Pan Weave

I have a copy of that edition of Ride magazine. They didn't test every combination of windscreen and luggage and pillion and speed, but they gave it a pretty good go. Some of the results were alarming and reproducible.

I'm in the no weave group with speeds up to about 150 kph I think. There was a bit of pucker factor however. I have a topbox on it as well. Mine is a 2014 so maybe the design was tinkered with enough by then?

RiDE Magazine reported in October 2007 that a team replicated weave instability mode with a civilian Honda ST1300 – reproducing the instability at a speed of 110 miles per hour (180 km/h)

YOUR GOING TOO SLOW :rofl1:
 
[edited] Whats described in post 75 seems pretty much consistent with various accounts and the bikes are getting old. I don't understand how changing the torque on the frame to engine bolts can be cited as improving anything unless these components were shifting in the first place. Replacing bushings raises more questions than answers as well. I guess they made some changes that satisfied some experts. But in the end it's adjustments or modifications that didn't entirely solve the problem twenty years ago let alone how things might work tens of thousands of miles of wear and tear since.
What's more is that following the fatality a group attempted to reproduce the weave under controlled [probably more like monitored] conditions with a skilled rider in which the rider went down. So, you have to imagine it amplified pretty quickly and that a skilled rider, fully anticipating the event couldn't avoid losing control.

Well, this thread concerns me I've only had my ST 1300 for a few days although when I first test rode it I did hit the interstate highway for two exits and I got it up to 100 miles an hour (but only for maybe 20 seconds at that speed).

The windshield was almost all the way up because I like to sit rather upright.
All 3 storage compartments were empty but I certainly put plenty of weight on the bike just from my body I probably weigh about 320 pounds with all my gear on.

I didn't notice any instability .
 
I don't think I would ever take the trunk or either of the panniers off my bike-- I got it for touring and I intend to use it for that often and keep it configured that way.

So, I've got to figure out what is a safe maximum speed, even if the highway has some grooves in the pavement and even if I'm going to be passing semi trucks. Or riding in a crosswind.


I was hoping that my maximum safe and reasonably comfortable speed on this bike would be 110 MPH which I probably would only use out West, not in the area where I live.

BUT I see other people have posted in this thread that they've got the wobble/weave as low as 63 mph! (?)

I could live with limiting myself to 90 mph
 
I have always thought that what many people attribute to Pan Weave is not actually pan weave. What they are feeling is the motorcycle responding to localized wind patterns and turbulence from surrounding traffic that they maybe have never experienced from other motorcycles. I have read reports of pan weave from people who came to an ST1300 from a cruiser or sports bike. They had never ridden a fully faired bike previously. Fully faired bikes catch more wind and respond more to the effects of that wind. Very often people will report this happening in either windy conditions or when in dirty air like from heavy truck traffic. Pan weave is a distinct instability movement pattern the cause of which was identified by Honda back in 2002 and it was not related to air movement. Honda claimed that after identifying and correcting the issue that caused this no ST1300 has left the factory with this defect. Maybe the ST1300 just responds differently than most fully faired motorcycles due to its fairing design. I don't know, but I do wonder how many of us are misinterpreting what the motorcycle is doing as a pan weave.

I’m guessing that you have never experienced the Pan Weave. It’s so different from crosswind induced or movement from turbulence it cannot be mistaken anything else.

Weave instability mode at high speed | ST1300 Related

Was wondering if anyone has experienced this! I have had two longer rides on my ST1300. The first I got to 0ne hundred by the speedo and the the second to 130 and did not experience and instability! I was riding single both times.. Mine is a 2006 with ABS..

Exactly my point- That many people who claim to have pan weave may not really know what it is or what it feels like. They might be experiencing other handling characteristics that are foreign to them and they attribute these to pan weave when it may not be.

Some of your previous posts led me to understand that you were attempting to worn of the same possibly incorrect conclusions with regard to pan weave, and were attempting to dispell the same confusion surrounding the issue.

The two separate things get mixed up all the time. The so-called Pan Weave is a side to side weave where the rear of the bike is oscillating and occurs over 110 mph or more. It may or may not ever occur on your bike and seems to be influenced by crosswinds, accessories, and loading. The dancing around or light steering "happy feet" effect in traffic or turbulent air is not the weave. All ST1300's do this as do many other bikes in dirty air. This is aerodynamic and can happen at legal freeway speeds. Lighten up on the grips and get on down the road. Most of this internet buzz would go away if hand grips were called hand rests.

It’s my opinion that even the best sorted ST1300 will have a nervous feel in dirty air at highway speeds. I called it ‘happy feet’. The forks don’t have a lot of rake, it has a shortish wheel base, and a large broad-in-the nose fairing. I do not think it is inherently unstable it’s just not as stable as many other motorcycles are in the same conditions.

And know that this nervous trait is not the same as the Pan Weave at 115 to 130 mph. Don’t be scared yours is going to suddenly go into a wild fork wobbling tank slapper. The weave oscillation starts out slow in frequency and magnitude and in my experience only increases with speed. I confess to have ridden a lot in the weave exploring it. Deserted empty roads don’t try this at home etc.. It’s just not going to show under supra legal speeds and if and when it does it’s gradual in onset. The ST1300 under WOT is starting to lose its best rapid acceleration rate by 120 or so and we just don’t pass some triple digit speed weave threshold so fast we can’t back out of it.
