For twenty years Sandy Poglavec has been repairing, restoring and selling Harley-Davidson motorcycles. The most popular models were not enough for Sandy, so he fulfilled his dream by converting one of his Harleys into a quad. The self-taught mechanic called his invention the Q4. It took him 5 years to develop the Q4, but his efforts have certainly paid off. To get an honest opinion of the result, a long-time Harley fan and an enthusiastic quad driver took the Q4 for a spin.
