Friend of mine just bought the husaberg 2 stroke the new one. 2 strokes are definitely taking over. He went to brouwers motocross shop in the Netherlands and they wanted to sell him a second hand 4 stroke. They told him only 30 hours on the clock or something and totaly rebuild engine!!! New bike sir!! He asked :"why did it need a total rebuild after just so little hours"he told him his gas gas 300 already 6 years old and he did not even had to change the sparkplug!!! So he bought the 2 stroke.
