That was exactly it. I found it rumbly at first when I sat on it, but later on not so much. I guess I got used to it. Are all bikes rumbly? Or are newer bikes smoother?
Why do people seem to be against electronics for a first bike? Is it wrong that I prefer to ride a bike that will let me know when my brakes would've locked up if not for ABS? I can still understand I've gone over my limits when ABS triggers, no?
I can understand how traction control might be doing more for me, but isn't it safer?
By rumbly do you mean it vibrates? That's just the bike. It's a single cylinder, 200cc motorcycle. You probably never went above 2nd/3rd gear at 20mph max. So you were probably high in the RPM range.
People mainly don't like electronics for specific reasons. Usually their claims are extra weight, more expensive motorcycle and more things to go wrong. While all of this is true, it doesn't or (shouldn't) apply to real world driving. You should choose exactly what you want from your bike. You can do without ABS or traction control, but just make sure that you ride accordingly.
All electronics do help you in real world driving. Usually, when people are against it they have their own opinions, or they're using their motorcycles for track days. Some people like to wheelie, etc.
