Lift adapter for Roadster

If you saddle bags (panniers) on the back then they will make it a bit back heavy. With my setup it only takes a couple of seconds to unlock and remove the bags. Bags such as those by Corbin or the OEM ones may take a bit longer.
 
I have the Corbin bags and my rear is heavy too. I don't bother with unloading them to save weight. Just use some wood on the rear arm. Sometimes a 1 inch thick board does it and sometime it needs a 2 in board. Put nothing on the forward arm. It will balance enough to lift rear and front high enough to do wheel/tire removal and be stable. And I remove the seat and put a strap over the frame behind the tank and strap it to the tabs on the arms for added safety.
 
What happened to your Becker ? You convinced me to get one . . . no good and you've gone to the adapter instead ?

The Becker is great, it's on the bike right now and keeping it off the tires during winter. I can even roll it back and forth on the four coasters which helps (a bit cramped for space). The Becker will still be the go-to solution for winter storing the bike. What it can't do though is hoist the bike half a meter straight up.

I finally had to just bite the bullet when it became sufficiently annoying and I'm now waiting for a hydraulic lift; spotted a great one at the local bike show. Pricey as hell, but it will do double duty - when I want to hoist the bike, I can put rails on it to make it into a bike lift, and when I'm not using it for that, the rails can come off and a round foot can be put on it instead making it a garage jack that can hoist a metric ton, so I can use it on the car too.
 
So here's what I came up with:

A piece of thick steel plate with a couple of angle brackets welded to it that will bolt to the frame mounting holes. The bike is very stable on the lift in side-to-side direction, but flexes a bit too much to my liking front-to-back. I noticed that my cheap Big Red jack is actually causing a lot of the flexing, so I may need to find a better bike lift before the next tire change.

I've never had any concerns lifting my 620lb Harley with this jack, but the Rocket seems to be pretty finicky to balance well, and removing the rear wheel will throw off any balance you had to begin with.

Trim a bit of length off the steel plate so that it will sit on the arm of the lift. The arm is the bit designed to take the weight and so will not flex - or break.

I thought about this before making the adapter. My rationale was trying to get the lift farther back, since when I tried to lift with the rear arm of the jack directly under the frame tabs, only the front wheel came up. With these lifting points, I feel the bike is pretty well balanced (at least as long as the rear tire is on). Of course, increasing the distance between the two lift points would help stability.

I had the bike strapped to the jack and it was rock solid on the jack, but when I tried rocking the bike it seemed like most of the flex came from the jack itself.
