I am looking into getting some track plastics for my bike. I pretty much have a front/upper & a tail that uses the stock seat (haven't paid for them yet). I see some track pictures on here that pretty much have nothing on the front of their bikes as if they just took off the whole front fairing/headlight assembly and left it naked. Can I just do that or should I replace it with an upper due to the wind and it not feeling choppy?? Also a stupid question, if I have an upper do I HAVE to have a lower or can the upper be mounted on it's own? I don't want to spend money on an unnecessary lower. I am not a newbie to trackdays but I do like to have fun out there and just ride in novice. I don't "race" or need all the bells & whistles of a full race bike.
