nylon stockings over the open end to act as wind jammers. Originally I wanted to get it under the tail, but there wasn't enough space above the wheel. Instead I zip-tied it to the passenger footpegs and aimed it at the exhaust. In my case, I have an Ex Box, should you have cans simply turn the contraption around.
Amazingly no wind noise or vibrations, nice deep sound, and with a little eq it will sound even better. A coworkers snagged some photos of the contraption. I used a Zoom H4N recorder in the backpack.
I promise I will post the final video with the sounds as soon as it's done in a couple weeks.

Let me add this photo was during a test in a parking lot, I do wear a leather jacket when in traffic.
And it sounds like? Where's our clip man!?
What coolness are you going to be working that in on?
This is for a short animated film that should hit the festival circuit in April, supposedly it's being looked at by Sony and Dreamworks.
i've still got some work to do on the files and I'm not done recording, gotta take the bike out when there is less traffic. I'll post a clip shortly.
What software are you guys using for the animation work?
I'm actually not too familiar with their systems, but I'll ask the director next time we talk.
