1947 Norton Manx 500
Since
1907 the Isle of Man, a tiny nation in the Irish Sea, has turned its public
roads into the world’s most storied race course. The “Manx” people, as native
citizens of the Isle are known, embrace motorcycles and racing as their
national identity – even printing images of racebikes on their coins. Their
beloved annual race is known as the Tourist Trophy, or TT, and no other bike
could be more emblematic of this event than the machine named for the island’s
people: The “Manx” Norton.
Built
from 1947 to 1962, the Manx is a marvel even today. Using only one piston kept
the bike light, a scant 313 pounds (by comparison, today’s “replica-racer”
sportbikes range from 350-375 lbs). Yet this single combustion chamber could propel
the bike to over 130mph. The Manx was the dominant competitor of the TT’s 264-mile racecourse.
The
Manx featured here is owned by Portland motorcycle icon Tom Young. In over 40 years of experience on two
wheels, Tom has ridden street, dirt, trials, ISDT in Scotland, Baja Desert,
Club TT, Supermoto, Central America, South America, motocross, choppers, sand
bikes, road racers, endurance race, cross country, desert race, dualsport,
vintage MX, vintage trials, and Alaska with a sidecar. Yet of all these
experiences and bikes, Tom reports that the first time he heard the Manx
start: “It was Beyond ear-splitting!”
Noteworthy
features of Tom’s Manx are its ‘Garden Gate’ frame (predecessor to the
Featherbed frame), exposed valve springs and, especially, its magnesium front
hub and crankcase covers. Following WWII magnesium was in extremely short
supply in England. The government doled out precious little of it, and only to
vital industries. Evidently deemed
vital, the Norton motorcycle company was allocated just enough magnesium to
build its Manx motorcycles.
