A Brief History of the Marque
Rotax began life in Dresden, Germany in 1920. It was incorporated into the Sachs group in 1930 and moved to Schweinfurt. In 1943 it was moved to Austria where, in 1959, it merged with Lohner-Werke. Lohner-Rotax was purchased by Bombadier of Canada in 1970 and built twostrokes for the various Bombadier machines. In 1982 they built their first fourstrokes.
Rotax have been responsible for many highly successful engines including those which power BMW's F650, the narrow-angle V-twin in Aprilia's formidable Mille and its successors, numerous twin-cylinder twostrokes used in powered hang-gliders and a range of horizontally-opposed four-cylinder aero engines. Rotax engines are also used in numerous gokarts and in Skidoo and Bombardier snowmobiles.
Rotax fourstroke singles are used in the extremely robust Armstrong motorcycles, both civilian and military, and in modern Buell and MZ machines. Aprilia won three world championships with Rotax two-strokes, and also use their fourstroke singles to good effect in the Pegaso. Rotax engines were also used in late-model Cotton road racers, ATK and Can-Am motocrossers, and SWM off-road machines.

There was also a Rotax manufacturer of sidecars and components in the UK. Rotax UK.

rotax 250 single air cooled rotary valve
I'm trying to get some info on this 70's / early 80's engine, looks similar to the 125 aircooled rotary valve engine used in the 80's in 125 national karts.
So are these reliable and quick when put up against a Honda red rocket or Yam yz250H

I have a 256 Rotax 250cc inline twin engined ESW roadracer from 1984. Frames was made by Eksju Special Welding and are manufactured in aluminium. It is said that well over houndred was made for mainly Rotax and TZ engines, and that it was one of the first company to produce aluminium frames.

Rotax Engine 250cc kick start
We have a rotax engine on a mini sprint car and it is 2 cylinders and kick start has 2 carburetors and we know nothing eles, we cannot even find a place where oil goes into it. If we send someone a picture could it be identified? We think it's 250cc engine, my uncle had a stroke and he built the car, he cannot tell us anything now.
It sounds like a competition engine from the 1980's. Ed.

rotax london, birmingham, taunton.
Whilst researching a wartime Hurricane accident what appears to be a copper tank was found, marked Rotax london Birmingham Taunton. As it is made of copper as opposed to light alloy I dont think it is part of the hurricane. If you think you can help I could send a photo and details.
There is a Wood-Rotax at the Allen Museum
