First bike? Yeah. Get a sportbike so when you drop it in the driveway, you can spend thousands making it pretty again. Or crash it doing 150. Alot of us have both. And various other motorcycles, but man, what answer did you expect? Get on a sportbike forum and ask them. See how many of them tell you to go moto.
My opinion may be biased, but I just got my first motorcycle about 2 months ago and I took my Motorcycle Safety Course at the Week-End and I will honestly say that me buying a motard is my best investment. I radiator shroud costs a bit less than chromed up gas tank. It really made me handle and ride slower and it is really a beginner friendly kinda bike. After you get the hang of it just upgrade to a Husquavarna, KTM, etc..
Think about it and try one. :thumbup:
Having been a regular attendee/participant at a lot of the track days and races in my area, the guys with a dirt/MX background always seem to have the upper hand when it comes to handling a street bike. There are a lot of things that an off road bike will teach you about bike control that you just won't get on a street bike (sport bike). I would think that this decision is a no brainer. Of all the bikes that I have and have had the sumo is the one that stands out as the most fun and versatile by far. Sportbikes are fun, but I would highly recommend getting some seat time in on a sumo and then looking into a sportbike later on down the road if you still have the urge.
based on your name, i'm going to assume you are in fact a woman. That said, if this is your first go round, a sumo like a DRZ wouldn't be a bad choice if you are like over 5'8'ish.
sport bikes are one trick ponies, but still fun, lots of fun. I just find the sumo way more useful at the moment. try them both!!!!
