Chandler winning again on his Freddie Spencer Racing Honda RS750.
They are right about the changing track conditions at Ascot. They would prepare the track really wet and tacky for some Nationals and it would make the bikes handle really nervously, wallowing around coming off the corners. It had something to do with the weather also. If it was cold at night ,which it often was at Ascot, the track would stay moist and groove up. On hot summer nights it would be softer and way more racy. Between heats they would groom the track by dragging it with big section of cyclone fence with some rail road ties on top. This spread the cushion around and provided a perfect racing surface, enjoyed by the riders and spectators.
