which is known to flex under load
The commando push rod is 3mm longer and only has to push 220lbs. flex??? this is a first in 30 years...even BDM never mentions it...or I missed it...
Even the RGM instructions do not even mention flexing.
Is this kit necessary for the "NEW" style circliped clutch center?
For me your argument for this kit lacks merit.

NEEDLE ROLLER CLUTCH PUSHROD CONVERSIONDETAILS AND FITTING INSTRUCTIONS
.
The purpose of the needle roller conversion is to reduce clutch drag, whilst at the same time helping to eliminate oil contamination which causes both slip and drag.
Clutch drag is reduced in two ways. Firstly the needle roller bearing reduces friction between the clutch and pushrod. Secondly the flat area of the mushroom and adjuster assists the clutch pressure plate to lift squarely.Oil contamination. There can be a problem with clutches becoming contaminated with gearboxoil. This is pumped along the mainshaft by the clutch pushrod, segmenting the pushrod helpsto eliminate this
CONTENTS. (FIT IN THIS ORDER)
1 SHORT CLUTCH PUSHROD
1 1/4 1/4 ROLLER (THIS IS USED AS A PACKING PIECE AND WILL NOT BE NECESSARY ON MACHINES FITTED WITH A SHORTER GEARBOX MAINSHAFT)

2 THERE MUST BE A MINIMUM OF APPROX 3/8” BETWEEN THE GEARBOX MAINSHAFTAND THE INNER FACE OF THE CLUTCH PRESSURE PLATE. THE EXACT AMOUNT AVAILABLE DEPENDS ON THE THICKNESS OF THE CLUTCH PLATE STACK. THEAMOUNT REQUIRED CAN BE REDUCED TO AROUND 1/4” BY REMOVING THE THRUST WASHER AND RUNNING THE BEARING DIRECTLY AGAINST THE ADJUSTER, THIS WILL ACCELERATE BEARING WEAR BUT WE CAN SUPPLY NEW NEEDLE ROLLERS FOR £2.70 INC .REMOVE OUTER CHAINCASE AND CLUTCH OUTER PLATE (THE ONE CARRYING THE ADJUSTER) AND CLUTCH PUSHROD INSERT SHORT PUSHROD INTO MAINSHAFT FOLLOWED BY 1/4 1/4 ROLLER FOLLOWED BY 1/4 1/4 BALLFOLLOWED BY MUSHROOMFIT NEW ADJUSTER, SECURE THRUST WASHER AND NEEDLE ROLLER TO ADJUSTER WITH A LITTLE COPPER SLIP OR HIGH MELTING POINT GREASE, (JUST A SMEAR).ASSEMBLE CLUTCH AND ADJUST AS STANDARD.NOTE!

You don't need this kit... The CCRS you now have is all you need.
It
might have value in a atlas coil spring clutch
The description of reducing "clutch drag" is not the definition of inter plate drag which adversly affects finding neutral or pulling the bike while in neutral.
Clutch rod to clutch center drag is microscopic in the big picture.
