Prior Motorcycles

A Brief History of the Marque

Prior motorcycles, scooters and mopeds were rebadged Sachs Hercules for the the British market. The name change was due to the existing British brand of Hercules bicycles.

The Prior Viscount scooter was a rebadged Hercules R200 sold in 1958, 1959 and possibly later. One source says the "Prior Viscount had the Messerschmidt bubble car engine with the reverse-running points taken out." (see below)

From mysterybike section:

The Prior Viscount had the Messerschmidt bubble car engine with the reverse-running points taken out. It seemed very fast after the little Lambretta but was only 10 bhp! I used to ride 30 miles along country roads from my home to help construct the Santa Pod Raceway each weekend (about 1963). The trip took 1.1/2 hours on the Lambretta but only 3/4 hour on the Prior!

There was also apparently a Prior Viscount/Hercules R200 1959
