Common error that about the badging of a bike
The Triumph Daytona T595 was introduced in 1997 in an attempt by Triumph to tap into the sports bike market. Despite the T595 name, the bike featured a 955 cc displacement in-line three-cylinder engine designed in part by Lotus. Along with the other triple-cylinder Triumphs, the Daytona helped to establish the newly-managed manufacturer and its distinctive and unique three-cylinder motorcycles.

In 1999 the bike was renamed 955i because the T595 model name gave the impression that the bike's engine displaced 595 cc.
