I don't understand the question, but from what I do get, you need to remove the swing arm. The Becker stand will work if you ensure the front of the bike is weighted enough to tip forward when on the stand.
1: Remove rear wheel, Exhaust, Rear Brake Caliper, Saddle Bags etc.
2: Remove Bevel Box
3: Remove side covers that hide the swingarm bolts/nuts
4: Remove ABS/Brake line from swing arm
5: Unfasten drive shaft dirt boot at front of drive shaft
6: Remove Swing Arm lock nut using Triumph special tool
7: Remove Swing Arm bolts using large hex
8: Hold Swing Arm about level and pull straight away from frame, it will come out.
#6 in the diagram has a high torque lock nut on it. It requires the triumph special tool, or to make one using an old socket on some Rocket 3s.
For example my 2014 I could remove with only the allen key easily, on the 2006, I broke a 1/2" drive, 3 foot long breaker bar trying to use the hex only. Special tool was required, and removed it easily.
