Could be any of loads of things; an unbalanced front wheel, a slow puncture at the front, a badly fitted tyre, knackered steering head or wheel bearings. He's going to regret not wearing leathers though, as he's missing several layers of skin now. It started as he accelerated, so the weight coming off the front end created the tank-slapper.
added throttle the front got light and he suffered tank slap, he could have shut down throttle rather than try to power through it, he would have felt the front start to lift up light . No Gear = No Idea and a ton of roadrash and sleepless nights
Watch the very start again. Driving one handed. Left hand comes up to the bars after he hits a little bump.
aye missed that, not being in full control and able to hold the bike as it dinked a bump, then it started a tankslapper and the rest is roadrash and the wish he had geared up more lol.
if you have both hands on bars and you come into a tankslap , what is best to do is trail off speed, close off throttle gentley and pull in clutch to cut power to drive train then feather the rear brake very lightly . its hard to say unless your the rider, sometimes you can power oit of it but you gotta have the power to do that and the balls of steel, but its 9-10 times chopping the throttle slowly disengaging the drive via clutch and feathering rear brake to shave speed off, tankslaps tend to come from non control or more so to high speed aka speed wobbles. Scooter wise : slowly feather out the throttle and bring in a tiny bit of rear brake to help shave speed off, the shutting down of throttle will start engine braking as the motor still powers the clutch while its got force that shaves speed down, the feather action on the rear brake does the same. scooters lack the raw power a bike can have so its neigh impossible to power through the tankslap/speed wobble
