Is it your bike? Is it still for sale?

Maybe pushed out of an airplane at high altitude.

What a poser. Who does he think he is, Steve McQueen? Give me a break.
 
The three tests I have from them - '69 Blue Streak Special, '70 and '71 all have the top speed around 111 to 116. And 1/4 mile times from a blistering 12.4 to a more lethargic 14.3. Tune, bike, driver all play a part and it was nothing for factories to toss in ringers. A '73 Superbike comparison had a smoking fast Triumph Trident, who on tear down failed miserable. Also a real quick Sportster was also tossed out. The automotive world was the same then. If you had a comparison piece and you used your off the lot product, you lost.

I'm not sure what the terminal velocity for a 1971 Mach III is, but a free fall skydiver is 122mph non-streamlined and closer to 200 mph streamlined. I don't think the Mach III is very streamlined and may have a rough time hitting that 140.
 
On the other hand, on any two stroke it is EASY to get huge increases in power with just a little craftsmanship with a Dremel, a few tricks of the trade, and an expansion chamber. Some of these bikes were very fast indeed.
This idiot's bike has some kind of pipe, although he's hiding it with his stupid ass.
 
I definitely agree with that. One buddy had a 1970 that he used the factory templates for porting, a crude reed valve affair and I think some rejetting and of course the expansion chambers. But the same chassis. The thing would destroy stock Mach IVs when they came out, but after 80mph or so things got twichy. 100mph plus was an experience. However all those Mach series were flexi-flyers.

And why is buddy posing like that? Unless a "friend" found them and onlined them for giggles and chitz. And I have never seen any aftermarket Mach series pipes with all three out the same side. Scarce (for a reason) or homemade?

And some sort of funk going on for the instrument mounts. Honda blinkers. Anyone's but stock mirrors.

Just did a quick scan of eBay and there's quite a bit available for pretty decent prices.

That pipe would have to be homemade, which is why it is not shown. All production chambers had the left cylinder's pipe on the left, and the other two on the right.

I think you mean this 1969 comparison. By '73, nobody cared about the H1. It was all about the KZ900 and H2. The Trident had a second gearset from a Bonneville in it, but the testers let it go. As you can see, it was not tossed out. 12.4 was advertized. I never saw a test that was close to that.

1972 Comparison with H2:

I like that the Commando and the Trident, now with a 5 speed are way closer to the H2 in accelleration than the CB750 was to the British bikes.

As 1 reference, here is a 1971 CW test of a much quicker but limited production bike:

With all due respect, Commando, you are comparing apples to oranges. Rather than a massaged 750 Commando, compare the actual Norton 750 Commando and its figures. That would be apples to apples.
I personally felt the Norton was the best of the British bikes, btw, back in the day, and was the one I always wanted.

They are there, in the '69 and '72 comparison. The Dunstall was a production bike., though a warmed over Commando it was.

It is interesting that in the '72 comparo, the Sportster beat the Honda.
