Default First Victory

I live in South GA, right on the AL line. Just bought my second bike. Had a Honda Shadow and just bought a '06 Kingpin Deluxe. Loved it from the start of the test ride. Rode it 2 hours home, smiling the whole way.
Only issue I have had is over 80 mph the saddlebags catch wind and make the back end sway. Speed limit is 70 around here, so 80 is typical. Anyone find a way to minimize this without removing the bags?

Congrats and a big welcome to the Victory Orphanage from the Pacific Northwet.
Are you certain its what you think it is, the aerodynamics of the bag, or might it be something else that can affect that condition? Proper air in the tires; loose steering head bearings; rear wheel alignment and more can affect that "sway."

There is a warning inside the bags and in the owner manual stating speeds exceeding 80 mph can cause the bike to lose control. It only happens over 80. Only makes sense it is the wind. I will have time this weekend to look at the suspension and see if maybe a stiffer setting might solve the issue. Until then I plan to keep it under 80.

This is a new one on me. Can you post a picture of your bike with these bags that say they can't go over 80 mph?

I have semi soft bags on mine and 100 mph is no problem.

I run hard bags on my 09 PIn and have not had issues with the bike swaying over 80. Most MFG state not to exceed a certin limit with bags or trunk. Could be the bags but check everything else.

The more I think about this the more I'm convinced RICZ is right.

There's such a small chance the bags could cause this that it's barely even registering on the chance meter.

Loose axle bolt, worn tires, to add to what Ric said.

One other thing just came to mind. Make sure you don't have a radial tire up front and a bias ply on the back. You can have it the other way around with no problem but if it's like that you can have handling problems. If you don't see an "R" on the side of the back tire but do on the front; there's your problem.

The reason is in the rake and trail of the geometry of the Kingpin in particular. This isn't a well known problem on any other Victory. It seems to only present itself on Kingpins.

PS: Please put the model and year of your bike in your signature line. You can do that through the UserCP. Your location, at least the state, is helpful too for figuring out other issue having to do with climate or where someone can help you.

2010 Kingpin
Length 99.9 in / 2,537 mm
Wheelbase 65.6 in / 1,666 mm
Seat Height 26.5 in / 673 mm
Ground Clearance 5.8 in / 148 mm

2010 Vegas
Length 96.0 in / 2,439 mm

Seat Height 25.2 in / 640 mm
Ground Clearance 5.3 in / 135 mm
Rake/Trail 32.9 / 4.9 in / 126 mm

As you can see; there's a difference and it's enough to make putting a radial on the front and bias on the back a bad thing.

It's actually always a bad idea to do that but it shows up on the KP's more for some reason.
