Welcome to the forum!
Have you considered basketball instead?
Kidding aside, heres what I can tell you that I know about the R3:
Its plenty powerful for the highway. I have videos of me riding it in San Diego traffic, which averages 75-85 mph. Bike has no problems. A fair argument is that I weigh around 155-160 with gear and back pack on. A few others here will attest to it being capable in traffic, so wait for them to chime in and give you their rider weights. A few of us from California have stated its fine in traffic. I stress the California part because people in Cali typically ride/drive pretty fast.
I moved from a ZX6R to the R3 and will admit at first I didnt like it. I can honestly say now its been my favorite bike so far. Sure I miss some traits of my other bike, but as the saying goes, there is no perfect bike.
The bike is an absolute blast in the twisties, and even more on the race track. Very fun bike. Very light as easy to ride. If you arent interested in all of that just yet, then here are other selling points: Its light, fuel injected, cheap to insure, very manageable for a beginner, parts are cheap, good on gas if you dont ride it like its a race bike (to each their own, I have never gotten very good MPG on mine cause I ride different than the guys trying to max out on fuel), easy to work on, has good aftermarket for a bike only a few years old, its comfy and I am sure there are a few more things I could write but cant think of right now.
Will you get bored of the bike? Sure, if you never want to learn to ride a bike past commuting to and from work and only care about going fast in a relatively straight line. If you enjoy twisty roads or the track, you will do the opposite. You may just have more fun on the R3 than a 600/1000 that all your friends are trying to pressure you into buying. Speaking of which, ask them to watch the video at the end of this reply and see if they are bored doing things like that on their bike. I just feel there are far too many people on 600/1000cc bikes who are too concerned about being on a small bike, thinking people will mock them for being on small bike, yet they cant ride their bike very well through a nice twisty mountain road or the track.
Alot of us here have moved from bigger bikes to the R3. It really is a blast to ride. You are going to want to buy a different bike eventually. It happens. I am willing to bet after owning several bikes, you will look back and say something like "man that little R3 was alot of fun".
Enough ranting from me. Enjoy this video. Dont forget to ask your friends! If they do that kind of stuff on the track, ask if they recommend you learn that kind of riding with a bigger bike or smaller one.
