Unfortunately I had to notice that the racer was 600 obviously damaged in transit. Amazon has responded quickly and leave the damaged equipment to pick up. In addition to Amazon I had complained even at the distribution company to the apparently "poor transport". It there had understanding for my request and you thanked very friendly for this information. Now I have set up the new Racer (which was smooth and easy) and have already driven some "kilometers". It's great fun, especially as the computer is working properly and everything is easy to read. In addition, "runs" the Racer 600 pleasantly quiet. I'm very pleased, especially since the unit also looks chic. For those interested, I can only recommend the Racer 600.
