Early ST 13's Euro models had some weaving issues as I recall. I vaguely recall something about improper torque on triple clamp bolts.



Honda pulled another howler on the early Euro ST13's. They left a tab in ft of the drain plug which promptly snapped off whilst traversing the much steeper Euro "sleeping policemen" (speed bumps).



Could be something as simple as tire choice and/or tendency towards underinflation....

I guess 'superior' is relative these days, eh? Think the Harley Bashers Club might have a field day if a Harley did this? Nah. Must be tire inflation or some such thing. Right.

The only time I had a bike go into a high speed weave was when I put some cheap, non belted tires on it. This was years ago, but it (Yamaha Seca 750) never did it before or after I got rid of the 'bargain' tires.

The Brits also found a "hidden wobble" on the old Suzuki TL1000, prompting al sorts of un needed changes to the power band and adding a steering damper. Funny how in the end the problem did not really exist and all was OK. I have ridden an ST1300 and it handles fine over 120 mph (on a closed course...Ahem!) Ill bet it is the overloading with cop stuff and skill level of the rider.

Several riders on the ST-Owners.com forum say cranking up the adjustable pre-load in the rear is all it takes to get rid of the high-speed instability. Most people on the forum only experience it with the top-box on at 110-125 mph speeds.

Didn't these guys watch "The World's Fastest Indian"?



Or is this more like a nutation problem?



There's even an interesting Wikipedia article on the subject:
