Considering the Aprilia 457: Thoughts and Comparisons

Lately, I've been looking at bikes and I fell in love with the ZX10R, but I can't afford it currently. So, I've been considering the Aprilia 457, and it looks pretty good. I'm a complete newbie, so I have no idea about the features and specs. All I know is that it's a 457cc bike, so I assume it's pretty fast. The hardest part is convincing my parents to get it for me, but hopefully, I'll figure something out.

Other than that, is the bike actually good? Everyone says it's a segment killer, but how exactly? A GT650 costs around 3 lakhs, so shouldn't it be a segment killer instead, considering that it has 650cc vs 457cc? I get the weight-to-power ratio, but the GT has 200cc more—shouldn't it be faster than the Aprilia? I apologize for this, I'm still a newbie. I've never owned any bikes, but I've had my fair share of bike rides. Does it make sense practically to own a bike? I already have two cars and an Activa.

On a side note, I have an XUV700, and the power on that thing is phenomenal. The pickup is amazing, and the 2000cc engine makes me smile to this day when I push the gas. I've driven it for 40,000 km. My question is: hypothetically, if I get the 457, will it give me a similar feeling to the one I get from the XUV? Will I get that same kick and smile? And if I race both of them, which one is going to win—the 2000cc car or the 457cc motorcycle?
