WAY COOL! Are those the types used for those long distant rally's? Is Maico still in business?

I recently did an on-line search for Yamahas just out of curiosity and was shocked all the MX bikes were all four strokes. I didn't find anything, but I was looking for some kind of motorcycle similar to the 'enduros' of the old days that were light weight and built similar to motocross bikes with street legal lights.

Back in the day, we used to talk about how cool it would be to have a four stroke that was light enough and quick enough to be competitive but it didn't seem there ever could be. There would be many advantages to a four stroke, but back then two strokes were just too fast and outclassed four strokes. Every MX back then was two stroke and the smell of 'bean oil' and blue fog permeated the air around MX races. We had to carefully mix the correct ratio of gas and oil or it would end is a seized piston. Sometimes it did anyway.
