          Since fall is here & street riding is getting fewer & farther between potential rides, I watched the "Unrideables" part 1-2 again...,

          Good stuff all around...even Wayne mentioning the unforeseen dangers inherent in racing at that level & accepting the consequences.

            Yeah, crazy stuff. Glad I don't have to ride a 500cc 2 stroke on track days. They wouldn't have amateur track days if the bikes were that wild today.
            PS: I like Schwantz mo-betta, he's got a sense of humor.

              You'd be counting highsides all day.

              The intestinal fortitude required to ride a 500 cc 2-stroke tuned to the limit with no traction control, ABS or any other rider aids is incredible. As we saw in this video, even the best riders in the world were launched into orbit with just a hair too much pressure on the throttle.

                What causes the High Side? Is it rear wheel spin then grab? Or does it has something to do with the wheel base and steering geometry? I watched the video and noticed all the High side crashes. Just curious.

                  Rear tire spins up, steps out of line with the front tire, then grabs, launching the rider off the bike. Usually it's caused by the rider being a little too ambitious with the throttle.

                    Right, wheel spin then grab. Happened to me at just 20 MPH, result was broken right clavicle.
                    Why those bikes of that period kept high siding was, those 2 stroke Grand Prix engines had a very sudden power surge at certain RPM, like a rocket boost.
                    Rounding a corner in a race their bikes hit that RPM power surge REAL HARD.

                      The best riding season is just starting here. I love these videos! Reminds me of the days when I actively followed Lawson, Schwantz, et al.

                        Okay, so what causes the Low Slide? Would that be the front wheel loosing traction? When I was at the Moto America race this year, there were two crashes that I saw. Both it seemed like the whole motorcycle just washed out. Loosing traction both front and rear wheels. The racer just scooted on his backside not getting hurt. I suppose the modern race motorcycle is equipped with traction control and all that jazz...?

                          A low side can be either the front or the rear going.

                            I believe the main factor of the the "highside" is the suspension loading up after a slide, when the tire decides to grip again, causing a massive moment of compression-bottoming of the suspension, then release, adding to the height of departure from the bike.

                              Usually it's the fault of the rider, leaning the bike over beyond the limit of the tire grip.
                              It's very common type crash on track days, newbee riders trying too hard before they learn their tires limit. Mostly none or slight injuries, bikes skuffed and some bent parts.
                              Can happen on a bicycle, taking a corner with sand on the pavement.
