Can anyone please explain to me the purpose or need to rev your bike all the way to the redline? When would you ever need that? I find changing gears at around 4k/5k to be enough, and I've gone all the way up to 100mph on sixth gear while still at 10k/11k, so why do it? Is it really just to be a badass, or is there some sort or scenario where that many revs will give you better performance? Sorry for the noob question.
