It's the creative idea of "Leanne" a homemaker in Chino Hills, CA who describes herself as a biologist-turned-baker. She made the cake with four 6" rounds. We would have preferred some kind of dark chocolate filling to resemble motor oil, and some "caked" up mud, for good measure, but that's just us.

I'm sure KTM enthusiasts could contact her for work.
