^ Funny, I have the perfect example to illustrate that today. I bought my friend her first bike at the weekend and delivered it to her. Today, on her second time out, she hit a gravel patch and fell off. Now that's just a combination of bad luck and lack of experience that could happen to any starter biker, but both she and the bike are fairly unscathed because she was on a small, relatively light & low powered bike.
Now, if that had been a 750, not only would the accident have been more likely to happen in the first place, but I'd bet we'd be talking injury, and some expensive repairs too.
