The Black Pearl is an incredibly badass vehicle, constructed by Revatu Customs, that is best described as half-motorbike, half-locomotive. Named the Black Pearl, this motorbike is powered by a steam engine. It's a fully functioning motorbike, even if it's not exactly the quickest.
The motorbike is unabashedly inspired by locomotives, and this is obvious all over. The transmission, a crankshaft that rotates the rear wheel using an eccentric pivot, pays tribute to steam train engines both visually and from a mechanical engineering standpoint. This motorbike is even fitted with a bell and steam horn.
With a top speed of 8 km/h, the Revatu Customs creation isn't the best bet for a race. However it's still an engineering marvel that pays tribute to one of the most important transportation innovations in human history.
