Would it be worth spending money on a honda CRF150F?

I'm planning on buying a Honda crf150f (first ever bike, don't try to convince me otherwise, because my minds made up), and I'm planning on having it for about a year and then selling it after that year and buying a bigger bike. So would it be worth it if i buy something like a fmf/pro circuit t4 pipe/exhaust for it? (both cost around $350-$450 here) Will i feel a difference in power? And remember ill only be keeping the bike for around a year. And if i should buy the exhaust, any other recommendations would be great!

Best first Motorcyle for teenage girl 5'1?

I'm looking at getting my first motorcycle soon, preferably a sports, I don't like the look of cruisers so please don't suggest any to me. I'm 5'1, and 120 pounds. And live in a city with lots of wind and hills. I've been looking at a typical ninja 250, because i've wanted one since I was a kid, and found out that they're actually really good bikes for beginner riders. Or maybe a Honda CBR 250. I'll mainly be using it for commuting to work everyday which is about 20 minutes away and around the city. Also when I gain my confidence i'd like to take small roadtrips on the freeway. Which bikes are suitable for me?

Added (1). Btw, i'm turning 18 y/o in a month.

I'm honor to be a part of your family?

Actually I bought HONDA TWISTER 110 cc in 2011. Recently I'm shifted to Delhi for my profession, and it happen very quickly. For that I'm not able to carry my bike to Delhi.
I'm eager to know that there are any option which help me to receive my bike in Delhi.

Should I upgrade from a Honda CBR500r to a CBR650f or Ninja 1000?

I'll try to be quick. I took the MSF class before having ever ridden any bike. I ended up getting a CBR250r. I upgraded to a CBR500r 2 months later for a couple of reasons.

1. Just felt under powered… Especially on the interstate.

2. The vibrations were so annoying after 45 minute trips.

So I'm currently riding my CBR500r and have been riding for about a year. I've come across an opportunity where i can upgrade. I've had my eyes set on the CBR650f because I want to maintain the same upright riding position. I do NOT want a 600 for that reason alone. I just don't care for the positio.

Then i sat on a Ninja 1000 and was surprised at the feel(only sat on it). It felt light and the handlebars are great for me.

So my question is would jumping from a 500 to a 1000 be extreme? I've read mixed reviews on the 650f. Some say it's a nice bike, but lacks personality. It's boring. I'm torn. I'm sure the 650f will suit me immediately for a while. However, I don't want to have wished I gotten the Ninja 1000… After a few months. Opinions please ;-)

Can I ride right after the MSF course?

I want to buy a Honda CMX250 but I don't have an suv or pickup truck to haul it in. So would I be able to learn how to ride it home after my MSF course? It's a 2 day course from 9-5.

Added (1). Oh and I already have experience riding in the streets with my 50cc scooter. I will not be taking any highways either since it's only 15 minutes away
