The first Premier motorcycle was introduced
to the public at the Stanley Show, in november 1908.
Up to 1910 Premier used the White & Poppe engine,
from 1911, an engine of their own design was used.
1911 Premier onbekend, 500cc
This 1911 design doesn't completely follow
1911 practice, it has a unique feature namely
an extra exhaust valve. This spring- loaded
valve is situated at the bottom of the cylinder
and te idea behind the design is that it
enhances the cooling of the engine by providing
an extra escape for the hot exhaust gases.
There is a clutch in the rear hub to make
smooth acceleration from standstill possible.
