25 mm ATG on MC sidecar?

Need something more like the '70s West German Faun Kraka

Rheinmetall 202 20mm for the win

3/4 ton cargo capacity, 35-40mph. Weighs 1600 pounds. For Airborne use also, the basic cargo version could fold up

It uses a BMW flat twin for power. No reason not to have something like this in the '30s.
They are indeed wonderful and I thought of something similar but went for the MC/sidecar as that was already available technology and being produced in great numbers - and not at least cheap :)
 
If your going do four wheels why not a Bren or Universal carrier ?
Money.
far easier to repurpose a motorcycle engine and simple automotive drivetrain, than an open topped AFV that needed a V8 to move its 3 ton noisy chassis about.

Wheels are cheap, light and quiet
Tracks aren't

The Faun was a cheap replacement for Jeeps, since the Germans didn't like the larger vehicles NATO was going for, or overdesigned stuff like the Ford Mutt,
and the local 3 cylinder 50HP DKW Munga 'Jeep' was discontinued.

And unlike the US Mule, the Kraka was reliable and had decent off road capability, as well as on road, with 10-15mph more speed.
The Mule didn't have a differential. Or suspension, just the flex in the low pressure tires.
No so much fun at high speed.
 
Would something based on the VCL Utility tractors be too slow? More expensive I'd think, possibly too slow, but quite doable. Or the Vickers MG carriers. Some of the tractors are as small as the vehicles above.

Ok, I have to ask, what army is that? I'm guessing Swiss because of the helmet and the muzzle brake on the gun.

yes, it is swiss, he is pulling a Tank Büchse 41, 24mm

Very interesting! Here you get a 24mm semi-automatic gun at 74 kg, it appears it should possible to a have a 25mm sliding breech single shot gut at under 100 kg. The site doesn't say anything about muzzle velocity, but at least the barrel should be long enough to achieve a high MV (900 m/s?). Judging from the rather fragile looking mounting the recoil would be limited - also good for my MC/sidecar :)

AP shot of 225g at 900 m/s, or with some 1/4 more muzzle energy than the Soviet VJa-23. A bit less power than French 25mm AA, and much less power than the French AT gun, that was inn the ballpark with ammo for the USN 1.1in and German MK-101/103.

Here are some motorcycles armed with anti-tank rifles.

Russian M72 with anti-tank rifle

I can see why he's aiming over the bach of the sidecar, the recoil will help them get away quicker when the shot bounces off the target. Seriously though with any anti tank rifle you're more likely to break your shoulder than damage a tank.

Depends on where you aim. The Russian AT-rifles were the reason for the introduction of the Schurzen on German Tanks/Stugs. The Rusians went for side shots on the lower hull (between the returnrolles and the roadwheels). The armor there was thin enough to penetrate the hull.
