Moonbeam is a historic brand of motorcycles.
The company name was M.R.P. Trading Co., Pall Mall, London.
This was an English company that had derived its name from the successful Sunbeam. The production, which consisted of motorcycles with 269 cc Villiers engines, remained limited and lasted only from 1920 to 1921. The choice for the Villiers engines was not illogical, because this built-in motor vehicle was the property of Charles Marston, the founder's son from Sunbeam.
