    So this is actually a cruiser but what’s really interesting is its engine configuration.

    The Neander is an air and oil-cooled twin cylinder where the 2 pistons move up and down at the same time, kinda like a big single.

    The really interesting bit, however, is the twin crank design with 2 conrods per piston. The 2 cranks run parallel to each other but turn in the opposite direction to each other, thus cancelling out the vibrations usually inherent in a big single or twin-cylinder engine. Each piston drives two conrods, one to each crank.

    This is not a new idea as apparently Velocette made a few parallel crank, supercharged, 500cc race bikes in the late 1930’s.

    The Neander Diesel Twin is 1340cc and puts out 112HP at 4200rpm and 154NM of Torque at 2600rpm.
    The engine is an air and oil-cooled vertical twin-cylinder with 4 valves per cylinder, 2 overhead cams and common rail injection. It is turbocharged with an intercooler and has a 6-speed transmission with belt final drive.

    The Neander motorcycle was released in 2014 and Neander doesn’t seem to have developed their motorcycle or released any new models since, however, they have built a range of outboard motor engines using the same technology.

    This is in german but has some good animations
