Why- whenever you unload the front end (by us sueually wheelies) and the steering gets crossed up, as said above. This also happens all the time at tracks or twisty roads when you accararate at the apex and your front end lightens because as you come out of the corner your front suspension unloads combined with the accelaration lifts the fron and essentially wheelies out of the turn you can cause a major tank slapper too. In fact useually worse.

Why they are a hazard- the front end wobble is actually never dangerous what is, is your reaction to it. See, your motorcycle will automatically correct a tank slapper without any help at all even severe ones. The back tire remains constant so when the front wants to dance around on you the driving wheel will push it straight, the next time your at the grocery store watch peoples shopping carts, without a doubt you will see one with a wobbly front wheel, the reasone for the wobbly wheel is because it's higher than the rest of the wheels so as it skims the ground it thrashes from side to side, exactly what happens when you set a wheely down with the bars slightly crossed up.
So what causes the crash. very simple it's a matter of force transfered or conducted. When you have a tank slapper your automatic response will be to "GET CONTROL OF THE MOTORCYCLE RIGHT NOW" so what you'll do is vice down on the bars when you do that you become a conductor and that front end wobble is transferred through your rigid body directly to the rear tire. Once that happens now you have two wheels out of control and the driving wheel is now unable to push the front one straight resulting in either a crash or a rider with soiled pants.
There are two ways to correct this, and I highly recomend both of them used together.
One as said above a steering damper, I personally recomend the scotts but there are a lot out there to choose from just make sure you ask around because you don't want to cheap out when it comes to this item. A steering damper is simply a buffer that "kills front end wobble" useually by use of a hydrolic fluid so when the bars suddenly ossilate the damper tightens up and nutralizes the wobble without transferring it to the rest of the bike.

Two- be consious or this and practice becoming a better rider. A really good way to practice what to do in that situation without endangering yourself is find a grooved road that is under construction. Most riders hate grooved roads because it causes an uneasy drifting sensation. it is almost exactly like a mini tank slapper. Notice the differance (it will be slight but you should feel it) when your on a grooved road and you ride really stiff with your arms viced onto the bars and when you are loose and relaxed.


I really hope this helps. when i learned about this stuff it made me so much of a better rider.

I know the hot spots. That AMC24 is huge with street racers and stunters, not only that but like I said the Five-0 knows all about that shiat. If you go through the parking lot at night especially on the weekends you can see em sitting in the unmarked cars. Last weekend I counted 4 plus a van all with fuzz inside waiting, Douglas County

How did I know where the scene is? Simple, if your hanging out at the Conoco or the proving grounds (the only place where you would be going if you got off 1-25(death trap that it is) onto sante Fe(crappy road that is) and your from Highlands ranch, AMC24 is the spot there.

Dude,

Seriously find another spot er your gonna get nailed. Channel 2 news did a story on stunting recently and that means they will be cracking down. Besides that theater is really bad for theft and a butt load of other stuff, too many fast and ridiculous guys there anyway.
I actually heard of the AMC from a cop(guy I know from the Marines)
