Vincent Black Prince Vincent Black Prince The Vincent Black Prince was a British motorcycle made between 1954 and 1955 by Vincent Motorcycles. A year before the factory closed in 1955, Vincent produced the enclosed range of Vincent Black Knight and Black Prince. Philip Vincent described it as a "two-wheeled Bentley", and the enclosed Vincents attracted a lot of attention at the November 1954 Earls Court show. Quality problems with early production of the glass-fibre mouldings necessitated a replacement supplier causing delays. The last Black Prince left the Vincent production line on Friday, 16 December 1955. Falling sales of the Series C Vincent motorcycles

The Black Prince had become redundant and the project was abandoned.

The only intact Black Prince is held by The Tank Museum in Bovington, UK; it is the fourth of the six prototypes that were built. It has recently been restored to running condition.
