They’ve been trying to destroy us for 50 days, but the UA people are heroically resisting. We fear nothing, we know what we’re fighting for. We are brave enough to put an end to evil. Stop feeding the RU military machine. Help UA with weapons. Then peace & good will win faster. pic.twitter.com/WdDbZsvZ4e— Володимир Зеленський (@ZelenskyyUa) April 14, 2022
A Brief History of the Marque
The Santagostino brothers built motorcycles fitted with JAP and Blackburne engines of 350 and 500cc.
A 1922 Modelo Super 132cc two-stroke has "Royal Super" embossed on the rhs engine cover, so they may also have built their own engines. This model has chain drive from the engine, a second chain for the pedals, and a hand change on the petrol tank. There is no evidence of a front brake, but it may have had a drum rear brake activated by a lever on the handlebar.
