Likwid Posted June 3, 2009 Report Share Posted June 3, 2009 *generic asinine joke about being on one's knees*Good now that that's out of the way, it's amazing to see the gyroscopic power for a motorcycle... I know as a new rider understanding that the bike WANTS to stay upright is not easy... seeing this helps... although I wouldn't be able to save it Quote Link to comment Share on other sites More sharing options...

nochknstrps Posted June 3, 2009 Report Share Posted June 3, 2009 thats one hell of a save. I'd say thats more of highside in the making than a tank slapper, but the kid stuck it out. Quote Link to comment Share on other sites More sharing options...
krzwhtman Posted June 3, 2009 Report Share Posted June 3, 2009 steering broke loose on front , tank slap ... could have resulted in high side. since it was in the turn.highsides usually caused by rear breaking and catching at bad angle.

that dude Posted June 3, 2009 Report Share Posted June 3, 2009 what exactly causes a tank slapper? Quote Link to comment Share on other sites More sharing options...
Likwid Posted June 3, 2009 Report Share Posted June 3, 2009 what exactly causes a tank slapper?http://en.wikipedia.org/wiki/Speed_wobbleSustained oscillation has two necessary components: An underdamped second order or higher system and a positive feedback mechanism. An example of an underdamped second order system is a spring and mass system where the mass can bob up and down (oscillate) when hanging from a spring.We need a fucking engineer to interpret that shit.... *cough* Quote Link to comment Share on other sites More sharing options...

krzwhtman Posted June 3, 2009 Report Share Posted June 3, 2009 tom many to list so i copied and pasted from http://www.slash5.net/org/Tank%20Slapper.htmlSome causes and or contributing factors (sometimes a combinations of these),but by no means all of them:*Out-of-spec bearings (wheel, steering head, swing arm, ...)--bearings too loose--worn bearings--improperly shimmed--spun outer race--improper alignment (deficiencies in the rear of the bike CAN be telegraphedto the front)-- etc. ...*Out-of-spec wheels/tires--out of true--out of round--improperly balanced--improperly seated/inflated--unusual wear pattern-- etc. ...*Poor suspension--improperly adjusted--overloaded--worn/defective components-- etc. ...*Improperly loaded bike--too much weight on the back and not enough on the front tire-- etc. ...*Bad steering dampener ...*Wind turbulence (fast wind and or highway speed)--handlebar mounted windshield, jacket or anything else the wind can catch--exposed pillion back rest--saddle bags, especially wide ones on naked bikes--mis-aligned or damaged fairing-- etc. ...*Frame flex--any change in the bike's geometry that induces an undesirable effect ...*Road grooves--any road characteristic that induces bike instability (not to be confusedwith a bike's natural tendency to follow a groove or path of most traction)-- etc. ...*Anything else that can lead to or build on a harmonic oscillation affectingthe bike's steering which can also be a permutation and or combination offactors that add up to a wobble...http://en.wikipedia.org/wiki/Tank_slap Quote Link to comment Share on other sites More sharing options...
