Funny how the pinnacle of racing limits the inventiveness of the designers.

The Elf Hondas tried them in the early eighties

When you look at that, it's the single sided rear suspension which has caught on, which offers no performance benefits. Wonder what axed the front swingarm design which does offer performance benefits. The steering I guess?

Single sided swingarms are more of a fashion statement than anything. The only benefit they offer is when it comes to changing the tyre.

When Elf tried their experimental bikes in the late 70's to late 80's they never really gained any success with them. I don't know if they won a single race (someone else might know).

They are quite often heavier than double sided swingarms to

Kinda makes sense when you think about it, as they have to be twice as strong, and the axle housing etc...

You might be surprised, a lot of engineering goes into a SSSA, while in many cases two bits of RHS are just welded up for a double sided one. A bigger cross section gives you more strength per weight than a smaller remember. For example an RC31 SSSA is 4.1kg, not sure what the weight is like for a double sided one, but can't imagine there being a huge amount of weight savings to be gained.

I am putting money on the Kawashitty having a heaver swing arm.

Wow that is one insane power to weight ratio

Not sold on the looks yet but I'm sure I'd feel differently if I had the chance to see one in the flesh.
Definitely wouldn't put myself on one of those as a rode bike, I had enough problems keeping my 250bhp Subaru under the speed limit with its chunky 1470kg.
That thing would either kill me by going to warp speed before I could blink or would get me to pass go without collecting $200 straight to jail

From what I've only read, riders of the Vyrus (and for that matter the Tesi) have complained of a vague feeling from the front. A lot of riders (through experience I guess) prefer the feeling of a bike diving under brakes entering a bend. Also it works to shorten the steering rake, thereby increasing the turn in rate (from what a certain suspension dude told me).

As far as SSSA's, they are, nay, were effective for endurance racers, but now with quick release systems for DSSA's they really serve no purpose other than marketing.

For the normal boring riders like myself I would never experience the funny front end as I wouldn't ride it hard enough... shit I've got dirty chicken strips on my CB

Also, the "draw backs" of an SSA would be wasted on me too, I am happy with the way a ZZR4/600 handles...so a real bike with an SSA is more than I need and I doubt I'd ever notice the difference.

Just saying... yeh, I ride like a pussy

I hadn't read of the 'vagueness' thing but I have read that it feels rather bizarre without the normal dive.
Another advantage of it, if I recall correctly, is that the back wheel doesn't lose as much contact with the road under braking so that you have the extra braking available and more control of the back end.
