Ah the old Street/Flat track discussion. I agree that the XR750 is one of the coolest flat trackers ever built and that a dirt tracker is meant for a single purpose. Street trackers however are more of a tribute to the old flat track generation and are purpose built for the street. If your wondering why you would build a off road bike and put it on the street I can tell you from my Supermoto racing experience that it is just plain fun. The XS650 is probably the most popular for Street and Dirt track recreations. I built my XS650 as a Street tracker with a modern twist because I wanted a bike that had a comfortable riding position, handled well, had great suspension and brakes. I have built and ridden several cafe racers, but my tracker is my favorite to ride. As far as opinions some may like or not like what you create "Who Cares" Build it because you think it's cool. I did, many people like my build and some didn't because it was not traditional enough. In the end I created the bike that I wanted.
