Shock Absorbers Aren't

Jim,

In your article about shock absorbers, you mention a "tank-slapper" causing "no doubt about it, a dumped bike." This is definitely not true. As a former WERA production-class roadracer, I have seen and personally experienced lots of "tank-slappers" as bikes built for street riding were pushed to their limits (and beyond!) on the racetrack. On the contrary, a tank slapper RARELY causes the bike to go down, even if you do not know how to deal with it.

Telling people it is a sure crash situation will certainly cause some people to panic if it happens to them, and possibly make the worst of what should be just an unsettling or scary moment.

In the event of a tank-slapper, don't panic! Try to shift your weight back on the bike by gripping the tank with your knees and putting pressure on the pegs. It will pass quickly, leaving you with an exciting memory of the day's ride!

I agree with Mr. Bob Scott that a 'tank slapper' is nothing to panic about. I disagree with his attitude that without knowledge, you'll be fine. I noticed that the article had his comments added to it, I liked that but would like this added too if possible.

I have experienced 'tank-slappers' many times on both the street and on the racetrack. By accelerating (which is again not part of our usual survival tactics), one can usually shift weight back on the bike (and lighten the front) automatically and gain control of the front end again. 'A dumped bike' is the result of fighting against the bike usually.
