I made this groomsmen motor cycle cake for my cousin. It is an exact replica of his dirt-bike, a Yamaha WR-450F. It is sculpted from German chocolate cake(his favorite), and has rice-crispy treats, fondant, licorice chains and wiring, has a light up Speedometer, and the front wheel spins.
The frame is made of wood (to support the angle/weight, and is one of the few things non edible. It was hard work, and hard to let go, but well worth it and so gratifying to see my cousin’s face.
