Need some direction for next bike.

1) Your physical size (both height and weight are important) 5’8” 155lbs
2) How physical / aggressive are you? I’m pretty much invincible ;) and play hockey.
3) What do you plan to ride- MX/SX tracks, woods, fields with friends?? Trails and pits with friends.
4) Do you have any riding experience? Rode a 125 four stroke for a year.
5) Do you think you will race? No
6) Are you mechanically inclined and will you be doing your own bike work? I can do all my own work.
7) Do YOU have a preferance to a brand/ motor choice (2 or 4 stroke)? Wonder if I should get a 125 2stroke or 250 4 stroke. Like Yamaha’s and Honda
8) Do you have a dealer close by your home that you might use and what brand(s) does he carry? Yamaha and Honda
9) How much do you plan to spend on a bike? Roughly 2500-4000 Canadian.
10) Do you live in California? No
11) Want a bike that is newer. At least 1999 or newer. I also was wondering how much difference there would be for me between a 250 or 450 four stroke trail bike.

I found a bike that is a 1995 yz125 and it is older than I wanted but it is listed for 1500CDN. My friend rides a 1997 cr125 and that bike is fine. If a 1995 is good then I would go that old to save some more money. Soon I'm gonna have to buy a truck when I can drive with my N so I'm thinking about that a little bit to.
