What do motorcycle friends mean by TT?

TT is the abbreviation of "tourisithrophy", which means motorcycle racing.

The most famous among many events is the "Isle of Man Tourist Trophy", which is hailed as the most dangerous street motorcycle race in the world.

It has a history of 112 years since the first competition was held in 1907, although it was suspended for several years due to World War I and World War II.

But such a passionate competition has not only never disappeared from this world, it even appeared earlier than famous motorcycle championships such as MotoGP and WSBK.
