This matching numbers model 121 was found in the back of a cycle shop in Erie PA. A cosmetic restoration was completed in six months. Every part was polished, painted or plated. A local auto body shop did the painting of the fiberglass. I would guess 98% of the hardware is the original Bultaco. The bike has Pirelli Tires front and back. The original wheels, spokes and hubs are still beautiful after all of these years!!!
