    'Tankslapper Damper

    Picking your weight up off the seat if the bike wobbles violently or slides and catches also works to reduce the effect of your body mass being so high on the bike. This allows the bike to correct and stabilize itself much easier. The less of a "whipping back and forth" mass you become, the quicker the bike will stabilize'

    +1 I found this with the Scorpio, I try to constantly put about 10-20% of my weight on my legs when riding, makers the bike so much easier to control, more stable etc. Its a light bike. My legs are so much better for it.

    Yeah mate .. when you're in a sweeper at 110klicks and the bars suddenly go full lock left to full lock right .. there's not much time to react .. you just know it's going to hurt ... and it did !!! (But I walked away ...)

    If only my tankslapper was a simple as this

    Banditbandit, mine seemed to go on for ever, I actually thought I had it under control as it became much slower and more stable-so much relief - relaxed on the bars (not sure about the throttle, I was trying to keep it steady)

    but it may have all started with a weight transfer on a corner with almost no traction-cold wet tar bleed.
    Over it now, I know what to look for on the road and what I think is what to do.

    there is lots of video on google on tankslapping.

    this thread reminds me that I should reread it again.

    I've owned and still have a couple of the bikes in the video.
    Only time I have experienced anything like in the video was riding from Split to Dubrovnik in 1989 on my freshly restored BMW R75/5. Two up with panniers and....a top box mounted behind the rear axle and it went into a severe wobble. I found the tyre pressures were too low.

    I can't say that I have ever noticed it on the R90s or the Norton Commando.

    My Racebike BMW R90 is good for 200+ over the hill at Hampton Downs and the only time it shook its head was the slight bump coming up the hill.
    I've since replaced the old steering damper and its barely noticeable now.
    It also runs ohlins on the rear and RT tweeked front end plus race tyres.
    At over 90KG's I think I know why
    Back in the day I didn't know anywhere near as much about suspension/tyres/riding methods as I do now.
    DeMyer's Laws - an argument that consists primarily of rambling quotes isn't worth bothering with.
