Engine
The engine is a water-cooled one-cylinder two-stroke engine. The cylinder head and the cylinder
have been cast in one piece.
To ensure even HP output, an exhaust collector with a cooling casing has been permanently
fastened to the engine. Such a collector is necessary in a two-stroke engine as the exhaust pipe
system length, diameter, shape and/or muffler arrangements may vary considerably. To avoid
weight, the exhaust collector has been made of corrosion resistant light metal. This makes the
cooling casing necessary. This casing decreases heat radiation to engine compartment and cools
exhaust gases.
