Soichiro Honda, 1906-1991. He worked at home in his father's garage for bicycles and motorcycles.

He realized, after the WWII, that people needed transportation vehicles and bought one stock of surplus mc engines. With these he built his first mc 1947 and called it Type A. (Bugatti called his first car for Type 1).

1948 he formed Honda Motor Company. When he got his partner Fujisawa, who also had the knowledge how to handle finances, they succeeded to roll the company through the difficult years after the war.

In the middle of the 1950th the company started to grow and late 1959 they had a good grip of the market.

1958 he put out an enormous seller, a moped with 50 cc engine. Just what Asia needed. 100000 was manufactured a month!! 1968 the CB750 four was announced.

This was a mc with several new things like electric starter and disk brakes. Now Honda was controlling the market and produced one after the other several hits. Very much depending of that he never let a bad construction leave the works.

He never got a bad reputation. This Honda 750 four in Surahammar MC museum is a motorcycle that made the world astonished and did completely outclass the English mc industry.

Monark M51. The moped history for Monark started in Varberg 1908, when Birger Svensson (1883-1944) registered the firm "Swedish Cycle Depot".

In small scale he started a bussines for cycles during spring 1909 and Carl Bertholdsson and a errand boy.

Even if a workshop was on hand he made no repairing works until 1912-13, then he had about 20 workers.

The success during and after WWI filled his business locals at Kyrkogatan which he had bought 1916 and 1925 it was time to expand with a new factory near Varberg and name change to Varbergs Cycle Factory.

Lutz M58. Otto Lutz had studied machine technic at high school in Stuttgart.

His engine interest became so strong after war that he started a firm 1946. Here he constructed a 49 cc engine with a special view.

The name Kuliwas used by other resellers. The last name was a travestyon the Rickshaws you see in som Asian countries. Kuli is the name of the hauler. This is a good name for a moped engine.

His main idea was that it must be able to mount on all sorts of cycles, without any need for workshop.

To create such a help engine usually is easy in the beginning. But i always come a point when problems arise. In the start it was discussion how the engine should be mounted. Gottfrid had many suggestions to deal with.

Mounted in the front wheel, ont the steering handle insde the frame over the pedal center, under the pedal center on the rear carrier and inside the rear wheel. At last after all considerations he chose to mount it besides the wheel just like Victoria and Saxonet. This idea wa known in Sweden since 1947.

Everything was nice until construction of get the power over to the wheel without dismantle the rear wheel.

But we have forgotten hav the three projectors could put power to the wheel without interfere the spokes.

In the center of the wheel you have the wheel bearing and brake, inside the hub. Around this the three projectors are screwed together clamped together. In this way the foot brake was still working. Then it was onley three wires for gas, compression valve and clutch. Genius. See picture.
