I found this copy in mint shape last year and am now impatientit waiting for the day my son know how to read so I can give it to him.
Easy trivia: can you name the rider in the second picture?
Look to the angle formed by the SA pivot, to lower shock mount, and top shock mount. Once that inside angle at the swingarm shock mount goes past a right angle, into an obtuse angle, you are into falling rate geometry. Now, suspension kinetics that rely on a single, basic triangle, don't have a huge ratio change, whichever way you are going, but going into falling rate on a two wheeler just sucks.
And, I'm pretty damned sure the shock they had, had no internal method / valving for positional damping increases - of which there are many ways to achieve, in later years, and, today.
A lot of mistakes were ( and still are) made with engineering, and, the 'Big Boys', who had no excuses ( eg : the first production versions of Kawasaki's Unitraks) showed just how they could royally f**ck things up - not just the little guys.
Hell, I learned my lesson in the mid 70s, when I severely laid down some shocks, having the inside angle going into ( well, further into - but in the 'opposite' 'clocking' direction compared to the PC set up) an obtuse angle. Talk about slamming through the final few inches of travel - it was the start of my back problems, I'm sure of it.
You can look at suspension linkages as a succession of triangles, and their changes through various axis, and their interactions with each other.
As for the bracing on the swingarm : well, the small diameter of it goes well with the forces in terms of them being in tension, but the bracing finishes barely forward of the severe load area of the shock mount, plus, it looks like there is no cross over / joining of them. It can be fun and games having bracing that goes right to the SA pivot section, and as 'across' bracing, but it's perfectly doable. Even on a long travel dirt bike rear end.
The Husky Twin Shock rear suspension geometry of that era was very good (whereas, if you look to say, the dreadful shock geometry of the wonderous Gilera Twin that Ruy put pictures up of, and, many of his [I assume] beloved Montesas) - this Single shock version's geometry would rank 'down' there with the 'worst of'. But, there'll be some here that will get upset with that, and claim it was wonderful. Bullshit to that.
As an aside, the final few years 'White' frame Huskies, with the ITC Ohlins, Progressive springs, an even better shock / swingarm / main frame geometry, I / Many rank as being darned near 2 shock perfection. I've mate with a couple, with damping adjustable shocks, and they are truly great. If any of you have early copies of Dirt Rider magazine, where they graphed Suspension Geometries, Shock Damping ( via dyno ) and Spring Rates / Progression, you'll see the reasons why the Husky rear end could be so good - plus see how all over the place Single Shock linkages leverage ratios were.
I was there the day it was taken and actually rode that bike. It's hard to see, but in addition to the obvious suspension changes it also had one of their 38mm Mikuni kits on it. Retained the piston port, no reed valve. My 76 had the same rear setup and carb kit.
Worked great in a straight line, not so much when leaned over. CG was a "tad" high.
I've said it many times. If those guys had been based in California instead of Destin, FL they would have been heralded as evil geniuses.
What a POS that bike was!
Blue Honda seats, red engines, those were beautiful, and Yamahas were Yellow and black. KTMs and Huskies were expensive POS's and big loud Maico's with floppy fenders and poor jetting ran around the senior class!

Yes, I have multiples of each. Yes, I may have a problem.
I don't recall if they were conventionally finned, or Radial , or Porcupines - but I Do recall that they were bloody Heavy!
Man o man at the aftermarket heads they used to have for the early CR. That little bike supported so many hop up shops in the 70's. A few here from the interwebz. Webco is bottom right in the pic of five heads.
