Stamping that line in usually prevents failure because it allows a sharper bend. If you ever put thick aluminum in a bending jig you will see all the stress lines and mini fractures appear on the far side from stretching. This is a way to alleviate that. But not a great idea on something that...
The top third of the power band is now available unless you ignored the low rpm limit. I don't know if anything becomes unlocked in the mapping. I noticed nothing different but my other bike is a lot quicker so I didn't expect a lot from it.
