tank slappers?

anyone ever been in a tank slapper situation and knew why it happened? i had my first experience last night and it scared the s#!t out of me. i was takin a right turn from 45 n onto 59 s. i came onto it at 90mph. i pulled my a$$ out of the saddle and accelerated up to 115 comin out of the turn. all my weight was on my right knee and when i straightened out my forks the front tire wobbled for what seemed like a forever 4 or 5 secs. i thought i was about to get tossed off the bike for sure. it smoothed out and i pulled over right away to think about what just happened. i'm curiuos to know why it did that.

Racer X gave a pretty good answer... that t don't generally happen at normal street speeds.

I've had plent of them on the track, it usually happens when your front tire lands slightly offcenter. The way to get out of a tankslapper is to slide back in your seat and give it gas. It unweights the front end and allows you to straighten the bars. NEVER get hard on the brakes while experiencing a slapper, it only worsens the problem.

A steering damper helps, but won't prevent slappers...

ya, ive had a few. it can be caused by a few things.

in most cases, for some reason the front end is unloaded a bit, maybe because of excessive acceleration, poor suspension setup, a crest or bump in the road...seems to me like being in a turn can multiply all those factors.

a good steering damper. (ohlins, scotts, GPR, etc) can help eliminate or reduce the effect of slappers. i highly recommend them, but at the same time, try to find the root of the cause rather than just treating the symptom.

check your tire tread, air pressure, go get your suspension setup at Motorcycles Unlimited, etc, but i would put a good damper on the bike also.

i also got a nasty slapper one time on 59 s near hillcroft. i was cutting traffic and as i changed lanes at high speed, i noticed to late some debris in the road. it looked like an inner tube, but could have been any kind of rubber trash.

i had an ohlins bar damper at the time, and i kept it pretty stiff. it saved my for sure. even with the stiff setting i got nasty headshake, i couldnt have held onto it without the damper. eating it at like 100 mph in traffic would not have been a good day.

+1 to what Racer X said, The only time I had a bad one was when I left a stop sign, accelerated fast, front wheel came up a bit and came down on a stone or something, scare the out of me, thankfully I had enough room to grab more throttle and smooth it out.

all I know is that I wear my gear and take it easy, the guy was asking why his bike responded like that...maybe it was his technique??? I sure as don't know but again...maybe someone will give you a real answer huh Jason?

btw, when we give advice like this, and we come off harsh, its prolly cuz we've been dumb and done the same thing years back, was lucky enough to learn from it, and passing that knowldge along.... not because we think we are better than anyone. Thats simply not the case.

that's the odd thing. i just had my suspension setup on wed at Motorcycles Unlimited. i thought that might of been why this happened. i've takin that turn multiple times at the same speed and never had this happen.

Here is a prime example... look at how his front tire comes down, crooked.
