Dirt bikes come up "On the Pipe" w/o notice. They go from comfortable acceleration to "OHH Mu Gawd!" & when they do, its in the blink of an eye. Dirt tires arent safe on asphalt, either, so, an experienced rider, who isnt experienced on THAT model dirt bike & onasphalt is a disaster waiting to happen. Sounds like it didnt wait long. Disaster is often impatient.

All that said, people with experience on dirt bikes tend to not fall as much on street bikes. Your bicycle experience, IF youve ridden hard in turns & felt it slide & had to adjust your body position to save it, then youre already ahead. But, if you have a friend w/ a dirt bike & you can get some seat time & play a little "on the edge" in corners, youll learn how to shift your butt from side to side, working core muscles, & what to do with the handlebars. Ive felt mine slip in an intersection, you know, that kinda "No mans land" spot out in the middle of a big intersection,, Thats a great place to slip down on sand or pick up something for a flat,, I learned to not go thru those areas, right then, but the dirt bike experience kicked in. My butt shifted right, I turned right a hair, shoved down on the right peg & eased back enough on the gas so I wasnt accelerating, but wasnt slowing enough to make it want to throw me off to the right. Its not stuff ya have time to think about. Its gotta be reflex.
