Product information "EZ77 V4 Single Cylinder Engine"

The EZ77-V4 engine is a further development of the proven EZ65 engine. The Nicasil-coated cylinder has a larger bore at the same size. This reduces its weight, resulting in better overall performance. Similar to EZ50V4, this engine can also be equipped with two silencer versions. The colored add-on parts are available in blue, red, and black. Single-cylinder engines are supplied with blue components as standard. EZ77-V4 engines can also be supplied with counter-clockwise rotation. This engine is also available in a long edition. (EZ77-V4 LE)
