    Possibly due to too little rear damping... surprising how much the rear is pumping. I wonder how often tank slappers are accompanied by a pumping at the rear?

    At 0:56 - is that poo I can see? :)

    What normally causes tank slappers? I thought it was just some resonance frequency of the chassis kick-started by a front wheel skip. I guess what's more important is how they correct themselves.

    Think it started at the back. The front facing camera seems to be bobbing up & down before the front suddenly goes nuts. Tallies with my experience on the R1, where some brands of rear tyre would combine with Yamaha's shitty loose linkages to throw the bike into a slapper.

    Fuck yeah, I got that on camera!

    Hope he tested the front brake after that before he really needed it.

    It's just possible it was hitting the dirt that saved him... reduced traction didn't rip the wheel side to side so hard and gave him a chance to hold it straight. But I haven't seen a rear wheel pump like that since Ben Spies at Qatar (oh yeah, that was a cracked seat, right...>jerkoff) Do you think his mates wound all the adjusters out while he was in the pub?

    Started at the back for me too.
    It's a supermoto no?
    I have wondered of Supermotos might be bad for it, with soft, long travel suspension, and huge steering lock ?
