The heating system also took care of the riders feet... a cone shaped defuser was situated on each side of the bike.

The sidecar passenger also got some warmth. Seen here is the heater tube (in black) that got routed around the foot rest board in the nose of the sidecar. The exhaust gasses exited the body on the right side, down near the sidecar frame tube. A wheel spacer is seen resting on the spare tire carrier center shaft, where the retaining nut should be.

I was walking around a Harley swap meet several years ago, and spotted this KS750 engine out of the corner of my eye. I walked over and asked the fellow how much he was asking. "That depends" he says "What it is?" When I told him it was a Zundapp, he says "Zooon dap, what the hell is a Zooon dap?" After I told him we agreed on a price and I bought it. He sold a doorstop that he had been carrying for a while, and I got a complete engine, trans, magneto and original carb for a price I would have paid for the magneto alone. The engine had been used as a stationary power supply, and the kickstarter had been replaced by a long steel shaft which was connected to a new starter mechanism.

Not the best quality photo, but useful to illustrate a point. Some people mount the twin 50 round ammo can carrier rack in this position, off the back of the sidecar. I have it on good authority that this was never done by the Germans during the war. It seems to be where they were mounted by the authorities in Spain, who used a lot of R75s during and after the war. There's an interesting story of a German ship headed for North Africa that docked in Spain after hearing that the Allies had just landed there. The ship had a cargo of R75s, and as a condition of its release, the bikes had to be left in Spain.

This photo shows the ammo can carrier mounted in one of two proper positions - just outside the sidecar body, within easy reach of the sidecar passenger. The other correct position is just in front of the sidecar seat lower cushion, behind the sidecar passengers boots. This sidecar body is actually a mix of an original R75/KS750 body grafted to sections of a Ural sidecar body.

A famous war time photo showing an R75 with the very late style sidecar fender (see my photos a few pages back), and the reason it was adopted. The photo even captured the blur of the sidecar wheel spinning in the mud.

If you look closely at a KS750 engine, you can ALMOST see that it's not a flat twin at all, it's a "V" twin. A joke? Not at all... the designers angled each cylinder up 5 degrees to improve ground clearance, so the engine is really a 170 degree (wide "V") twin.

At first glance the KS750 rear drive unit looks identical to the R75, but there are some detail differences. If you look closely, you'll see a small vent on the top side of the case, just in front of the large upper mounting hole. Only the KS750 rear had this. There are also some additionl numbers stamped into the large inner case, just above the oil filler bolt. The KS750 also had a different ratio ring and pinion gear set - though the final reduction was the same - the KS750 just took more teeth to do it. This is the rear drive from my 1942 KS750, after restoration.

With R75 and KS750 parts, NOTHING gets wasted! This donor trunk section was just the thing to fix up an original sidecar body that had been modified to remove the trunk area and add a second seat!
