Upgrading a disposable motorcycle is a waste of time. You don't need to buy a new 125cc bike, get one that is 2-3 years old and well maintained for less then half the original price. A 125cc bike will not be good for driving on the street unless you like in a rural area without highways. The age limit to drive depends on your state, I don't know Indiana's. You definitely will/should take a class to learn the laws of the street before riding in traffic. If the 125 you are looking to buy is a 2-stroke you need to work on your mechanical skills as the engines don't last that long.

I ride a 175 for about 3 years when i was in high school. Beat the hell out that old bike. I pay $200 for it and got my $$$$ out of it.

Take new one

If it is just a trail bike then I wouldn't recommend it. If it is a motocross bike not a problem. The transmissions in MX bikes have better synchronizers and are meant to be shifted without a clutch. I was taught in motocross school not to use the clutch except off the start and up steep hills where you don't want to drop any rpm's. I've been racing MX, flat track and cross country since the 70's and never had a single transmission problem.

Based on your size, age, and skill level, I would recommend you start out with either a 100 or 125. These bikes will be shorter and easier for you to ride than the bigger bikes, say 225 or larger. You also don't need that much power for riding in the woods……….save that for a track later when you gain more experience. As far as brands, the kawasaki's and honda's are almost bulletproof reliable. Remember, you can always buy/trade for a bigger bike later. Get the smaller bike and take a dirtbike class, you'll be glad you did! Go to MSF.com (motorcycle safety foundation), they have a listing of a school near you. Good luck!

I'd tried to make a 'bike' version of a site I saw online, called 'cardomain.com' It's a pretty kewl concept, people get profile type places, to post pics of their rides (custom, and stock). But when I got outta school, I didn't have Dreamweaver, and my HTML sucks, so it never went any further… Good luck tho!
