Yup, helmet required.

In a lovely design juxtaposition, this custom motorcycle features a pair of jet engines mounted to a frame modeled after a 1929 Harley-Davidson design. It can reach 200 MPH, and in truly Harley fashion, does so loudly…

This bike, which the owner claims is the only one in the world powered with two jet engines, is currently for sale on eBay.
