Telling a rider how to ride to avoid a tankslapper by riding a certain way is just silly. Getting out of it, yes, there are steps to take to stop the insanity.

A tankslapper is a harmonic vibration of the bike / suspension / tires that builds on itself until a change is made or the bike goes out of control. Rider input has nothing to do with it, up to the point the rider could drastically change throttle / brake / body position to attempt to control it. Not very likely they will be able to tho.

Steering dampers for the win. And proper tire pressures and sizes. And suspension set up by someone knowledgeable...not redone or anything, just properly set up by a suspension guy using factory available settings trackside.

Saying the rider did something only makes everyone nervous that their riding style will bring on a tankslapper. This is just not the case. It is a bike harmonics issue.
On my SV when i had mine.. it was a combo of light front end under acceleration, stiff frame on SV, bump and stiffer carcass on slicks that essentially created the harmonics mentioned above... I then stayed light on the handlebars... and rode it for 200 yards trying to regain control... still ended in being thrown.

If I can't eat it, race it or sleep with it then whats the point?

Motorcycles are like women... once you ride one... you wanna ride em all.

Just watching those two short clips gave me chills about the boneheaded riding I just witnessed. Like the white leathers and blue wheel bike hitting the brakes in an acceleration zone after T2. Coulda been ugly.
What? Track days aren't safe so go do a track day? What proof do you have to back up that racing is safer than track days? I see a lot more people go to the hospital on race day than I do during track days.

Ummm, yes, there is. Bar input has a lot to do with tank slappers.

Also trying to stop that little wiggle when you set a wheelie down not quite straight or when the front end is light transfers the normal righting motion of the front wheel through the rider into the frame and amplifies the problem. I suck at riding in general but Dean with Ridesmart noticed that I often get a bit of a wheelie while still leaned over coming out of the gut check at MSRH,which always freaked me out. He told me to concentrate on keeping my arms loose and to think of them as part of the suspension, "the forks of my upper body" worked like a charm. That and a good steering damper.
