    I've learned to keep both hands on the bars at all speeds on my 84 GS1150. I've heard criticism of my other ride a 79CBX for sketchy handling and it was somewhat true, but nothing like I've had on my GSX.

    That's kinda why I keep this GS. After having a late model bike and feeling the difference, riding the GS is a walk on the wild side.

    Which reminds me, I used to have a ZX1400. Had it toured out too. Really nice Givi side bags and a trunk. Biggest I could find to mount on it. In hindsight I don't know why I didn't just get a concours. Anyway, one day on my way to work I got on an entrance to the highway I had taken a thousand times. It was a big circle. I had been incrementally taking it faster and faster every day. All of a sudden one day right at the exit of the circle onto the highway the bike bucked me off. I was doing about 55 and somersaulted for about fifty yards down the onramp while the bike slid on it's side into the middle of the two lanes. I managed to get up and pick up the bike and get it to the cement barrier in the very middle and that's when I realized my wrist was broken. That accident screwed my back for the rest of life. I was very lucky I didn't land infront of someone comming around the corner. I still don't understand why the bike suddenly tank slapped and bucked me up in the air. It was one of two things; 1. I hit a stone I didn't see because it felt like the bike hopped into the lean, or 2. all that luggage had upset the balance of the bike and the way I took that turn was the limit it could keep it's composure before showing me I was stupid.

    Sounds like you highsided. As you exited the circle you were probably accelerating while still leaned over and lost rear end traction, until it caught again and threw you off. Could have hit a small oil/anti-freeze or water patch, maybe your tires weren't as warm as on previous days, etc. Can happen for many reasons, been there done that.

    Huh, I've generally experienced my 550's as quite stable; and I've pushed them up to 180km/h (111mph). And it must be said, I've discovered serious repairs on one of them (welds on triple tree; welds on the frame).

    That being said; I had some icky situations with all of my bikes; but it always came down on suspension issues or worn tires.

    Oh, you're referring to an L...less preload on rear...eh, maybe this reduced front downforce just enough to make it iffy

    That's what I'm thinking. With the big Givi topcase on the back and the no preload, could be it was on the verge of lifting the front wheel.
