This is primarily a consequence of racing "back in the day", Italian fit was the go to default for a long time and much that followed as the monkey was efen the futbol to get the aggressive position that most wanted to emulate whether they actually raced or not.

Many fit systems catered to this and made it even harder to get comfortable on the bike for touring, joy riding, commuting, etc.

I never raced or cared and would never have been able to get serious the way I'm built and my lakadaiscal attitude about racing bikes.

Drag racing MC's is a whole different story however.
