This OWA story is a "free" translation from Nisse Wedins Swedish story, originally in the Swedish magazine MC Veteranen.

Olle Wallentin Andreasson is the man behind the OWA motorcycle. He is also known as Fällekrokar’n from the place were he lives. He lives in his parents home where he have had his workshop since the 1950s. Olle’s father was a farmer, but Olle have always been interested in technology and engines. In his workshop he started to repair and sell chainsaw’s and when the farmers needed help they came to Olle in Fällekroken because they knew he could repair just about everything.

Obviously when the local boys started driving motocross they came to Olle for rebuilding their bikes suspension, seats, changing tyres and so on. Some of the names from that era in the late 1950’s was Hilding Löfberg, Olle Olofsson, Agne von Essen and also Olle’s cousin Jan Finberg who like Olle was very innovative.

Olle built the two first OWA bikes for two other boys from the neighbourhood, Bo Pettersson from Snälleröd and Bengt Ahlström from the neighboring farm. They both competed for Hyllinge motorclub in the 500cc class with their OWA/BSA bikes. Bo earlier drove an Ariel and Bengt drove Monark Blå Stinget and Greeves.

1964 May 18 in the Swedish GP at the Knutstorptrac Bengt won the juniorclass and Bo came 13^th at the "big" GP race with their OWA bikes.

The same year Karl-Erik Bonn started out his mx carrer on a red 250cc OWA with a Flink engine, at that time competed for Hyllinge Motorclub, later Sösdala Motorclub. But 1965 when his younger brother Bengt-Arne Bonn also wanted to compete Olle had his ideas about the engines aswell. Olle tried to buy crank’s, pistons, cylinders and cylinderheads from the Husqvarnafactory but they denied. But when Olle told them that he would stop selling their chainsaw’s if that was the case, they changed their minds and helped him with this.

At first Olle built two engines for the Bonn brothers, he modified the silver arrow engine with the 250cc crank, cylinder and other gearing with a "high" first gear. As a result you could often see the Bonn brothers first out from the start with their lightgreen OWA bikes.

This season was very good for all OWA drivers but especially for Bengt-Arne Bonn who scored the 250cc Junior Swedish National Title.

Olle now wanted to build his own engine and started casting a cylinder and head with tranfer canals made by loose pipes. But suddenly the cylinder and head mystically disappered from the workshop and wasn’t found until a year later! Still "nobody" knows what happened. This was also the sad end for that project.

Instead Olle and Jan Finberg built a 250cc prototype engine with Husqvarna crank and cylinder and a Flink head on a DKW crankcase, battery ignition from VW and separate gearbox from AMC. Jan Finberg handmade the transmission housing. This prototype engine was put in an EG chassi and Bo Pettersson drove the bike to a 3rd place in a race at Skillingaryd in October 1964.

For the next season a new "double pipe" chassi was made for Bengt-Arne Bonn who tried it but choose to use his old chassi instead. Also 1966 was a very good year for Bengt-Arne and because of that Bror Jaurén from the Husqvarnafactory gave him a new Husqvarna engine and gastank for his bike.

Olle and Bengt-Arnes father, Kalle Bonn continued to prepair the engine for him and once when Husqvarna had made a service on the engine Olle found a written note with a-thank you for all the "tech tips" on it.

One more OWA "double pipe" chassi was made for trials driver Göran Lundgren. For that bike Olle also constructed alternative gearing on the silver arrow engine for the transport routes, with two gears on the crankaxel and two on the clutch drum, 2x3 speed.

Later the Husqvarnafactory and Göran Lundgren developed the, (2x4), 8 speed engine out of Olle’s idéas.
