if you have a 30 mins to spare, check out this video, I thought it was great, I was at quite a few of these races as a youngster growing up in the 70's and 80's. Some of my Idols giving their thoughts on the evolution of the XR750 and how important it was to Flat Track racing.
Riders interviewed include Jay Springsteen (Springer as he was known), Scott Parker (is that a XR1200 tank cover in the background?), Chris Carr, and Jeffrey Carver Jr.. Insights from legendary tuner Bill Werner are icing on the cake. These bikes are what motivated me to get my XR1000 in 1983 and then my XR1200 in 2009. I hope you enjoy it as much as I did. Some of the comments below the video, sting a little bit, people are upset in the direction Harley has taken, but it shouldn't take away from the merits of the video.
