It was one of Harley-Davidson's attempts to enter the small displacement off-road motorcycle market.

It had a 98 cc (6.0 cu in) two-stroke, single cylinder engine with five speed transmission, derived from the current two-stroke production, mostly Aletta and Aletta d'Oro off the shelf parts by reducing bore from 56 mm to 50 mm.

The only purpose-made part was the frame to accommodate for the front holder for the cylinder head and the air filter box.

But for some early "street models" the MSR frame numbering may apply.

There were other minor differences such as the rear fork or the missing vent on the tank.
