Yamaha Sterilgarda riders Cal Crutchlow and James Toseland spent the first day of the Assen race weekend working hard on setting up their bikes for tomorrow's Superpole heats. Crutchlow got quickly down to fast consistent laps, spending the majority of the first qualifying session in second position. Two crashes resulting from losing the front end disrupted his session although he was unhurt and came away from the heat having demonstrated a consistent fast race pace.
