Confusing crash carnage

    Hey Mike, where on the track was the bike retrieved from?

    Is there a chance the recovery truck yanked the bike from the back wheel?

    Single bike crash.

    Just off the racing surface. Racer crashed with the bike and was right near it and rode the crash truck back with the bike.

    TWF2 2 heads are better than 1

    Seen that before, had crashed bike with dog bones bent. On this one both were bent to same side.
    Also seen couple shocks break/separate where clevis screws in.

    Wow. Odd for sure. Im curious as to the outcome.

    I've seen shocks torn apart, compressed to death and linkages bent along with the swinger. Never seen this, though.

    Outcome is we'll fix it but I'll be tortured forever not knowing how it happened.

    Well,Im really curious as to solving it so much that it hasnt effected another aspect of the bike that we cant think of at the moment if that makes sense.

    Still have to wonder if anything else is tweaked. You would think the swingarm wouldn't come out of that in perfect shape but who knows

    Still had throttle open when back wheel came off the ground then stopped quickly when making contact with the ground during the slide. Could the sudden stopping of the wheels rotational force have enough inertia to do that?

    Yep, like I said, seen it before. But never without flipping. I guess it could have slip into something and got hit on the (top) side of the wheel to puish it that direction.

    So what prevented it from extending further, and bending them more? And no internal damage to shock topping out hard enough to bend the dogbones?

    I think you should get the factory involved.

    Steel is a wonderful material...in tension. In compression, when it buckles by going into plastic deformation, exceeding its yield strength, it offers little additional resistance. All that force has to go somewhere. What are the chances that it doesn't do additional damage?

    Not enough for me to put money on that at the craps table.

    With 90% of bikes encrusted with cameras these days you'd thing there'd be multiple angles of 4k video available to solve this mystery.

    Oh yeah...
    "forgot to turn it on"
    "haven't got the aim dialed in yet- got 2 hours of my foot"
    "used it once then realized nobody wants to look at my shitty unedited raw footage and editing is hard"
    "just put them on to look cool"

    This just popped into my head: was the bike possibly previously crashed, slightly bending the links? They'd be much weaker had they been previously damaged.

    Rear wheel hit something just hard enough to fully compress the shock, rear went airborne some amount with the suspension fully compressed and the inertia of the rear wheel moving toward the extended position was enough to compress the links when the shock fully extended? This only works if there was little or no damping from the shock in the extending direction, otherwise it would slow the travel of the wheel and reduce the inertia.

    Have you sent pics the Kawasaki to see what they think? Their needs may be interested in odd damage like that.
