You should probably direct this question to someone who has a lot of experience racing competitively. I don't think most of us have pushed our bikes beyond the limit often enough to determine if there is any warning the tires are going to let go. It's kind of like asking if you can hear the bullet before it takes your head off. FWIW I hear a different sound from my tires when I am cornering aggressively than straight up riding or casual cornering. It's a good sound. Sometimes I swear I can feel the tires biting into the pavement. It is also a good feeling. I suppose the sound from my tires would change if they lost traction, but I am not about to find out for sure. You first ok. ;-)

I expect speed is a factor... just about any bike can scrape bits at parking lot speeds. As speed goes up, the bike has more energy (mass * velocity) and at some point the tires can't hold on. What point that is, depends on a lot of things. For example, I've watched videos of sportbikes scraping hero blobs @ 45MPH, but that doesn't really apply to your cruiser. > b)If it happens, how does it happen?

The front end can wash out just as easily as the back, if you touch the brakes or even just roll off the throttle which transfers weight to the front. I have never lowsided, but I did feel the back end get squirrely once when leaned hard over at the very end of a decreasing radius turn. Kind of a vague wandery feeling. So I did get a LITTLE bit of warning, but it wasn't real obvious. I prefer stay away from the warning point from now on since it would be easy to miss.

Go to the nearest roundabout and play all day. There is no substitute for practice. :)
