Hirth 3202 2 cycle 55hp

Special Design - High Torque/Low Rpm Engine

The 3202 produces 55hp at only 5500 rpm while building an impressive torque of 53.2 ft lbs. at only 5000 rpm. Operating in an Rpm range 1500 Rpm less than conventional 2 cycles results in a very smooth and quiet running engine with impressive power. Fuel rate is lowered and TBO increases.

3202 incorporates Al-Nikasil coated cylinders for superior performance and reliability. Al-Nikasil in simple terms is a nickel based material, applied in a paste form, when super heated it becomes part of the cylinder itself. Al-Nikasil provides for a super low coefficient of friction, reducing engine heat and wear.

The pistons and cylinders expand at the same rate thus providing for a seizure resistant engine. 3202 crankshaft is 4130 chromemolly steel.

Heads, cylinders, rings, block casting, connecting rods and associated components are all of the highest grade alloys available.

 Factory recommended TBO is rated at 1200 Hrs. @ 75% power.
