Heh... that's ok.
I'm 135 lbs, so the 250 is really good for my weight. But like I said before, use this time in your life to try EVERYTHING. Cruisers aren't my style either - but then again, I'm too junior to know "my style". Low displacement is turning out to be "my style" because my ZX12R is just too goddam much bike, and I've damaged it. My 250 I came close to dropping several times, but I was able to get it in the nick of time, thus saving the day. Now that I've experienced a few drop situations (And 2 drops) I've gained the experience necessary to handle something a little heavier - at least until I drop that.
Drops happen due to inexperience, but I've seen 40 year old veterans drop some serious steel as well. As you get better and better at riding, you'll come to perfect stops and handlebar movements.
The 250 may just get to be too little for you within the season. If that's the case, make sure you have appropriate financing and costs to get out of the loan. The 250 is again nice because it's initial purchase price is so low, and when you need to get out of a loan - even if you take a hit, it'll be a low hit. And that translates to dollars per day that you'll actually spend on riding.
When I got my cheap 250 I was using it for daily riding to work. If you choose not to do that, then you'll need to get all of that money-per-mile value on the weekends. If you do that, then the 250 may "last" you longer.
Also, you may want to look at the GS500 Suzuki. The only reason I didn't like it was because of the triple-mounted gauges and the fit of the plastics. Other than that, it's a great bike, both in looks and performance.
If you choose to this route, try to keep the bike new as possible. I've owned plenty of older bikes and their maintanence made the experience ... "not so good". When I got the 250 it was about the same speed as my Honda 500 Shadow that it replaced - but even better than that, it ran every goddam day. Which gave me the experience necessary to become a "motorcyclist".
