These bikes are pretty straight-forwars from my experience, and from what i have read here. My 2009 1125R was stock for six days after i bought it (second owner) until i bought a jardine rt5 carbon slip on. Since it still has the stock ecm, it throws a check engine light every once and a while, but the stock ecm will do that to you. I would highly recommend an eric buell racing ecm if u plan on getting exhaust. The stock ecm can handle a drop in filter, but thats about it. Unless u are going to stay stock, whe ebr ecm is ghe way to go. I am going to order mine im a week or two, but the 5k mile service and new set of tires are badly needed. Enjoy that bike! I love mine. Sometimes i kick myself for not getting an xb12s, but everytime i open it up, i am reminded of exactly what kind of monster i am sitting on. I would say get a slip-on, a k&n filter, and an ebr race ecm and call it done! Ride safe brother, and own the entire roadway!
