what should i do?

I own a kx250f, its a good bike but me and my brother both need something to ride over the summer. I have a job lined up so money isnt really a problem but i was thinking about getting an rm250 instead of a 450. Then, I could spend more money and gear and parts, and so on... Im 6'0, i weigh about 180 pounds, and im 16. Im kind of aggresive but im still learning, im more of a calculated rider... i do like the steady pull of a 4-stroke, but i recently drove a 2-stroke and i have to say, i liked the powerband :nod:

haha

Haha, alright, im going to test drive an 03 tomorrow... is there anything i should know about them if i do buy it

because my 18 year old brother needs something to ride to, we were both looking into racing

it will be mine, the 250f doesn't feel fast anymore... but i don't see this form

1) your physical size - 6 foot 180 pounds
2) How physical / aggressive are you - pretty aggressive
3) what do you plan to ride- MX/SX tracks
4) Do you have any riding experience? about a year on the kx and about a year on a ttr-125 :p
5) Do you think you will race ? yes
6) Are you mechanically inclined and will you be doing your own bike work? yeah, i dont know much of anything about the carb on my bike or any bike for that matter, at least not yet.
7) Do YOU have a preferance to a brand/ motor choice - i would prefer a suzuki 2 stroke but a kawi or honda 4 stroke
8) Do you have a dealer close by your home that you might use and what brand(s) does he carry? yes, yamaha, suzuki, and honda
9) How much ($) do you plan to spend on a bike? anywhere from $1,000-$3,500
10) Do you live in California? no
11) Your age? 16
12) anything else that you think would help form an opinion - i want something it will take me a while to "tame" or get used to its power, i already have a 250f, i dont want anything with a lower cc than that that is a 4 stroke, im also not interested in a 125 2 stroke.
