Guys, decel wobble is complicated. Lots of things bear on it.
Rich, I understand your comments and the validity that they have.
I believe that this motorcycle was designed to carry the weight of a rider, a passenger, side cases and a top case; that are all packed with gear.
I also believe that this motorcycle was designed to operated with a host of different brand tires mounted on it as well. (Personally, I have mounted seven different brands of tires on my wheel rims.).
I DO know that excessive weight, mounted towards the rear of the bike, CAN cause the wobble phenomenon. This does need to be monitored by the riders who have installed the larger Givi topcases and have filled them!
In taking into consideration the multitude of of riders who weigh differently, the different bike setups, (suspension considerations, cases, and gear packed into them), and the types of tires mounted up, there seems to be one common denominator; Deceleration Wobble.
I believe that the tension on the stem bearings, set at the factory is too loose. There are just far too many comments about "Wee Wobble" to not consider this. The wobble is present on old versions of the bike, as well as brand new versions too, (no worn tires.).
To tighten up the stem bearings until there is a distinct "firmness" to the compressing nut, then backing that nut off no more then a half of a turn, is a very reliable method to obtain a "starting point" for stem bearing adjustments.
I feel that, if riders are experiencing Deceleration Wobble, the stem bearings are the FIRST place to start resolving the issue, (if the rider cares to!), before throwing money at tires and other devices like steering dampeners. (And no, I am not saying that steering dampeners are a waste of money!)
What I am suggesting is, that a rider go to the "epicenter" of the symptom, (the stem bearings), check that out first, BEFORE moving to the other areas of their motorcycles to find a solution.
