The reasons why some wobbles become slappers is even more of a black art than suspension set up.

Bike did an article a while ago after a tester had a slapper on a CBR600RR. They went down the same road at all kinds of speeds and tried to provoke one but didn't get it to slap.

John Robinson also did some research into it but i'm not sure if he put it in a book.

What, live with something as underpowered as an SV so it won't happen?

Not at all Stu, I had one of the worst tank slappers on a Zephyr 550, an underpowerd barge compared to an SV. All about oscilation, momentum and kinetic energy etc etc.

'Zackly. It's nothing do to with power, stick an SV motor in a 636 frame and it'd still wag its bars. It's all about chassis stability. The same things that makes a 636 turn faster than a standard SV also make it more likely to slap.

Also, noticed the 05 and 06 doesn't have the same rep? New rear shock. Max McAllister, who owns Traxxion Dynamics, told me once that he reckons 3/4 of all tankslappers start from the rear- the rear squats, which unweights the front, then as it's part compressed it passes every bump straight through the bike.

Mine slapped like an absolute mofo for a while, because I had too much rebound damping on- it wasn't recovering from bumps fast enough so when it hit the next one, with the shock already compressed from acceleration, away it went. A badly set up SV will slap as hard and as fast as anything...
