In 1950, Norton introduced the now-legendary Featherbed frame, which quickly earned a reputation as the best handling chassis money could buy. 

Before long, builders had began to create specials that combined the best engine with the best frame, resulting in machines like the Triton (Triumph-Norton), Norbsa (Norton-BSA), and Tribsa (Triumph-BSA). 

In general, a Triton is a combination of a hearty Triumph twin engine and a sweet-steering Norton featherbed frame

One of the rarest, most legendary of such fusions was the Norvin, which involved shoehorning a mighty 998cc Vincent V-twin engine in a Norton frame.

 The originator of the combination was no less notable: “It’s widely acknowledged that the first Norvin was the brainchild of the legend that is John Surtees.” —Timeless 2 Wheels
