The high-side comes from the bike stepping so far out sideways that the rotation of the tire is almost perpendicular to the direction of travel. At that point the tire will get enough traction, in the direction of travel, that it will pitch you off the side of the bike in said direction. The rider error is too much throttle input for the available traction. When traction is lost because of the overwhelming torque the RPMs climb until they are stopped by the rider of the limiter. If there is 5,000 RPMs available to rotate the engine will deliver it, and the bike will turn sideways until the tire stops accelerating. If there is only 2,000 RPMs remaining the sideways movement will be stopped much earlier, and will almost certainly prevent the high-side. The engine acceleration happens so fast you will not have time to react before it hits the limiter. Traction control can help prevent it because it checks tire speed once every 1/60th of a second. Human reaction times are 1-1.7 seconds. A high-side only takes .5-1 second to occur.
I suppose if it helps explain my particular experience...it was exactly as Truwrecks depicts here. When I took flight, I would say I probably entered the turn around 4,000-5,000K, probably on the brakes because at that low an RPM, I had no engine braking to setup for the turn...coasted in (loading the front end because I had been using the front brakes - although I try never to "ride" the brakes through the turn) and then nailed the throttle upon exit. The spin was instant...and violent. Completely spun sideways like I was the "Mission Impossible" stunt rider attempting a rolling 180. My fault...no doubt.
The only surprising factor for me was that it seemed to be the same way I had come off the turns before. By that I mean that I never really babied the throttle when I was really on it...I nailed it, and she freakin took it!
But...I was always wound up in the revs. Dragon's Tail is by far my favorite place to ride. For some reason the tight turns REALLY suit my natural "style" to ride hard. I had gotten very good at pulling these small wheelies coming out of the turns (certain ones) hard on the gas and the bike always responded well...it would start the lift just before straightening up, then pull just a little until I hit the limiter. I was always in 1rst gear and kept the bike wound up in the revs to use the engine braking for setting up entry and speed control through the turn. I found that I was hitting the limiter on exit too often between turns, changing gears up and down, so I dropped a tooth on the front sprocket so I could get into 2nd gear...best trip I had ever had - and the hardest riding I've done. My high-side was about two weeks later. It was on the same US-129, but a good bit south. We had just ridden Warwoman Rd and were on route to the next waypoint (I'm a follower cause I never know where we're going - but I've always been a #2 follower till we get where we're going
).
I've not attempted that type of riding since. Looking back, I believe I was at the breakpoint way too often and didnt realize thats what the feeling is like. Not trying to brag, but I never had anybody that could stay behind me to tell me what was going on (anyone in our group anyway - I will say I had a pair of R1's come around me like I was a frickin chopper!
).
Until you wreck, I don't think you can appreciate how close you have come to wrecking
.
I am definitely going to start some track riding...budget is a constraint but I hope to learn some things and get my confidence back to where it was.
Having ridden the way I was and being a little skiddish of pushing that hard again, I hafta say I don't enjoy the ride as much as I did back then.
